Seroprevalance and Identification of Influenza A Virus Infection from Migratory Wild Waterfowl in China (2004–2005)
Summary Outbreaks of a highly pathogenic avian influenza (H5N1) were reported in birds in more than eight Asian countries.

| Summary: | Summary Outbreaks of a highly pathogenic avian influenza (H5N1) were reported in birds in more than eight Asian countries. We sought to identify the origin of this infection, and herein report the results of serological and virological monitoring of migrant wild waterfowl in mainland China. From a total of 493 serum samples, collected from 15 migratory wild waterfowl species for 9 months (from June 2004 to May 2005) in mainland China, we detected only low‐level antibodies against influenza subtypes H2, H9 and H10 in the relict gull, little egret, black‐crowned night heron, bar‐tailed godwit, whimbrel and the common greenshank. No virus was identified from the 1052 cloacal and oropharyngeal swabs except dead bar‐headed geese. These data show that the influenza type A virus subtypes H2–H13 did not circulate at detectable levels within the sampled population. |
