The avian influenza virus detected at a poultry farm in Kagoshima Prefecture was found to be a highly lethal, highly pathogenic "H5N1 type" by analysis by a national research institute.
It is a different type from the virus detected at poultry farms in Akita Prefecture, and experts say that the virus was introduced by multiple routes along the route of migratory birds, and prepare for the spread of infection all over the country. I am appealing for the need.
Avian influenza virus was detected in chickens at a chicken farm in Izumi City, Kagoshima Prefecture on the 13th of this month, and when a national research institute investigated it in detail, it was confirmed to be highly pathogenic "H5N1 type".
According to the Ministry of Agriculture, Forestry and Fisheries, the H5N1 virus has been found in quails and wild birds in Europe as well as in Germany and the United Kingdom since last month, accounting for nearly 80% of the bird flu reported worldwide this season. It means that it is.
On the other hand, at a poultry farm in Yokote City, Akita Prefecture, the same highly pathogenic "H5N8 type" virus that caused the largest-ever spread of infection in Japan was detected this month and last season.
Professor Yoshihiro Sakoda of Hokkaido University, who is familiar with bird flu, said, "It is thought that different types of viruses were brought in at the same time along the route of migratory birds. We need to have a system. "
