The purcxse of this surveillance was to reali epklemiology of avian influenza in Taiwan wild birds and pcultry. fri 2005, a total of 4,5% fftai samples from wild birds were exarnino-J. Fcxrty-nine viruses were isolatl and subtyt1 as H1N1, H2N7, H3N6, H3N8, H3NQ,H4N2, H4N3, H4N6, H5N2, H6N1, HIN3, H1ON6, H1ON8, H 11 N9 and Hi 2N2. Most of these viruses were isolael from ckc]c faoai samples; but two viruses, H3N8 and H4N6, were isolael from terns. In addition, S strains of H’7N3 and 1 strain of HSN2 viruses were isoiael from the wild dwzks inTaireiandTainan, and all of those viruses were low ethogenic (U>) stains. In pcniitry surveillance, 2,613 samples coileced from chicken farms, except one LP HSN2 virus isolati from 30 sentinel chickens in a cleaance fami, no any H5 c- H? avian influenza virus was ckte*%d in other farms.

In our conclusion, Taiwan is still a HSN1 -fie country. There was no evi&nce of HSN1 virus carri&J by the entry migiay birds. So that, the risk of this virus invai3e nto Taiwan by migxatcy birds is very low.
