While less traveled than its H5N8 and H5N1 cousins, H5N6 made its big breakout from China last fall, and over the past 12 months has visited Japan, South Korea, Taiwan and the Philippines. Unlike H5N8, H5N6 has a limited history of infecting - and killing - humans.
H5N6 also continues to evolve, and reassort, at an impressive rate (see Virology: Five Distinct Reassortants of HPAI H5N6 In Japan - Winter 2016–2017), and there are genuine concerns that it may eventually spread globally via migratory birds as have H5N8 and H5N1.Today's announcement will no doubt heighten the alert level - not only in Japan - but all up and down the Asian Migratory flyway.
