We still have no word on the subtype of either of the two suspected avian flu samples collected two days ago (see Media: Japan Testing Dead Birds In Hokkaido & Akita Prefectures), however, we have an update from Japan's Ministry of the Environment indicating a second bird has died and tested positive at the Akita Zoo, and a media report stating a cull has been ordered.

Normally we'd anticipate either H5N1 or H5N8 in this part of the world, but recent reports of HPAI H5N6 appearing in South Korea for the very first time (see FAO Notification Of HPAI H5N6 In South Korea) add yet another possibility.
