Japan's avian epizootic continues to ramp up, with two new poultry farms in Miyazaki Prefecture testing positive, involving over 100,000 birds. The two farms are about 25 km apart, and both are located within 10 km of 3 to 4 million farmed birds raised on dozens of farms.
While avian flu activity globally has been greatly suppressed since the summer of 2017, over the past 90 days we've seen a resurgence - both in Asia and Europe/Russia - along with the emergence of a `genetically distinct' strain of HPAI H5 into Europe (see Pre-Print: Novel Incursion of a HPAI H5N8 Virus in the Netherlands, October 2020).
