Water bodies are an important route for the spread and transmission of avian influenza virus (AIV). The determining factor for an AIV to transmit through diffusion in water is the term of viability of the virus in the water body. To better understand the perpetuation of AIV in natural water bodies, and thus the risks of AIV spread and transmission via such bodies, we systematically studied the inactivation dynamics of two AIV strains (H5N1 and H9N2) at different temperatures in water bodies of important migratory bird habitats within China (Dongting Lake, Poyang Lake, the Hubei segment of the Yangtze River and Qinghai Lake). We also studied the impact of water-borne micro-organisms on the perpetuation of AIV. Our findings indicated that water is very likely an important route for the epidemic spread of AIV, especially during the autumn and winter seasons. In addition, water-borne micro-organisms might antagonize the persistence of AIV.

D005585	Influenza in Birds	Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D053124	Influenza A Virus, H5N1 Subtype	A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 5 and neuraminidase 1. The H5N1 subtype, frequently referred to as the bird flu virus, is endemic in wild birds and very contagious among both domestic (POULTRY) and wild birds. It does not usually infect humans, but some cases have been reported.	H5N1 Avian Influenza Virus,H5N1 Bird Flu Virus,H5N1 Virus,H5N1 subtype,H5N1 Viruses,H5N1 subtypes,Virus, H5N1
