The tested sera were randomly collected from a total of 1,947 sera from 9 breeding farms unvaccinated in Jeju. As a result, all breeding farms were seropositive for PRRSV. Seven hundred-eighty six of 1,947 sera (40.4%) were positive for PRRSV. Seropositve rate of PRRSV infection in 9 farms showed various levels: 1%, 8.9%, 9.1%, 43%, 46.9%, 48.2%, 51.6%, 60.9%, 85.5%, respectively.
