Japan and South Korea - both of which lie beneath the East Asian-Australian Migratory Flyway - continue to report HPAI H5 (mostly H5N8) detections in wild birds & environmental samples, and - in the case of Japan - outbreaks on multiple poultry farms (see here, here, and here).
This year's resurgence in avian flu - both in Asia and Europe - is the strongest showing we've seen since the winter of 2016-2017.
Five days ago, in Japan: 2nd Outbreak Of HPAI H5 In Poultry, we looked at the second outbreak in three days in Kagawa Prefecture. Since then Japan has reported two more outbreaks on farms in Kagawa Prefecture, and one environmental detection in Kagoshima Prefecture which is located at the southernmost point of Kyūshū.
The two latest outbreak reports from Japan's Ministry of Environment.
November 13, 2nd year of Reiwa
Confirmation of pseudo-patients with highly pathogenic avian influenza in Kagawa Prefecture (4th domestic poultry case)
On November 13, 2nd year of Reiwa, there was a report that a pseudo-patient with highly pathogenic avian influenza, which was the fourth case in Japan for poultry, was confirmed at a beef cattle farm in Mitoyo City, Kagawa Prefecture. In response to this report, we will strengthen the monitoring of wild birds by designating the area within a radius of 10 km around the outbreak farm as a priority area for wild bird monitoring.
1. 1. Background
Friday, November 6th~ November 8th (Sun) ・ Kagawa Prefecture entered all farms except the vacant farms in the surrounding farms due to the first outbreak of poultry farming in Japan ( November 5), and conducted genetic tests and antibody tests. Confirmed negative of the chickens raised at the chicken farm.
Thursday, November 12
・ Kagawa Prefecture conducted an on-site inspection of the farm after receiving a report that the number of dead chickens had increased.
・ On the same day, a simple influenza test was conducted on the chicken and the result was positive.
Friday, November 13 ・ As a result of genetic testing of the chicken, it was confirmed that it was a H5 subtype and was a pseudo-patient with highly pathogenic avian influenza.
Confirmation of pseudo-patients with highly pathogenic avian influenza in Kagawa Prefecture
On November 11, 2nd year of Reiwa, it was reported that a pseudo-patient with highly pathogenic avian influenza, which was the third case in Japan for poultry, was confirmed at a beef cattle farm in Mitoyo City, Kagawa Prefecture. The farm is located within a 3km radius of the city's poultry farm, where the highly pathogenic avian influenza (first case in Japan this year) broke out on November 5. In response to this report, we will strengthen the monitoring of wild birds by designating the area within a radius of 10 km around the outbreak farm as a priority area for wild bird monitoring.

Wednesday, November 11 ・ As a result of genetic testing of the chicken, it was confirmed that it was a H5 subtype and was a pseudo-patient with highly pathogenic avian influenza.
And the second environmental detection of HPAI H5, this time in Kagoshima Prefecture.
Highly pathogenic avian influenza virus test positive in water collected in Kagoshima prefecture (second case in wild birds)
A highly pathogenic avian influenza virus (H5 subtype) was detected (positive) in an environmental sample (water) collected in Izumi City, Kagoshima Prefecture on November 9 (Monday) by a test conducted by Kagoshima University. There was a report. In response to this report, we will strengthen the monitoring of wild birds by designating the area within 10 km around the collection point as a priority area for wild bird monitoring.
The Environmental detection in Kagoshima Prefecture (Izumi City) is of particular concern because that is the home of a major overwintering spot for thousands of rare Hooded, and White-naped cranes, which are considered national treasures in Japan.
Like the Mission San Juan Capistrano’s annual return of the swallows, Izumi City on the southern tip of Japan celebrates the yearly arrival these rare a vulnerable cranes. A decade ago they were threatened by the arrival of H5N1 (see Japan’s Bird Flu Dilemma), and in 2016 they had a brief brush with HPAI H5N6.
