Figure 1. Global movement of wild birds (adapted from ) and geographic distribution of novel HPAI A(H5N8) viruses, 2016. Influenza A viruses were isolated from wild birds and free-ranging domestic ducks in the Tanguar haor region of Bangladesh (yellow square) during February 2015–February 2016. Dissemination of novel HPAI A(H5N8) clade 184.108.40.206 viruses (red arrows). Dashed circles indicate location of reassortment between HPAI A(H5N8) group B viruses and low pathogenicity avian influenza viruses circulating along the Central Asian flyway. HPAI, highly pathogenic avian influenza.
