Research Abstract

In this study, the infection experiment supposing various infection routes of highly pathogenic avian influenza virus in field was conducted.
The results obtained showed that (1) the virus spreads from infected wild waterfowl to terrestrial wild bird through the water of lake
(2) the infected terrestrial wild bird invades in a henhouse, and a virus spreads by contacting with a chicken
but (3) between terrestrial wild birds, it is hard to consider a possibility that infection will spread one after another.
These results support the notion that the invasion preventive measures of the terrestrial wild bird into a henhouse are very important on the epidemic prevention of highly pathogenic avian influenza avian influenza.
