Japan: Poultry Outbreak Identified As HPAI H5N6

Kagawa Prefecture - Credit Wikipedia
















#13,060


Although it really comes as no surprise - given the recent environmental bird flu test results in Japan and poultry AI outbreaks in South Korea - today we have confirmation from Japan's MAFF (Ministry of Agriculture, Forestry & Fisheries) that their first poultry outbreak of this winter has tested out as HPAI H5N6
This is presumably the same new lineage H5N6 that has been identified in Asia and parts of Western Europe the past two months, that rose from a reassortment of the European H5N8 virus (see Tottori University: Shimane HPAI H5N6 A New Reassortment).


If any significant changes have occurred, I'm sure we'll hear about it in the next week or so.  Here is today's (translated) announcement:.
