EPIDEMIOLOGICAL COMMENTS

This is the first report of highly pathogenic avian influenza H5N5 in mammals in Canada. We previously reported wild birds with wholly Eurasian H5N5 from Prince Edward Island and New Brunswick (event 4754). We are now reporting two raccoons from Prince Edward Island found dead. The geographical marker is on the capital. For both raccoons, the virus contains wholly Eurasian genome segments. For detailed and current information on high pathogenicity avian influenza cases in wildlife, please consult : http://www.cwhc-rcsf.ca/avian_influenza.php.
