Low Pathogenic Avian Influenza A (H5N7) Virus Isolated from a Domestic Duck in Dongting Lake Wetland of China, 2016
The avian influenza virus (AIV) H5N7 was first isolated from wild birds in North America in 2001 (Spackman et al. 2007), and information on only 25 strains of this virus has been deposited in the Global Initiative on Sharing All Influenza Data (GISAID-http://platform.gisaid.org/epi3/frontend#493de3) database until October 30, 2018. Twenty viruses were identified in the United States from 2001 to 2017, three viruses in Denmark in 2003, and two viruses in Mongolia in 2014 (GISAID-http://platform.gisaid.org/epi3/frontend#493de3). All these H5N7 viruses were low pathogenicity and were discovered in wild migratory birds.
Wild migratory birds serve as natural reservoir of AIVs and disseminate the viruses during long-distance migration. Wetlands are important for wild migratory birds as stopover for resting and breeding. In China, millions of domestic ducks are also raised near Dongting Lake Wetland Nature Reverse (Hunan Province Rural Social and Economic Investigation Team 2008)...
