The newly detected avian influenza virus at a poultry farm in Kagoshima Prefecture on the 15th was found to be a highly pathogenic "H5N8 type" with a high mortality rate, according to an analysis by a national research institute.
This month, the type is different from the one detected at a nearby poultry farm, and the Ministry of Agriculture, Forestry and Fisheries has called for thorough countermeasures, saying that it is highly possible that the virus was introduced by multiple routes.
In Izumi City, Kagoshima Prefecture, the avian influenza virus was detected in chickens in a poultry farm on the 13th of this month, followed by chickens in another poultry farm about 2.5 km away on the 15th.
Upon closer examination by a national research institute, the virus is the same highly pathogenic "H5N8 type" detected in Yokote City, Akita Prefecture, which is different from the "H5N1 type" detected at a nearby poultry farm. That is.
The Ministry of Agriculture, Forestry and Fisheries has reiterated the possibility that migratory birds have introduced the virus through multiple routes, and is calling for thorough measures such as closing holes for wild animals to invade and disinfecting them.
Professor Yoshihiro Sakoda of Hokkaido University, who is familiar with bird flu, said, "It is easy for viruses to be brought into places where migratory birds gather from all over the world, and different types of viruses may have been detected in a short period of time. It is necessary to take a thorough system, assuming that the damage will exceed last year, which was the largest spread of infection in the past. "
