This study describes the national program of year-round surveillance and monitoring for avian influenza (AI). The validity of the epidemiologically-based surveillance scheme was assessed. Korea’s current surveillance program is aimed at detecting subclinical infection of either the highly pathogenic avian influenza (HPAI) virus or the low pathogenic avian influenza virus, types H5 and H7, both of which carry risk of converting to HPAI. The current AI surveillance program has demonstrated that implementing a surveillance strategy is plausible. Farmer and livestock related professional support is the critical step of specimen collection to discover hidden infection. Early detection of AI virus infection can achieve best by the combined efforts of farmers, animal health authorities, and other related industries.
