Abstract
Water bodies are important media for the spread and transmission of avian influenza viruses (AIV). The determining factor for an AIV to transmit through diffusion in waters is the term of viability of the virus in water body. To better understand the perpetuation of AIV in nature waters, and thus risks of AIV spread and transmission via it, we systematically studied the inactivation dynamics of two strains (H5N1 and H9N2), at different temperatures in waters of important migratory birds habitats within China: Dongting Lake, Poyang Lake, Qinghai Lake and Hubei segment of the Yangtze River, and we also studied the impact of water-borne microorganisms on perpetuation of AIVs. Our findings indicate that water is very likely an important route for the epidemic spread of the AIVs, especially during the fall and winter seasons. In addition, water-borne microorganisms significantly antagonize the persistence of AIVs.
