As part of the USA's National Strategy for Pandemic Influenza, an Interagency Strategic Plan for the Early Detection of Highly Pathogenic H5N1 Avian Influenza in Wild Migratory Birds was developed and implemented. From 1 April 2006 through 31 March 2009, 261,946 samples from wild birds and 101,457 wild bird fecal samples were collected in the USA; no highly pathogenic avian influenza was detected. The United States Department of Agriculture, and state and tribal cooperators accounted for 213… Expand
Molecular Surveillance of Low Pathogenic Avian Influenza Viruses in Wild Birds across the United States: Inferences from the Hemagglutinin Gene
TLDR
This study confirms intercontinental exchange of some HA subtypes (including a newly documented H9 exchange event), as well as identifies subtypes that do not regularly experience intercontinental gene flow but have been circulating and evolving in North America for at least the past 20 years. Expand
Large-Scale Avian Influenza Surveillance in Wild Birds throughout the United States
TLDR
A large-scale, interagency surveillance effort to determine if highly pathogenic avian influenza viruses were present in wild bird populations within the United States of America, combined with the Canadian and Mexican surveillance programs, represented the largest, coordinated wildlife disease surveillance program ever implemented. Expand
Detection of avian influenza viruses in wild waterbirds in the Rift Valley of Kenya using fecal sampling.
TLDR
The results of a wild bird surveillance system for A/H5N1 and other avian influenza viruses based on avian fecal sampling in Kenya demonstrates the success of this approach in detectingAvian influenza virus in wild birds and represents an efficient surveillance system in regions with limited resources. Expand
Risk of spill-over of diseases (in particular avian influenza) from wild aquatic birds in North Queensland
TLDR
Avian influenza antibodies were at higher levels during warm wet weather (January-April) compared with warm dry weather (September-December) in linear regression analysis (Coefficient 8.3; 95% Confidence interval 3.0-13.6) and this analysis indicated that immature birds were more commonly infected which may be due to the fact that they have more frequent infections because they are immunologically naive whereas adults are more resistant to viruses.

Surveillance of Influenza A Virus and Its Subtypes in Migratory Wild Birds of Nepal
TLDR
This study provides baseline data on the status of avian influenza virus in migratory bird populations in Nepal and finds influenza A H9N2 was found in one sample from a ruddy shelduck in Koshi Tappu Wildlife Reserve located in southern Nepal. Expand
Identification of Type A Influenza Viruses from Wild Birds on the Delmarva Peninsula, 2007–10
SUMMARY Wild waterfowl and shorebirds in the Delaware-Maryland-Virginia (Delmarva) Peninsula region within the Atlantic Flyway were sampled as part of the Early Detection of Highly Pathogenic H5N1Expand
NO EVIDENCE OF INFECTION OR EXPOSURE TO HIGHLY PATHOGENIC AVIAN INFLUENZAS IN PERIDOMESTIC WILDLIFE ON AN AFFECTED POULTRY FACILITY
TLDR
Preliminary data suggesting that peridomestic wildlife were not an important factor in the transmission of Aiv during the poultry outbreak, nor did small birds and mammals in natural wetland settings show wide evidence of AIV shedding or exposure, despite the opportunity for exposure, are provided. Expand
Experimental infections of Norway rats with avian-derived low-pathogenic influenza A viruses
TLDR
This study further characterize IAV infection in Norway rats using IAV strains derived from poultry and wild water birds and confirmed all animals were confirmed to be seronegative. Expand
Sampling Strategies and Biodiversity of Influenza A Subtypes in Wild Birds
TLDR
This study identifies a sampling methodology that will detect an estimated 75% of circulating virus subtypes from a targeted bird population and outlines future surveillance and research priorities that are needed to explore the influence of host and virus biodiversity on emergence and transmission. Expand
Identification of high risk areas for avian influenza outbreaks in California using disease distribution models
TLDR
This study provides further insights into the spatial epidemiology of AI in California, and the high spatial resolution maps may be useful to guide risk-based surveillance and outreach efforts. Expand

Low Pathogenicity Avian Influenza Subtypes Isolated from Wild Birds in the United States, 2006–2008
TLDR
The majority (59%) of all wild bird samples was collected from dabbling ducks, and 91% of H5 detections using real-time reverse transcriptase polymerase chain reaction (rRT-PCR) were in dabbling Ducks, which was the most prevalent subtype. Expand
Guidelines on wild bird surveillance for highly pathogenic avian influenza H5N1 virus
TLDR
A valuable wildlife surveillance program based on ecological and epidemiological information will require large-scale collaboration among national governments and ministries, multilateral agencies, nongovernment organizations, academicians, veterinarians, virologists, ornithologists, and many others.

TLDR
One isolate from sentinel ducks - A/duck/Potsdam/81 (Hav8 Nav5) - had an hitherto undescribed combination of the surface antigens, which is possible to recognize epidemics among wild birds by sentinels and by periodic serological observations of wild pelagic bird populations. Expand
Predicting the global spread of H5N1 avian influenza
TLDR
H5N1 is more likely to be introduced into the Western Hemisphere through infected poultry and into the mainland United States by subsequent movement of migrating birds from neighboring countries, rather than from eastern Siberia. Expand
Influenza in Migratory Birds and Evidence of Limited Intercontinental Virus Exchange
TLDR
Overall, the available evidence does not support the perpetuation of HP H5N1 influenza in migratory birds and suggests that the introduction of HP Asian H 5N1 to the Americas by migratoryirds is likely to be a rare event. Expand
Matrix Gene of Influenza A Viruses Isolated from Wild Aquatic Birds: Ecology and Emergence of Influenza A Viruses
TLDR
The hypothesis that influenza viruses in wild waterfowl contain distinguishable lineages of M genes is supported by phylogenetic analysis of 70 matrix genes of influenza viruses isolated from shorebirds and gulls in the Delaware Bay region and from ducks in Alberta, Canada during >18 years of surveillance. Expand
Molecular Epidemiologic Studies on North American H9 Avian Influenza Virus Isolates from Waterfowl and Shorebirds
TLDR
Positive evolutionary selection was observed for the HA gene among the North American waterfowl and shorebird H 9N2 viruses, indicating that the H9N2-type viruses are changing in their natural hosts. Expand
Recent expansion of highly pathogenic avian influenza H5N1: a critical review
TLDR
A critical examination of the arguments both for and against the role of migratory birds in the global dispersal of HPAI H5N1 concludes that, whilst wild birds undoubtedly contribute to the local spread of the virus in the wild, human activities including farming, and marketing of poultry also contribute.

Reemerging H5N1 Influenza Viruses in Hong Kong in 2002 Are Highly Pathogenic to Ducks
TLDR
Despite a high level of genomic homology, the human isolate showed striking biological differences from its avian homologue in a duck model, suggesting that significant antigenic variation has recently occurred among H5N1 viruses. Expand
Molecular analysis of highly pathogenic avian influenza virus of subtype H5N1 isolated from wild birds and mammals in northern Germany.
TLDR
Phylogenetic analyses of the HA and neuraminidase nucleotide sequences showed that avian influenza H5N1 isolates from the Astrakhan region located in southern Russia were the closest relatives and reassortment events could be excluded in comparison with other 'Qinghai-like' H 5N1 viruses. Expand
