[TD]On 10 January 2018, the local veterinary service in Kagawa Prefecture received a notification from a domestic broilers farm on an increase in the number of dead birds (55 birds on the same day). The samples were sent to the laboratory of the local veterinary service (Tobu Livestock Hygiene Service Centre) and the samples from dead birds and live birds were confirmed as avian influenza virus positive by antigen-capture kits. On 11 January, the Centre conducted RT-PCR and RRT-PCR tests and confirmed that the subtype was H5. On 12 January, the sequencing of the H5 gene was carried out by the National Institute of Animal Health (NIAH) and the causative virus was determined as highly pathogenic avian influenza virus. On the same day, NIAH conducted the RT-PCR test and confirmed that the subtype of the virus was H5N6. Stamping-out policy was applied to the affected farm. Destruction of all the susceptible 51000 birds in the affected farm and 40000 birds in an epidemiologically linked farm is being implemented. Movement and shipment restrictions are imposed on the farms within a radius of 3 km and 3-10 km of the affected farm respectively. Full genome sequencing of the virus is undergoing.[/TD]
