This case is the 34th occurrence of highly pathogenic avian influenza at poultry farms in the 2025–2026 winter season.

Highly pathogenic avian influenza at poultry farms occurred 22 times in Dec. last year and six times in Jan. this year, and it has spread to 20 cities and counties in six provinces and metropolitan cities, making additional outbreaks highly likely.

To detect infected ducks early, the headquarters said it will conduct simultaneous precision testing at breeder duck farms and hatcheries nationwide.
