Japan’s Ministry of the Environment announced on October 30 that researchers at Hokkaido University had recently discovered the H5N8 highly pathogenic avian influenza virus in the feces of wild birds in Hokkaido.
A related report issued by the Japanese Ministry of the Environment on the same day stated that researchers collected wild bird feces samples in Monbetsu City, Hokkaido on the 24th, and the test results on the 30th confirmed the presence of H5N8 avian influenza virus. This is the first time a highly pathogenic avian influenza virus has been detected in wild bird droppings in Japan after about two and a half years. The Ministry of the Environment has designated 10 kilometers around the sample collection site as a key area for wild bird surveillance.
Since the beginning of this year, Slovakia, Saudi Arabia, Russia, Kazakhstan and other countries have reported outbreaks of H5N8 avian influenza in their borders. South Korean authorities collected wild bird feces in Cheonan City, Chungcheongnam-do on October 21, and reported on the 25th that H5N8 avian influenza virus was detected.
H5N8 avian influenza virus is a highly infectious virus between birds. Since the H5N8 avian influenza virus was first discovered in 2014, no cases of human infection with this virus have been found.
