Ethnicity

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Ethnicity

An ethnicity or ethnic group is a group of people who identify with each other on the basis of perceived shared attributes that distinguish them from other groups. Those attributes can include a people of a common language, culture, common sets of ancestry, traditions, society, religion, history, or social treatment. The term ethnicity is sometimes used interchangeably with the term nation, particularly in cases of ethnic nationalism.

Ethnicity may be construed as an inherited or societally imposed construct. Ethnic membership tends to be defined by a shared cultural heritage, ancestry, origin myth, history, homeland, language, dialect, religion, mythology, folklore, ritual, cuisine, dressing style, art, or physical appearance. Ethnic groups may share a narrow or broad spectrum of genetic ancestry, depending on group identification, with some groups having mixed genetic ancestry.

By way of assimilation, acculturation, amalgamation, language shift, intermarriage, adoption, and religious conversion, individuals or groups may over time shift from one ethnic group to another. Ethnic groups may be divided into subgroups or tribes, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent group. Conversely, formerly separate ethnicities can merge to form a panethnicity and may eventually merge into one single ethnicity. Whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis.

Although both organic and performative criteria characterise ethnic groups, debate in the past has dichotomised between primordialism and constructivism. Earlier 20th-century "Primordialists" viewed ethnic groups as real phenomena whose distinct characteristics have endured since the distant past. Perspectives that developed after the 1960s increasingly viewed ethnic groups as social constructs, with identity assigned by societal rules.

Terminology

The term ethnic is ultimately derived from the Greek ethnos, through its adjectival form ethnikos, loaned into Latin as ethnicus. The inherited English language term for this concept is folk, used alongside the latinate people since the late Middle English period.

In Early Modern English and until the mid-19th century, ethnic was used to mean heathen or pagan (in the sense of disparate "nations" which did not yet participate in the Christian ecumene), as the Septuagint used ta ethne 'the nations' to translate the Hebrew goyim "the foreign nations, non-Hebrews, non-Jews". The Greek term in early antiquity (Homeric Greek) could refer to any large group, a host of men, a band of comrades as well as a swarm or flock of animals. In Classical Greek, the word took on a meaning comparable to the concept now expressed by "ethnic group", mostly translated as "nation, tribe, a unique people group"; only in Hellenistic Greek did the term tend to become further narrowed to refer to "foreign" or "barbarous" nations in particular (whence the later meaning "heathen, pagan").

In the 19th century, the term came to be used in the sense of "peculiar to a tribe, race, people or nation", in a return to the original Greek meaning. The sense of "different cultural groups", and in American English "tribal, racial, cultural or national minority group" arises in the 1930s to 1940s, serving as a replacement of the term race which had earlier taken this sense but was now becoming deprecated due to its association with ideological racism. The abstract ethnicity had been used as a stand-in for "paganism" in the 18th century, but now came to express the meaning of an "ethnic character" (first recorded 1953).

The term ethnic group was first recorded in 1935 and entered the Oxford English Dictionary in 1972. Depending on context, the term nationality may be used either synonymously with ethnicity or synonymously with citizenship (in a sovereign state). The process that results in emergence of an ethnicity is called ethnogenesis, a term in use in ethnological literature since about 1950. The term may also be used with the connotation of something unique and unusually exotic (cf. "an ethnic restaurant", etc.), generally related to cultures of more recent immigrants, who arrived after the dominant population of an area was established.

Depending on which source of group identity is emphasized to define membership, the following types of (often mutually overlapping) groups can be identified:

Ethno-linguistic, emphasizing shared language, dialect (and possibly script) – example: French Canadians
Ethno-national, emphasizing a shared polity or sense of national identity – example: Austrians
Ethno-racial, emphasizing shared physical appearance based on phenotype – example: African Americans
Ethno-regional, emphasizing a distinct local sense of belonging stemming from relative geographic isolation – example: South Islanders of New Zealand
Ethno-religious, emphasizing shared affiliation with a particular religion, denomination or sect – example: Mormons, Sikhs
Ethno-cultural, emphasizing shared culture or tradition, often overlapping with other forms of ethnicity – example: Travellers

In many cases, more than one aspect determines membership: for instance, Armenian ethnicity can be defined by Armenian citizenship, having Armenian heritage, native use of the Armenian language, or membership of the Armenian Apostolic Church.

Definitions and conceptual history

Ethnography begins in classical antiquity; after early authors like Anaximander and Hecataeus of Miletus, Herodotus laid the foundation of both historiography and ethnography of the ancient world c. 480 BC. The Greeks had developed a concept of their own ethnicity, which they grouped under the name of Hellenes. Although there were exceptions, such as Macedonia, which was ruled by nobility in a way that was not typically Greek, and Sparta, which had an unusual ruling class, the ancient Greeks generally enslaved only non-Greeks due to their strong belief in ethnonationalism. The Greeks sometimes believed that even their lowest citizens were superior to any barbarian. In his Politics 1.2–7; 3.14, Aristotle even described barbarians as natural slaves in contrast to the Greeks. Herodotus (8.144.2) gave a famous account of what defined Greek (Hellenic) ethnic identity in his day, enumerating

shared descent (ὅμαιμον – homaimon, "of the same blood"),
shared language (ὁμόγλωσσον – homoglōsson, "speaking the same language"),
shared sanctuaries and sacrifices (Greek: θεῶν ἱδρύματά τε κοινὰ καὶ θυσίαι – theōn hidrumata te koina kai thusiai),
shared customs (Greek: ἤθεα ὁμότροπα – ēthea homotropa, "customs of like fashion").

Whether ethnicity qualifies as a cultural universal is to some extent dependent on the exact definition used. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf, do not consider ethnic identity to be universal. They regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups.

According to Thomas Hylland Eriksen, the study of ethnicity was dominated by two distinct debates until recently.

One is between "primordialism" and "instrumentalism". In the primordialist view, the participant perceives ethnic ties collectively, as an externally given, even coercive, social bond. The instrumentalist approach, on the other hand, treats ethnicity primarily as an ad hoc element of a political strategy, used as a resource for interest groups for achieving secondary goals such as, for instance, an increase in wealth, power, or status. This debate is still an important point of reference in Political science, although most scholars' approaches fall between the two poles.
The second debate is between "constructivism" and "essentialism". Constructivists view national and ethnic identities as the product of historical forces, often recent, even when the identities are presented as old. Essentialists view such identities as ontological categories defining social actors.

According to Eriksen, these debates have been superseded, especially in anthropology, by scholars' attempts to respond to increasingly politicized forms of self-representation by members of different ethnic groups and nations. This is in the context of debates over multiculturalism in countries, such as the United States and Canada, which have large immigrant populations from many different cultures, and post-colonialism in the Caribbean and South Asia.

Max Weber maintained that ethnic groups were künstlich (artificial, i.e. a social construct) because they were based on a subjective belief in shared Gemeinschaft (community). Secondly, this belief in shared Gemeinschaft did not create the group; the group created the belief. Third, group formation resulted from the drive to monopolize power and status. This was contrary to the prevailing naturalist belief of the time, which held that socio-cultural and behavioral differences between peoples stemmed from inherited traits and tendencies derived from common descent, then called "race".

Another influential theoretician of ethnicity was Fredrik Barth, whose "Ethnic Groups and Boundaries" from 1969 has been described as instrumental in spreading the usage of the term in social studies in the 1980s and 1990s. Barth went further than Weber in stressing the constructed nature of ethnicity. To Barth, ethnicity was perpetually negotiated and renegotiated by both external ascription and internal self-identification. Barth's view is that ethnic groups are not discontinuous cultural isolates or logical a priori to which people naturally belong. He wanted to part with anthropological notions of cultures as bounded entities, and ethnicity as primordialist bonds, replacing it with a focus on the interface between groups. "Ethnic Groups and Boundaries", therefore, is a focus on the interconnectedness of ethnic identities. Barth writes: "... categorical ethnic distinctions do not depend on an absence of mobility, contact, and information, but do entail social processes of exclusion and incorporation whereby discrete categories are maintained despite changing participation and membership in the course of individual life histories."

In 1978, anthropologist Ronald Cohen claimed that the identification of "ethnic groups" in the usage of social scientists often reflected inaccurate labels more than indigenous realities:

... the named ethnic identities we accept, often unthinkingly, as basic givens in the literature are often arbitrarily, or even worse inaccurately, imposed.

In this way, he pointed to the fact that identification of an ethnic group by outsiders, e.g. anthropologists, may not coincide with the self-identification of the members of that group. He also described that in the first decades of usage, the term ethnicity had often been used in lieu of older terms such as "cultural" or "tribal" when referring to smaller groups with shared cultural systems and shared heritage, but that "ethnicity" had the added value of being able to describe the commonalities between systems of group identity in both tribal and modern societies. Cohen also suggested that claims concerning "ethnic" identity (like earlier claims concerning "tribal" identity) are often colonialist practices and effects of the relations between colonized peoples and nation-states.

According to Paul James, formations of identity were often changed and distorted by colonization, but identities are not made out of nothing:

Categorizations about identity, even when codified and hardened into clear typologies by processes of colonization, state formation or general modernizing processes, are always full of tensions and contradictions. Sometimes these contradictions are destructive, but they can also be creative and positive.

Social scientists have thus focused on how, when, and why different markers of ethnic identity become salient. Thus, anthropologist Joan Vincent observed that ethnic boundaries often have a mercurial character. Ronald Cohen concluded that ethnicity is "a series of nesting dichotomizations of inclusiveness and exclusiveness". He agrees with Joan Vincent's observation that (in Cohen's paraphrase) "Ethnicity ... can be narrowed or broadened in boundary terms in relation to the specific needs of political mobilization." This may be why descent is sometimes a marker of ethnicity, and sometimes not: which diacritic of ethnicity is salient depends on whether people are scaling ethnic boundaries up or down, and whether they are scaling them up or down depends generally on the political situation.

Kanchan Chandra rejects the expansive definitions of ethnic identity (such as those that include common culture, common language, common history and common territory), choosing instead to define ethnic identity narrowly as a subset of identity categories determined by the belief of common descent. Jóhanna Birnir similarly defines ethnicity as "group self-identification around a characteristic that is very difficult or even impossible to change, such as language, race, or location."

Approaches to understanding ethnicity

Different approaches to understanding ethnicity have been used by different social scientists when trying to understand the nature of ethnicity as a factor in human life and society. As Jonathan M. Hall observes, World War II was a turning point in ethnic studies. The consequences of Nazi racism discouraged essentialist interpretations of ethnic groups and race. Ethnic groups came to be defined as social rather than biological entities. Their coherence was attributed to shared myths, descent, kinship, a common place of origin, language, religion, customs, and national character. So, ethnic groups are conceived as mutable rather than stable, constructed in discursive practices rather than written in the genes.

Examples of various approaches are primordialism, essentialism, perennialism, constructivism, modernism, and instrumentalism.

"Primordialism", holds that ethnicity has existed at all times of human history and that modern ethnic groups have historical continuity into the far past. For them, the idea of ethnicity is closely linked to the idea of nations and is rooted in the pre-Weber understanding of humanity as being divided into primordially existing groups rooted by kinship and biological heritage.
- "Essentialist primordialism" further holds that ethnicity is an a priori fact of human existence, that ethnicity precedes any human social interaction and that it is unchanged by it. This theory sees ethnic groups as natural, not just as historical. It also has problems dealing with the consequences of intermarriage, migration and colonization for the composition of modern-day multi-ethnic societies.
- "Kinship primordialism" holds that ethnic communities are extensions of kinship units, basically being derived by kinship or clan ties where the choices of cultural signs (language, religion, traditions) are made exactly to show this biological affinity. In this way, the myths of common biological ancestry that are a defining feature of ethnic communities are to be understood as representing actual biological history. A problem with this view on ethnicity is that it is more often than not the case that mythic origins of specific ethnic groups directly contradict the known biological history of an ethnic community.
- "Geertz's primordialism", notably espoused by anthropologist Clifford Geertz, argues that humans in general attribute an overwhelming power to primordial human "givens" such as blood ties, language, territory, and cultural differences. In Geertz' opinion, ethnicity is not in itself primordial but humans perceive it as such because it is embedded in their experience of the world.
"Perennialism" is an approach that is primarily concerned with nationhood but tends to see nations and ethnic communities as basically the same phenomenon. It holds that the nation, as a type of social and political organization, is of an immemorial or "perennial" character. Smith (1999) distinguishes two variants: "continuous perennialism", which claims that particular nations have existed for very long periods, and "recurrent perennialism", which focuses on the emergence, dissolution and reappearance of nations as a recurring aspect of human history.
- "Perpetual perennialism" holds that specific ethnic groups have existed continuously throughout history.
- "Situational perennialism" holds that nations and ethnic groups emerge, change and vanish through the course of history. This view holds that the concept of ethnicity is a tool used by political groups to manipulate resources such as wealth, power, territory or status in their particular groups' interests. Accordingly, ethnicity emerges when it is relevant as a means of furthering emergent collective interests and changes according to political changes in society. Examples of a perennialist interpretation of ethnicity are also found in Barth and Seidner who see ethnicity as ever-changing boundaries between groups of people established through ongoing social negotiation and interaction.
- "Instrumentalist perennialism", while seeing ethnicity primarily as a versatile tool that identified different ethnics groups and limits through time, explains ethnicity as a mechanism of social stratification, meaning that ethnicity is the basis for a hierarchical arrangement of individuals. According to Donald Noel, a sociologist who developed a theory on the origin of ethnic stratification, ethnic stratification is a "system of stratification wherein some relatively fixed group membership (e.g., race, religion, or nationality) is used as a major criterion for assigning social positions". Ethnic stratification is one of many different types of social stratification, including stratification based on socio-economic status, race, or gender. According to Donald Noel, ethnic stratification will emerge only when specific ethnic groups are brought into contact with one another, and only when those groups are characterized by a high degree of ethnocentrism, competition, and differential power. Ethnocentrism is the tendency to look at the world primarily from the perspective of one's own culture, and to downgrade all other groups outside one's own culture. Some sociologists, such as Lawrence Bobo and Vincent Hutchings, say the origin of ethnic stratification lies in individual dispositions of ethnic prejudice, which relates to the theory of ethnocentrism. Continuing with Noel's theory, some degree of differential power must be present for the emergence of ethnic stratification. In other words, an inequality of power among ethnic groups means "they are of such unequal power that one is able to impose its will upon another". In addition to differential power, a degree of competition structured along ethnic lines is a prerequisite to ethnic stratification as well. The different ethnic groups must be competing for some common goal, such as power or influence, or a material interest, such as wealth or territory. Lawrence Bobo and Vincent Hutchings propose that competition is driven by self-interest and hostility, and results in inevitable stratification and conflict.
"Constructivism" sees both primordialist and perennialist views as basically flawed, and rejects the notion of ethnicity as a basic human condition. It holds that ethnic groups are only products of human social interaction, maintained only in so far as they are maintained as valid social constructs in societies.
- "Modernist constructivism" correlates the emergence of ethnicity with the movement towards nation states beginning in the early modern period. Proponents of this theory, such as Eric Hobsbawm, argue that ethnicity and notions of ethnic pride, such as nationalism, are purely modern inventions, appearing only in the modern period of world history. They hold that prior to this ethnic homogeneity was not considered an ideal or necessary factor in the forging of large-scale societies.

Ethnicity is an important means by which people may identify with a larger group. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf, do not consider ethnic identity to be universal. They regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups. The process that results in emergence of such identification is called ethnogenesis. Members of an ethnic group, on the whole, claim cultural continuities over time, although historians and cultural anthropologists have documented that many of the values, practices, and norms that imply continuity with the past are of relatively recent invention.

Ethnic groups can form a cultural mosaic in a society. That could be in a city like New York City or Trieste, but also the fallen monarchy of the Austro-Hungarian Empire or the United States. Current topics are in particular social and cultural differentiation, multilingualism, competing identity offers, multiple cultural identities and the formation of Salad bowl and melting pot.Ethnic groups differ from other social groups, such as subcultures, interest groups or social classes, because they emerge and change over historical periods (centuries) in a process known as ethnogenesis, a period of several generations of endogamy resulting in common ancestry (which is then sometimes cast in terms of a mythological narrative of a founding figure); ethnic identity is reinforced by reference to "boundary markers" – characteristics said to be unique to the group which set it apart from other groups.

Ethnicity theory in the United States

Ethnicity theory argues that race is a social category and is only one of several factors in determining ethnicity. Other criteria include "religion, language, 'customs', nationality, and political identification". This theory was put forward by sociologist Robert E. Park in the 1920s. It is based on the notion of "culture".

This theory was preceded by more than 100 years during which biological essentialism was the dominant paradigm on race. Biological essentialism is the belief that some races, specifically White Europeans in western versions of the paradigm, are biologically superior and other races, specifically non-White races in western debates, are inherently inferior. This view arose as a way to justify enslavement of African Americans and genocide of Native Americans in a society that was officially founded on freedom for all. This was a notion that developed slowly and came to be a preoccupation with scientists, theologians, and the public. Religious institutions asked questions about whether there had been multiple creations of races (polygenesis) and whether God had created lesser races. Many of the foremost scientists of the time took up the idea of racial difference and found that White Europeans were superior.

The ethnicity theory was based on the assimilation model. Park outlined four steps to assimilation: contact, conflict, accommodation, and assimilation. Instead of attributing the marginalized status of people of color in the United States to their inherent biological inferiority, he attributed it to their failure to assimilate into American culture. They could become equal if they abandoned their inferior cultures.

Michael Omi and Howard Winant's theory of racial formation directly confronts both the premises and the practices of ethnicity theory. They argue in Racial Formation in the United States that the ethnicity theory was exclusively based on the immigration patterns of the White population and did take into account the unique experiences of non-Whites in the United States. While Park's theory identified different stages in the immigration process – contact, conflict, struggle, and as the last and best response, assimilation – it did so only for White communities. The ethnicity paradigm neglected the ways in which race can complicate a community's interactions with social and political structures, especially upon contact.

Assimilation – shedding the particular qualities of a native culture for the purpose of blending in with a host culture – did not work for some groups as a response to racism and discrimination, though it did for others. Once the legal barriers to achieving equality had been dismantled, the problem of racism became the sole responsibility of already disadvantaged communities. It was assumed that if a Black or Latino community was not "making it" by the standards that had been set by Whites, it was because that community did not hold the right values or beliefs, or were stubbornly resisting dominant norms because they did not want to fit in. Omi and Winant's critique of ethnicity theory explains how looking to cultural defect as the source of inequality ignores the "concrete sociopolitical dynamics within which racial phenomena operate in the U.S." It prevents critical examination of the structural components of racism and encourages a "benign neglect" of social inequality.

Ethnicity and nationality

In some cases, especially those involving transnational migration or colonial expansion, ethnicity is linked to nationality. Anthropologists and historians, following the modernist understanding of ethnicity as proposed by Ernest Gellner and Benedict Anderson see nations and nationalism as developing with the rise of the modern state system in the 17th century. They culminated in the rise of "nation-states" in which the presumptive boundaries of the nation coincided (or ideally coincided) with state boundaries. Thus, in the West, the notion of ethnicity, like race and nation, developed in the context of European colonial expansion, when mercantilism and capitalism were promoting global movements of populations at the same time that state boundaries were being more clearly and rigidly defined.

In the 19th century, modern states generally sought legitimacy through their claim to represent "nations". Nation-states, however, invariably include populations who have been excluded from national life for one reason or another. Members of excluded groups, consequently, will either demand inclusion based on equality or seek autonomy, sometimes even to the extent of complete political separation in their nation-state. Under these conditions when people moved from one state to another, or one state conquered or colonized peoples beyond its national boundaries – ethnic groups were formed by people who identified with one nation but lived in another state.

Multi-ethnic states can be the result of two opposite events, either the recent creation of state borders at variance with traditional tribal territories, or the recent immigration of ethnic minorities into a former nation-state. Examples for the first case are found throughout Africa, where countries created during decolonization inherited arbitrary colonial borders, but also in European countries such as Belgium or United Kingdom. Examples for the second case are countries such as Netherlands, which were relatively ethnically homogeneous when they attained statehood but have received significant immigration in the 17th century and even more so in the second half of the 20th century. States such as the United Kingdom, France and Switzerland comprised distinct ethnic groups from their formation and have likewise experienced substantial immigration, resulting in what has been termed "multicultural" societies, especially in large cities.

The states of the New World were multi-ethnic from the onset, as they were formed as colonies imposed on existing indigenous populations.

In recent decades, feminist scholars (most notably Nira Yuval-Davis) have drawn attention to the fundamental ways in which women participate in the creation and reproduction of ethnic and national categories. Though these categories are usually discussed as belonging to the public, political sphere, they are upheld within the private, family sphere to a great extent. It is here that women act not just as biological reproducers but also as "cultural carriers", transmitting knowledge and enforcing behaviors that belong to a specific collectivity. Women also often play a significant symbolic role in conceptions of nation or ethnicity, for example in the notion that "women and children" constitute the kernel of a nation which must be defended in times of conflict, or in iconic figures such as Britannia or Marianne.

Ethnicity and race

Ethnicity is used as a matter of cultural identity of a group, often based on shared ancestry, language, and cultural traditions, while race is applied as a taxonomic grouping, based on physical similarities among groups. Race is a more controversial subject than ethnicity, due to common political use of the term. Ramón Grosfoguel (University of California, Berkeley) argues that "racial/ethnic identity" is one concept and concepts of race and ethnicity cannot be used as separate and autonomous categories.

Before Weber (1864–1920), race and ethnicity were primarily seen as two aspects of the same thing. Around 1900 and before, the primordialist understanding of ethnicity predominated: cultural differences between peoples were seen as being the result of inherited traits and tendencies. With Weber's introduction of the idea of ethnicity as a social construct, race and ethnicity became more divided from each other.

In 1950, the UNESCO statement "The Race Question", signed by some of the internationally renowned scholars of the time (including Ashley Montagu, Claude Lévi-Strauss, Gunnar Myrdal, Julian Huxley, etc.), said:

National, religious, geographic, linguistic and cultural groups do not necessarily coincide with racial groups: and the cultural traits of such groups have no demonstrated genetic connection with racial traits. Because serious errors of this kind are habitually committed when the term "race" is used in popular parlance, it would be better when speaking of human races to drop the term "race" altogether and speak of "ethnic groups".

In 1982, anthropologist David Craig Griffith summed up forty years of ethnographic research, arguing that racial and ethnic categories are symbolic markers for different ways people from different parts of the world have been incorporated into a global economy:

The opposing interests that divide the working classes are further reinforced through appeals to "racial" and "ethnic" distinctions. Such appeals serve to allocate different categories of workers to rungs on the scale of labor markets, relegating stigmatized populations to the lower levels and insulating the higher echelons from competition from below. Capitalism did not create all the distinctions of ethnicity and race that function to set off categories of workers from one another. It is, nevertheless, the process of labor mobilization under capitalism that imparts to these distinctions their effective values.

According to Wolf, racial categories were constructed and incorporated during the period of European mercantile expansion, and ethnic groupings during the period of capitalist expansion.

Writing in 1977 about the usage of the term "ethnic" in the ordinary language of Great Britain and the United States, Wallman noted

The term "ethnic" popularly connotes "[race]" in Britain, only less precisely, and with a lighter value load. In North America, by contrast, "[race]" most commonly means color, and "ethnics" are the descendants of relatively recent immigrants from non-English-speaking countries. "[Ethnic]" is not a noun in Britain. In effect there are no "ethnics"; there are only "ethnic relations".

In the U.S., the OMB says the definition of race as used for the purposes of the US Census is not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference".

Ethno-national conflict

Sometimes ethnic groups are subject to prejudicial attitudes and actions by the state or its constituents. In the 20th century, people began to argue that conflicts among ethnic groups or between members of an ethnic group and the state can and should be resolved in one of two ways. Some, like Jürgen Habermas and Bruce Barry, have argued that the legitimacy of modern states must be based on a notion of political rights of autonomous individual subjects. According to this view, the state should not acknowledge ethnic, national or racial identity but rather instead enforce political and legal equality of all individuals. Others, like Charles Taylor and Will Kymlicka, argue that the notion of the autonomous individual is itself a cultural construct. According to this view, states must recognize ethnic identity and develop processes through which the particular needs of ethnic groups can be accommodated within the boundaries of the nation-state.

The 19th century saw the development of the political ideology of ethnic nationalism, when the concept of race was tied to nationalism, first by German theorists including Johann Gottfried von Herder. Instances of societies focusing on ethnic ties, arguably to the exclusion of history or historical context, have resulted in the justification of nationalist goals. Two periods frequently cited as examples of this are the 19th-century consolidation and expansion of the German Empire and the 20th century Nazi Germany. Each promoted the pan-ethnic idea that these governments were acquiring only lands that had always been inhabited by ethnic Germans. The history of late-comers to the nation-state model, such as those arising in the Near East and south-eastern Europe out of the dissolution of the Ottoman and Austro-Hungarian Empires, as well as those arising out of the USSR, is marked by inter-ethnic conflicts. Such conflicts usually occur within multi-ethnic states, as opposed to between them, as in other regions of the world. Thus, the conflicts are often misleadingly labeled and characterized as civil wars when they are inter-ethnic conflicts in a multi-ethnic state.

Ethnic groups by continent

Africa

Ethnic groups in Africa number in the hundreds, each generally having its own language (or dialect of a language) and culture.

Asia

Assyrians are one of the indigenous peoples of Northern Iraq.

Ethnic groups are abundant throughout Asia, with adaptations to the climate zones of Asia, which can be the Arctic, subarctic, temperate, subtropical or tropical. The ethnic groups have adapted to mountains, deserts, grasslands, and forests.

On the coasts of Asia, the ethnic groups have adopted various methods of harvest and transport. Some groups are primarily hunter-gatherers, some practice transhumance (nomadic lifestyle), others have been agrarian/rural for millennia and others becoming industrial/urban. Some groups/countries of Asia are completely urban, such as those in Hong Kong, Shanghai, and Singapore. The colonization of Asia was largely ended in the 20th century, with national drives for independence and self-determination across the continent.

In Indonesia alone, there are more than 600 ethnic groups, which are located on 17,000 islands in the Indonesian archipelago.

Russia has more than 185 recognized ethnic groups besides the eighty percent ethnic Russian majority. The largest group is the Tatars, 3.8 percent. Many of the smaller groups are found in the Asian part of Russia (see Indigenous peoples of Siberia).

Europe

Europe has a large number of ethnic groups; Pan and Pfeil (2004) count 87 distinct "peoples of Europe", of which 33 form the majority population in at least one sovereign state, while the remaining 54 constitute ethnic minorities within every state they inhabit (although they may form local regional majorities within a sub-national entity). The total number of national minority populations in Europe is estimated at 105 million people or 14% of 770 million Europeans.

A number of European countries, including France and Switzerland, do not collect information on the ethnicity of their resident population.

An example of a largely nomadic ethnic group in Europe is the Roma, pejoratively known as Gypsies. They originated from India and speak the Romani language.

The Serbian province of Vojvodina is recognizable for its multi-ethnic and multi-cultural identity. There are some 26 ethnic groups in the province, and six languages are in official use by the provincial administration.

North America

The indigenous people in North America are Native Americans. During European colonization, Europeans arrived in North America. Most Native Americans died due to Spanish diseases and other European diseases such as smallpox during the European colonization of the Americas. The largest pan-ethnic group in the United States is White Americans. Hispanic and Latino Americans (Mexican Americans in particular) and Asian Americans have immigrated to the United States recently. In Mexico, most Mexicans are mestizo, a mixture of Spanish and Native American ancestry. Some Hispanic and Latino Americans living in the United States are not mestizos.

Enslaved Africans were brought to North America from the 16th to 19th centuries during the Atlantic slave trade. Many of them were sent to the Caribbean. Ethnic groups that live in the Caribbean are: indigenous peoples, Africans, Indians, White Europeans, Chinese and Portuguese. The first White Europeans to arrive in the Dominican Republic were the Spanish in 1492. The Caribbean was also colonized and discovered by the Portuguese, English, Dutch and French.

A sizeable number of people in the United States have mixed-race identities. In 2021, the number of Americans who identified as non-Hispanic and more than one race was 13.5 million. The number of Hispanic Americans who identified as multiracial was 20.3 million. Over the course of the 2010s decade, there was a 127% increase in non-Hispanic Americans who identified as multiracial.

The largest ethnic groups in the United States are Germans, African Americans, Mexicans, Irish, English, Americans, Italians, Poles, French, Scottish, Native Americans, Puerto Ricans, Norwegians, Dutch people, Swedish people, Chinese people, West Indians, Russians and Filipinos.

In Canada, European Canadians are the largest ethnic group. In Canada, the indigenous population is growing faster than the non-indigenous population. Most immigrants in Canada come from Asia.

South America

In South America, although highly varying between regions, people are commonly mixed-race, indigenous, European, black African, and to a lesser extent also Asian.

Oceania

Nearly all states in Oceania have majority indigenous populations, with notable exceptions being Australia, New Zealand and Norfolk Island, who have majority European populations. States with smaller European populations include Guam, Hawaii and New Caledonia (whose Europeans are known as Caldoche). Indigenous peoples of Oceania are Australian Aboriginals, Austronesians and Papuans, and they originated from Asia. The Austronesians of Oceania are further broken up into three distinct groups; Melanesians, Micronesians and Polynesians.

Oceanic South Pacific islands nearing Latin America were uninhabited when discovered by Europeans in the 16th century, with nothing to indicate prehistoric human activity by Indigenous peoples of the Americas or Oceania. Contemporary residents are mainly mestizos and Europeans from the Latin American countries whom administer them, although none of these islands have extensive populations. Easter Island are the only oceanic island politically associated with Latin America to have an indigenous population, the Polynesian Rapa Nui people. Their current inhabitants include indigenous Polynesians and mestizo settlers from political administrators Chile, in addition to mixed-race individuals with Polynesian and mestizo/European ancestry. The British overseas territory of Pitcairn Islands, to the west of Easter Island, have a population of approximately 50 people. They are mixed-race Euronesians who descended from an initial group of British and Tahitian settlers in the 18th century. The islands were previously inhabited by Polynesians; they had long abandoned Pitcairn by the time the settlers had arrived. Norfolk Island, now an external territory of Australia, is also believed to have been inhabited by Polynesians prior to its initial European discovery in the 18th century. Some of their residents are descended from mixed-race Pitcairn Islanders that were relocated onto Norfolk due to overpopulation in 1856.

The once uninhabited Bonin Islands, later politically integrated into Japan, have a small population consisting of Japanese mainlanders and descendants of early European settlers. Archeological findings from the 1990s suggested there was possible prehistoric human activity by Micronesians prior to European discovery in the 16th century.

Several political entities associated with Oceania are still uninhabited, including Baker Island, Clipperton Island, Howland Island and Jarvis Island. There were brief attempts to settle Clipperton with Mexicans and Jarvis with Native Hawaiians in the early 20th century. The Jarvis settlers were relocated from the island due to Japanese advancements during World War II, while most of the settlers on Clipperton ended up dying from starvation and murdering one and other.

Australia

The first evident ethnic group to live in Australia were the Australian Aboriginals, a group considered related to the Melanesian Torres Strait Islander people. Europeans, primarily from England, arrived first in 1770.

The 2016 Census shows England and New Zealand are the next most common countries of birth after Australia. The proportion of people born in China and India has increased since 2011 (from 6.0 per cent to 8.3 per cent, and 5.6 per cent to 7.4 per cent, respectively).

The proportion of people identifying as being of Aboriginal or Torres Strait Islander origin increased from 2.5 per cent of the Australian population in 2011 to 2.8 per cent in 2016.

Avian influenza

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Avian_influenza

Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.

Symptoms of avian influenza vary according to both the strain of virus underlying the infection, and on the species of bird or mammal affected. Classification of a virus strain as either low pathogenic avian influenza (LPAI) or high pathogenic avian influenza (HPAI) is based on the severity of symptoms in domestic chickens and does not predict severity of symptoms in other species. Chickens infected with LPAI display mild symptoms or are asymptomatic, whereas HPAI causes serious breathing difficulties, significant drop in egg production, and sudden death. Domestic poultry may potentially be protected from specific strains of the virus by vaccination.

Humans and other mammals can only become infected with avian influenza after prolonged close contact with infected birds. In mammals including humans, infection with avian influenza (whether LPAI or HPAI) is rare. Symptoms of infection vary from mild to severe, including fever, diarrhea, and cough.

Influenza A virus is shed in the saliva, mucus, and feces of infected birds; other infected animals may shed bird flu viruses in respiratory secretions and other body fluids (e.g., cow milk). The virus can spread rapidly through poultry flocks and among wild birds. A particularly virulent strain, influenza A virus subtype H5N1 (A/H5N1) has the potential to decimate domesticated poultry stocks and an estimated half a billion farmed birds have been slaughtered in efforts to contain the virus.

Highly pathogenic avian influenza

Because of the impact of avian influenza on economically important chicken farms, a classification system was devised in 1981 which divided avian virus strains as either highly pathogenic (and therefore potentially requiring vigorous control measures) or low pathogenic. The test for this is based solely on the effect on chickens – a virus strain is highly pathogenic avian influenza (HPAI) if 75% or more of chickens die after being deliberately infected with it. The alternative classification is low pathogenic avian influenza (LPAI). This classification system has since been modified to take into account the structure of the virus' haemagglutinin protein. Other species of birds, especially water birds, can become infected with HPAI virus without experiencing severe symptoms and can spread the infection over large distances; the exact symptoms depend on the species of bird and the strain of virus. Classification of an avian virus strain as HPAI or LPAI does not predict how serious the disease might be if it infects humans or other mammals.

Since 2006, the World Organization for Animal Health requires all LPAI H5 and H7 detections to be reported because of their potential to mutate into highly pathogenic strains.

Virology

Avian influenza is caused by the influenza A virus which principally affects birds but can also infect humans and other mammals.Influenza A is an RNA virus with a genome comprising a negative-sense, RNA segmented genome that encodes for 11 viral genes. The virus particle (also called the virion) is 80–120 nanometers in diameter and elliptical or filamentous in shape. There is evidence that the virus can survive for long periods in freshwater after being excreted in feces by its avian host, and can withstand prolonged freezing.

There are two proteins on the surface of the viral envelope; hemagglutinin and neuraminidase. These are the major antigens of the virus against which neutralizing antibodies are produced. Influenza virus epidemics and epizootics are associated with changes in their antigenic structure.

Hemagglutinin (H) is an antigenic glycoprotein which allows the virus to bind to and enter the host cell. Neuraminidase (N) is an antigenic glycosylated enzyme which facilitates the release of progeny viruses from infected cells. There are 18 known types of hemagglutinin, of which H1 thru H16 have been found in birds, and 11 types of neuraminidase.

Subtypes

Subtypes of influenza A are defined by the combination of H and N proteins in the viral envelope; for example, "H5N1" designates an influenza A subtype that has a type-5 hemagglutinin (H) protein and a type-1 neuraminidase (N) protein. The subtyping scheme only takes into account the two envelope proteins, not the other proteins coded by the virus' RNA. Almost all possible combinations of H (1 thru 16) and N (1 thru 11) have been isolated from wild birds. Further variations exist within the subtypes and can lead to very significant differences in the virus's ability to infect and cause disease.

Influenza virus nomenclature

To unambiguously describe a specific isolate of virus, researchers use the internationally accepted Influenza virus nomenclature, which describes, among other things, the species of animal from which the virus was isolated, and the place and year of collection. As an example, A/chicken/Nakorn-Patom/Thailand/CU-K2/04(H5N1):

A stands for the genus of influenza (A, B or C)
chicken is the animal species the isolate was found in (note: human isolates lack this component term and are thus identified as human isolates by default)
Nakorn-Patom/Thailand is the place this specific virus was isolated
CU-K2 is the laboratory reference number that identifies it from other influenza viruses isolated at the same place and year
04 represents the year of isolation 2004
H5 stands for the fifth of several known types of the protein hemagglutinin
N1 stands for the first of several known types of the protein neuraminidase.

Other examples include: A/duck/Hong Kong/308/78(H5N3), A/avian/NY/01(H5N2), A/chicken/Mexico/31381-3/94(H5N2), and A/shoveler/Egypt/03(H5N2).

Genetic characterization

Analysis of the virus' genome enables researchers to determine the order of its nucleotides. Comparison of the genome of a virus with that of a different virus can reveal differences between the two viruses. Genetic variations are important because they can change amino acids that make up the influenza virus’ proteins, resulting in structural changes to the proteins, and thereby altering properties of the virus. Some of these properties include the ability to evade immunity and the ability to cause severe disease.

Genetic sequencing enables influenza strains to be further characterised by their clade or subclade, revealing links between different samples of virus and tracing the evolution of the virus over time.

Species barrier

Humans can become infected by the avian flu if they are in close contact with infected birds. Symptoms vary from mild to severe (including death), but as of December 2024 there have been no observed instances of sustained human-human transmission.

There are a number of factors that generally prevent avian influenza viruses from causing epidemics in humans or other mammals.

The viral HA protein of avian influenza binds to alpha-2,3 sialic acid receptors, which are present in the respiratory tract and intestines of avian species, while human influenza HA binds to alpha-2,6 sialic acid receptors, which are present in the human upper respiratory tract.
The myxovirus resistance protein (Mx1) is an important antiviral restriction factor that inhibits the replication of avian influenza viruses in particular. Human-adapted strains of IAV display reduced sensitivity to human Mx1 compared with avian strains.
Other factors include the ability to replicate the viral RNA genome within the host cell nucleus, and to transmit between individuals.

Influenza viruses are constantly changing as small genetic mutations accumulate, a process known as antigenic drift. Over time, mutation may lead to a change in antigenic properties such that host antibodies (acquired through vaccination or prior infection) do not provide effective protection, causing a fresh outbreak of disease.

The segmented genome of influenza viruses facilitates genetic reassortment. This can occur if a host is infected simultaneously with two different strains of influenza virus; then it is possible for the viruses to interchange genetic material as they reproduce in the host cells. Thus, an avian influenza virus can acquire characteristics, such as the ability to infect humans, from a different virus strain. The presence of both alpha 2,3 and alpha 2,6 sialic acid receptors in pig tissues allows for co-infection by avian influenza and human influenza viruses. This susceptibility makes pigs a potential "melting pot" for the reassortment of influenza A viruses.

Epidemiology

History

Avian influenza (historically known as fowl plague) is caused by bird-adapted strains of the influenza type A virus. The disease was first identified by Edoardo Perroncito in 1878 when it was differentiated from other diseases that caused high mortality rates in birds; in 1955 it was established that the fowl plague virus was closely related to human influenza. In 1972, it became evident that many subtypes of avian flu were endemic in wild bird populations.

Between 1959 and 1995, there were 15 recorded outbreaks of highly pathogenic avian influenza (HPAI) in poultry, with losses varying from a few birds on a single farm to many millions. Between 1996 and 2008, HPAI outbreaks in poultry have been recorded at least 11 times and 4 of these outbreaks have resulted in the death or culling of millions of birds. Since then, several virus strains (both LPAI and HPAI) have become endemic among wild birds with increasingly frequent outbreaks among domestic poultry, especially of the H5 and H7 subtypes.

Transmission and prevention

Birds – Influenza A viruses of various subtypes have a large reservoir in wild waterbirds of the orders Anseriformes (for example, ducks, geese, and swans) and Charadriiformes (for example, gulls, terns, and waders) which can infect the respiratory and gastrointestinal tract without affecting the health of the host. They can then be carried by the bird over large distances, especially during annual migration. Infected birds can shed avian influenza A viruses in their saliva, nasal secretions, and feces; susceptible birds become infected when they have contact with the virus as it is shed by infected birds. The virus can survive for long periods in water and at low temperatures, and can be spread from one farm to another on farm equipment. Domesticated birds (chickens, turkeys, ducks, etc.) may become infected with avian influenza A viruses through direct contact with infected waterfowl or other infected poultry, or through contact with contaminated feces or surfaces.

Avian influenza outbreaks in domesticated birds are of concern for several reasons. There is potential for low pathogenic avian influenza viruses (LPAI) to evolve into strains which are high pathogenic to poultry (HPAI), and subsequent potential for significant illness and death among poultry during outbreaks. Because of this, international regulations state that any detection of H5 or H7 subtypes (regardless of their pathogenicity) must be notified to the appropriate authority. It is also possible that avian influenza viruses could be transmitted to humans and other animals which have been exposed to infected birds, causing infection with unpredictable but sometimes fatal consequences.

When an HPAI infection is detected in poultry, it is normal to cull infected animals and those nearby in an effort to rapidly contain, control and eradicate the disease. This is done together with movement restrictions, improved hygiene and biosecurity, and enhanced surveillance.

Humans – Avian flu viruses, both HPAI and LPAI, can infect humans who are in close, unprotected contact with infected poultry. Incidents of cross-species transmission are rare, with symptoms ranging in severity from no symptoms or mild illness, to severe disease that resulted in death. As of February, 2024 there have been very few instances of human-to-human transmission, and each outbreak has been limited to a few people. All subtypes of avian Influenza A have potential to cross the species barrier, with H5N1 and H7N9 considered the biggest threats.

In order to avoid infection, the general public are advised to avoid contact with sick birds or potentially contaminated material such as carcasses or feces. People working with birds, such as conservationists or poultry workers, are advised to wear appropriate personal protection equipment.

Other animals – a wide range of other animals have been affected by avian flu, generally due to eating birds which had been infected. There have been instances where transmission of the disease between mammals, including seals and cows, may have occurred.

Pandemic potential

Influenza viruses have a relatively high mutation rate that is characteristic of RNA viruses. The segmentation of the influenza A virus genome facilitates genetic recombination by segment reassortment in hosts who become infected with two different strains of influenza viruses at the same time. With reassortment between strains, an avian strain which does not affect humans may acquire characteristics from a different strain which enable it to infect and pass between humans – a zoonotic event. It is thought that all influenza A viruses causing outbreaks or pandemics among humans since the 1900s originated from strains circulating in wild aquatic birds through reassortment with other influenza strains. It is possible (though not certain) that pigs may act as an intermediate host for reassortment.

As of June 2024, there is concern about two subtypes of avian influenza which are circulating in wild bird populations worldwide, H5N1 and H7N9. Both of these have potential to devastate poultry stocks, and both have jumped to humans with relatively high case fatality rates.

Surveillance

The Global Influenza Surveillance and Response System (GISRS) is a global network of laboratories that monitor the spread of influenza with the aim to provide the World Health Organization with influenza control information and to inform vaccine development. Several millions of specimens are tested by the GISRS network annually through a network of laboratories in 127 countries. As well as human viruses, GISRS monitors avian, swine, and other potentially zoonotic influenza viruses.

Vaccine

Poultry – it is possible to vaccinate poultry against specific strains of HPAI influenza. Vaccination should be combined with other control measures such as infection monitoring, early detection and biosecurity.

Humans – Several "candidate vaccines" are available in case an avian virus acquires the ability to infect and transmit among humans. There are strategic stockpiles of vaccines against the H5N1 subtype, which is considered the biggest risk. A vaccine against the H7N9 subtype, which has also infected humans, has undergone a limited amount of testing. In the event of an outbreak, the "candidate" vaccine would be rapidly tested for safety as well as efficacy against the zoonotic strain, and then authorised and distributed to vaccine manufacturers.

Zoonotic influenza vaccine Seqirus is authorized for use in the European Union. It is an H5N8 vaccine that is intended to provide acquired immunity against H5 subtype influenza A viruses.

Influenza A virus subtype H5N1

The highly pathogenic influenza A virus subtype H5N1 is an emerging avian influenza virus that is causing global concern as a potential pandemic threat. It is often referred to simply as "bird flu" or "avian influenza", even though it is only one of many subtypes.

A/H5N1 has killed millions of poultry in a growing number of countries throughout Asia, Europe, and Africa. Health experts are concerned that the coexistence of human flu viruses and avian flu viruses (especially H5N1) will provide an opportunity for genetic material to be exchanged between species-specific viruses, possibly creating a new virulent influenza strain that is easily transmissible and lethal to humans.

Influenza A/H5N1 was first recorded in a small outbreak among poultry in Scotland in 1959, with numerous outbreaks subsequently in every continent. The first known transmission of A/H5N1 to a human occurred in Hong Kong in 1997, when there was an outbreak of 18 human cases resulting in 6 deaths. It was determined that all the infected people had been exposed to infected birds in poultry markets. As the disease continued to spread among poultry flocks in the territory, the decision was made to cull all 1.6 million poultry in the area and to impose strict controls on the movement and handling of poultry. This terminated the outbreak.

There is weak evidence to support limited human-to-human transmission of A/H5N1 in 139 outbreaks between 2005 and 2009 in Sumatra. The reproduction number was well below the threshold for sustained transmission.

Between 2003 and December 2024, the World Health Organization has recorded 963 cases of confirmed H5N1 influenza, leading to 465 deaths. The true fatality rate may be lower because some cases with mild symptoms may not have been identified as H5N1.

Influenza A virus subtype H7N9

A significant outbreak of influenza A virus subtype H7N9 (A/H7N9) started in March 2013 when severe influenza affected 18 humans in China; six subsequently died. It was discovered that a low pathogenic strain of A/H7N9 was circulating among chickens, and that all the affected people had been exposed in poultry markets. Further cases among humans and poultry in mainland China continued to be identified sporadically throughout the year, followed by a peak around the festival season of Chinese New Year (January and February) in early 2014 which was attributed to the seasonal surge in poultry production. Up to December 2013, there had been 139 cases with 47 deaths.

Infections among humans and poultry continued during the next few years, again with peaks around the new year. In 2016 a virus strain emerged which was highly pathogenic to chickens. In order to contain the HPAI outbreak, the Chinese authorities in 2017 initiated a large scale vaccination campaign against avian influenza in poultry. Since then, the number of outbreaks in poultry, as well as the number of human cases, dropped significantly. In humans, symptoms and mortality for both LPAI and HPAI strains have been similar. Although no human H7N9 infections have been reported since February 2019, the virus is still circulating in poultry, particularly in laying hens. It has demonstrated antigenic drift to evade vaccines, and remains a potential threat to the poultry industry and public health.

Genetic and evolutionary analyses have shown that the A(H7) viruses in the Chinese outbreak probably transferred from domestic duck to chicken populations in China and then reassorted with poultry influenza A(H9N2) to generate the influenza A(H7N9) strain that affected humans. The genetic characteristics of A(H7N9) virus are of concern because of their pandemic potential, e.g. their potential to recognise human and avian influenza virus receptors which affects the ability to cause sustained human-to-human transmission, or the ability to replicate in the human host.

Between February 2013 and February 2019, there were 1,568 confirmed human cases and 616 deaths associated with the outbreak in China. The majority of human cases have reported contact with poultry in markets or farms. Transmission between humans remains limited with some evidence of small family clusters. However, there is no evidence of sustained human-to-human transmission of A/H7N9 influenza.

During early 2017, outbreaks of avian influenza A(H7N9) occurred in poultry in the USA. The strain in these outbreaks was of North American origin and is unrelated to the Asian lineage H7N9 which is associated with human infections in China.

Domestic animals

Several domestic species have been infected with and shown symptoms of H5N1 viral infection, including cats, dogs, ferrets, pigs, and birds.

Poultry

Attempts are made in the United States to minimize the presence of HPAI in poultry through routine surveillance of poultry flocks in commercial poultry operations. Detection of a HPAI virus may result in immediate culling of the flock. Less pathogenic viruses are controlled by vaccination.

Dairy cows

During April 2024, avian influenza was first detected in dairy cows in several US states and subsequently spread more widely through the year. Influenza A(H5N1) was found to be present at high levels in the mammary glands and in the milk of affected cows. It was shown that the virus can persist on milking equipment, which provides a probable transmission route for cow-to-cow and cow-to-human spread. A number of humans who had been in contact with cows tested positive for the virus, with mild symptoms. According to CDC, 7% of 115 dairy workers had evidence of recent infection in a study from Michigan and Colorado from June to August 2024 – half of them asymptomatic. This is higher than estimates from prior transmission studies in poultry. All dairy workers had worked in cleaning the milk parlor and none had used personal protective equipment.

Cats

Cats with avian influenza exhibit symptoms that can result in death. The avian influenza viruses cats may get include H5N1 or H7N2, notable pathogenic subtypes of the virus. In order to get the virus, a cat would need to be in contact with infected waterfowl, poultry, or uncooked poultry. Two of the main organs that the virus affects are the lungs and liver.

Global aspects

Global measures

In 2005, the formation of the International Partnership on Avian and Pandemic Influenza was announced in order to elevate the importance of avian flu, coordinate efforts, and improve disease reporting and surveillance in order to better respond to future pandemics. New networks of laboratories have emerged to detect and respond to avian flu, such as the Crisis Management Center for Animal Health, the Global Avian Influenza Network for Surveillance, OFFLU, and the Global Early Warning System for major animal diseases. After the 2003 outbreak, WHO member states have also recognized the need for more transparent and equitable sharing of vaccines and other benefits from these networks. Cooperative measures created in response to HPAI have served as a basis for programs related to other emerging and re-emerging infectious diseases.

Impact on national policies

HPAI control has also been used for political ends. In Indonesia, negotiations with global response networks were used to recentralize power and funding to the Ministry of Health. In Vietnam, policymakers, with the support of the Food and Agriculture Organization of the United Nations (FAO), used HPAI control to accelerate the industrialization of livestock production for export by proposing to increase the portion of large-scale commercial farms and reducing the number of poultry keepers from 8 to 2 million by 2010.

Traditional Asian practices

Backyard poultry production was viewed as "traditional Asian" agricultural practices that contrasted with modern commercial poultry production and seen as a threat to biosecurity. Backyard production appeared to hold greater risk than commercial production due to lack of biosecurity and close contact with humans, though HPAI spread in intensively raised flocks was greater due to high density rearing and genetic homogeneity. Asian culture itself was blamed as the reason why certain interventions, such as those that only looked at placed-based interventions, would fail without looking for multifaceted solutions.

Economic impact

Approximately 20% of the protein consumed in developing countries come from poultry. A report by FAO totalled economic losses caused by avian influenza in South East Asia up to 2005 around US$10 billion. This had the greatest impact on small scale commercial and backyard producers.

As poultry serves as a source of food security and liquid assets, the most vulnerable populations were poor, small scale farmers. The loss of birds due to HPAI and culling in Vietnam led to an average loss of 2.3 months of production and US$69–108 for households where many have an income of $2 a day or less. The loss of food security for vulnerable households can be seen in the stunting of children under five in Egypt. Women are another population at risk as in most regions of the world, small flocks are tended to by women. Widespread culling also resulted in the decreased enrollment of girls in school in Turkey.
