| 1 | Surveillance for highly pathogenic avian influenza in wild birds in the USA显示文摘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.From1April2006 through 31 March 2009,261946 samples fromwild birds and 101457 wild bird fecalsamples 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 213115(81%)of the wild bird samples collected;31,27,21 and 21%of the samples were collected from theAtlantic,Pacific,Central and Mississippi flyways,respectively.More than 250 species of wild birds in all 50 states were sampled.The majority of wild birds(86%)were dabbling ducks,geese,swans and shorebirds.The apparent prevalence of low pathogenic avian influenza viruses during biological years 2007 and 2008 was 9.7 and 11.0%,respectively.The apparent prevalence of H5 and H7 subtypes across all species sampled were 0.5 and 0.06%,respectively.The pooled fecal samples(n=101539)positive for low pathogenic avian influenza were 4.0,6.7 and 4.7%for biological years 2006,2007 and 2008,respectively.The highly pathogenic early detection system for wild birds developed and implemented in the USA represents the largest coordinated wildlife disease surveillance system ever conducted.This effort provided evidence that wild birds in the USA were free of highly pathogenic avian influenza virus(given the expected minimum prevalence of 0.001%)at the 99.9%confidence level during the surveillance period. | Thomas J.DELIBERTO Seth R.SWAFFORD Dale L.NOLTE Kerri PEDERSEN Mark W.LUTMAN Brandon B.SCHMIT John A.BAROCH Dennis J.KOHLER Alan FRANKLIN | 2009 | Integrative Zoology2009，4，4： | 0 |
