The most widely quoted date for the beginning of the recorded history of avian influenza (AI) is 1878, when researchers first differentiated a disease of poultry (initially known as fowl plague but later renamed highly pathogenic avian influenza) from other diseases with high mortality rates. Current evidence indicates that highly pathogenic AI (HPAI) viruses arise through mutation after low pathogenicity AI viruses of H5 or H7 subtype are introduced into poultry. Between 1877 and 1958, a…

The transmission of H5 and H7 low pathogenic avian influenza viruses

It can be suggested that the risk of a wild bird originated LPNAIV becoming established in poultry is only realistic if the virus itself has a high infectious potential to poultry.

A brief history of bird flu

The genesis of novel influenza A virus strains by reassortment and evolution in wild and domestic bird populations, as well as the role of wild bird migration in their long-range spread are described.

Mapping the risk of avian influenza in wild birds in the US

22 species of song birds and perching birds (order Passeriformes) are influenza reservoirs in the contiguous US and the regression model identifies the Great Plains and the Pacific Northwest as high-risk areas for AIV.

H7N7 Avian Influenza Virus Mutation from Low to High Pathogenicity on a Layer Chicken Farm in the UK

Clinical, epidemiological, and virological investigations for the H7N7 UK HPAIV outbreak on a farm with layer chickens in mixed free-range and caged units document the identification of a LPAIV to HPAiv mutation in nature, providing insights into factors that drive its manifestation during outbreaks.

Molecular Surveillance of Avian Influenza in Live Bird Market of Qom City in Iran

Live Bird Markets (LBM) are hypothesized to be a missing link in the epidemiology of AIV and it is important that the LBMs be routinely monitored for AIV.

The emergence and diversification of panzootic H5N1 influenza viruses.

Prevalence and control of H7 avian influenza viruses in birds and humans

This review summarizes the emergence of avian influenza virus H7 subtypes in birds and humans, and the possibilities of its control in poultry.

JMM Profile: Avian influenza: a veterinary pathogen with zoonotic potential.

Both LPAIV and HPAIV H5 and H7 AIV subtypes are classified as the causative agents of notifiable disease in poultry and the close proximity between mammalian and susceptible avian species in some environments provides the opportunity for both inter-host transmission and mammalian adaptation.

Emergence and Evolution of Avian H5N2 Influenza Viruses in Chickens in Taiwan

The findings suggest that reassortant H5N2 viruses, together with H6N1 viruses, have become established and enzootic in chickens throughout Taiwan and that a large-scale vaccination program might have been conducted locally that likely led to the introduction of the 1994 Mexican-like virus to Taiwan in 2003.

The surveillance and risk assessment of wild birds in northern Australia for highly pathogenic avian influenza H5N1 virus

The evaluation of a commercial NP c-ELISA, HI test, Taqman Type A RRT-PCR and embryonating chicken egg (ECE) virus isolation methods suggests high validity of these tests in wild birds, comparable to that reported in poultry.



Origin and evolution of highly pathogenic H5N1 avian influenza in Asia

The H5N1 viruses have reportedly been eliminated from three of the nine countries that reported disease in 2003/04, but they could be extremely difficult to eradicate from the remaining countries, owing to the existence of populations and, possibly, production and marketing sectors, in which apparently normal birds harbour the viruses.

Epidemiology and ecology of highly pathogenic avian influenza with particular emphasis on South East Asia.

Although there are some questions that remain unanswered regarding the origins of the 2004 outbreaks, the current understanding of the ecology and epidemiology of the disease should lead to the development of adapted targeted surveillance studies and control strategies.

A review of avian influenza in different bird species.

Should We Change the Definition of Avian Influenza for Eradication Purposes?

The accumulating evidence is that HPAI viruses arise from low-pathogenicity avian influenza (LPAI) H5 or H7 viruses infecting chickens and turkeys after spread from free-living birds, which may require redefining statutory AI.

The avian influenza epidemic in Italy, 1999—2000: A review

A reconsideration of current European legislation and a reorganization of the poultry industry are suggested to prevent the occurrence of similar situations in countries of the European Union.

Avian influenza: recent developments

The human health implications have now gained importance, both for illness and fatalities that have occurred following natural infection with avian viruses, and for the potential of generating a reassortant virus that could give rise to the next human influenza pandemic.

Avian influenza A subtype H9N2 in poultry in Pakistan

The poultry industry of Pakistan is still at a developmental stage, and about 80% of the breeding stocks are reared in the northern hilly areas of the country, where the ambient temperatures range from 2 to 25°C, compared with the high summer temperature ranges of 35 to 45°C.

Avian influenza viruses and human health.

There have been regular reports of natural infections of humans with avian influenza viruses: in England in 1996 (H7N7), Hong Kong 1997 (H5N1), 1999 (H9N2), and 2003 (H3N2) and Thailand 2004 (H 5N1); the H5N 1 virus is alarming because 51 of the 80 people confirmed as infected since 1997 have died.

Recombination Resulting in Virulence Shift in Avian Influenza Outbreak, Chile

Sequence analysis of all eight genes of the LPAI virus and the HPAI viruses showed minor differences between the viruses except at the hemagglutinin (HA) cleavage site, which indicates a virulence shift.

It is demonstrated that H5N1 influenza viruses, isolated from apparently healthy domestic ducks in mainland China from 1999 through 2002, were becoming progressively more pathogenic for mammals, and a hypothesis explaining the mechanism is presented.
