Epidemiological comments
Cases in wild birds : Wakayama-City 1; A dead Aix galericulata(Mandarin Duck) was collected on 3 December 2020 and tested against avian influenza virus. The Tottori University conducted RT-PCR and gene sequencing tests and confirmed that the subtype of the virus was H5N8. Yakage-Town 1; A dead Falco peregrinus (Peregrine Falcon) was collected on 4 December 2020 and tested against avian influenza virus. The Tottori University conducted RT-PCR and gene sequencing tests and confirmed that the subtype of the virus was H5N8. Mitoyo-City 1; A dead Buteo japonicus (Eastern buzzard) was collected on 8 December 2020 and tested against avian influenza virus. The Tottori University conducted RT-PCR and gene sequencing tests and confirmed that the subtype of the virus was H5N8. Izumi-City 1 ; A dead Grus monacha (Hooded crane) was collected on 18 December 2020 and tested against avian influenza virus. The Kagoshima University conducted RT-PCR and gene sequencing tests and confirmed that the subtype of the virus was H5N8. Enhanced monitoring of wild birds is ongoing within a 10 kilometer radius around the sites.
