South Korea, which has been battling HPAI H5N6 since it arrived last November, has also reported a small number of H5N8 detections (primarily in wild birds) this winter as well. Over the past 90 days, South Korea has lost more than 33 million birds to the H5N6 virus, or to culling - twice what they lost during 2014's H5N8 epizootic.
While avian flu reports have slowed coming out of Korea over recent weeks, today MAFRA reports the detection of H5N8 at a duck farm in Haenam County, in South Jeolla Province. At the same time they are investigating a suspected AI outbreak among hens at a farm in Chungnam, Cheongyang.
Although H5N6 has appeared to run roughshod over H5N8 in both Japan and South Korea since it arrived last fall, evidence suggests that H5N8 continues to circulate in the region. According to MAFRA, 10 of 59 wild bird AI detections (17%) this winter have been H5N8, while the remainder (83%) have been H5N6.
