The Central Disaster and Safety Countermeasure Headquarters in South Korea is strengthening quarantine measures at poultry farms due to the first case of highly pathogenic avian influenza in Japan this winter. The strain in Japan is the H5N1 type, similar to one found in Korea in October. The Korean government is implementing stricter inspections, education, and surveillance, particularly in areas where wild birds migrate. Farmers are advised to report any symptoms in their poultry and strictly follow quarantine rules.
