Because wild birds can carry Avian Influenza and not appear sick, APHIS works with federal and state partners to conduct surveillance testing on wild birds. These tests tell us whether any highly pathogenic avian influenza (HPAI) viruses are found in the wild bird population. Highly pathogenic avian influenza (HPAI) A(H5N8) viruses that emerged in poultry in east Asia since spread to Europe and North America by late Despite detections in migrating birds, the role of free-living wild birds in the global dispersal of H5N8 virus is by: Waterfowl and shorebirds are considered to be the natural reservoirs for all avian influenza virus subtypes and, in general, most subtypes cause little or no disease in wildlife. However, type A influenza has undergone a combination of genetic drifts and shifts that have resulted in the H5N1 AI virus strain causing morbidity and mortality in many wildlife species. Guidelines on Wild Bird Surveillance for Highly Pathogenic Avian Influenza H5N1 Virus1 Vittorio Guberti2 and Scott H. Newman3,4,5 1 Presentation at the FAO and OIE International Scientific Conference on Avian Influenza and Wild Birds, Rome, 30 and 31 May 2 Istituto Nazionale Fauna Selvatica, Via Ca’ Fornacetta, Ozzano E.

This effort provided evidence that wild birds in the USA were free of highly pathogenic avian influenza virus (given the expected minimum prevalence of %) at the % confidence level during the surveillance period. Key words: disease surveillance, highly pathogenic avian influenza, H5N1, morbidity and mortality, wild by: Surveillance of wild birds for avian influenza viruses has been compulsory in the European Union (EU) since , primarily as a means of detecting H5N1 highly pathogenic avian influenza (HPAI. waterfowl and shorebirds. However, the occurrence of highly pathogenic avian influenza (HPAI) subtype highly pathogenic H5N1 avian influenza has raised concern regarding the potential impact on wild birds, domestic poultry, and human health should it be introduced into the United States (U.S.). However, the nature of research and surveillance efforts directed towards IAVs in wild birds in North America has evolved considerably over the past 50 years, and particularly, since the repeated detection of highly pathogenic (HP) IAVs of Goose/Guangdong (Gs/GD) lineage in wild birds inhabiting Asia, Europe, and Africa beginning shortly after Cited by: 4.
Wild bird surveillance for highly pathogenic avian influenza H5 in North America. It is unknown how the current Asian origin highly pathogenic avian influenza H5 viruses arrived, but these viruses are now poised to become endemic in North America. Wild birds harbor these viruses and have dispersed them at regional scales. Surveillance aiming at the virological detection of highly pathogenic avian influenza (HPAI) in wild birds found dead or moribund (passive surveillance). In addition, some MSs also perform active surveillance by testing living and hunted : Adam Brouwer, Jose Gonzales, Adeline Huneau, Paolo Mulatti, Thijs Kuiken, Christoph Staubach, Arjan. Wild birds of the orders Anseriformes (ducks, geese, and swans) and Charadriiformes (gulls and shorebirds) are believed to be the predominant reservoir for avian influenza viruses (AIVs) (1), and most AIV subtypes are low pathogenicity (LPAIV) (2). Only subtypes H5 and H7 are commonly associated with highly pathogenic AIVs (HPAIVs), Cited by: 8. Plan for Highly Pathogenic Avian Influenza in Waterfowl in the United States outlines the specific wild bird surveillance efforts for Both plans were written by the Interagency Steering Committee for Surveillance for HPAI in Wild Birds. This committee is comprised of experts from USDA-APHIS Wildlife Services and Veterinary Services, U.S.
