EPIDEMIOLOGICAL COMMENTS
The outbreak of Saiki-City1 (H5N2 Case1 / HPAI Case60): On 16 January 2023, a Livestock Hygiene Service Centre (LHSC) in Oita Prefecture received a notification from a domestic broiler farm on an increase in the number of dead birds. The samples were collected from dead birds in the farm by prefectural veterinary officers and tested positive for influenza A virus by viral antigen rapid test. On 17, the LHSC conducted RT-PCR and RRT-PCR tests and confirmed that the subtype was H5. On the same day, stamping-out of all birds in the affected farm (12,900 birds) and 2 epidemiologically linked farms (42,500 birds) was completed. On 18, relevant control measures were completed. On 19, the National Institute of Animal Health (NIAH) conducted the sequencing and confirmed that the subtype of the virus was H5N2 and the causative virus was determined as high pathogenicity avian influenza. Movement restriction and shipment restriction are imposed on farms within a radius of 3 km and 10 km of the affected farms respectively.
