Abstrakt: The article presents a study on the endemic status of highly pathogenic influenza H5N1 virus in wildlife in the Lake Qinghai area of northwest China. For the study, researchers initiated a continuous surveillance scheme from September 2005 to September 2007. They gathered 2,699 field samples in which 95 were found to be positive of the virus through a reverse transcription-polymerase chain reaction (RT-PCR) test of subtype H5 influenza virus. They found two 2007 isolates manifested more similarities of the hemagglutinin and neuraminidase genes with those of the 2005 and 2006 isolates.
