A study on the seroprevalence of VHDV antibodies in rabbits in 5 different regions of Central and South-Eastern parts of Poland was undertaken. A total of 2180 samples of sera collected from animals small private farms were tested. Out of 630 examined samples of sera from large farms, 270 were taken from rabbits older than 2-months born from seropositive dams. The VHDV antibodies were recorded in 138 (6.3%) samples of sera with the level of various provinces of Poland from 3 to 11.2 %. We found out that the presence of the seropositive animals was due to VHDV infection as well as the prophylactic vaccination employed during the last years.
