Korea has confirmed its 12th case of highly pathogenic avian influenza (AI) for the season at a duck farm in the southwestern region, authorities said Wednesday

The latest case was detected at a duck farm in the county of Buan in North Jeolla Province, some 190 kilometers south of Seoul, according to the authorities.

The farm is located in a 10-km radius of another duck farm that reported a highly pathogenic AI case last week.

To prevent further spread, officials have taken measures to control access to the farm to carry out investigations and culled the affected ducks. (Yonhap)
