A serological survey on hema2glutination inhibition (HI) antibodies against egg drop syndrome-1976 (EDS-76) virus was made among domestic birds and wild birds in Taiwan between 1978 and 1984. No antibody was detected in the chicken sera collected in 1978 and sera of turkeys and wild birds collected in 1984. However. HI antibodies were demonstrated in sera from chicken collected in 1980(73%) and 1982 (30.2%). Hence it is suspected that the virus was introduced into chicken flocks in Taiwan between 1978 and 1980. In addition .HI antibodies were demonstrated in sera from domestic ducks (313%) and gesese (11.4%) collected in 1980.
