Abstract

In April 2020, two Whooper Swans (Cygnus cygnus) and one Swan Goose (Anser cygnoides) were found dead at three different locations in western Mongolia. Virus isolation from organs taken from the carcasses and full genome sequencing revealed that all three birds were positive for highly pathogenic H5N6 avian influenza virus (HPAIV) belonging to subclade 2.3.4.4h. Confirming similar reports from central Mongolia and western China, these findings have important implications for the monitoring, control, and management of HPAIVs in wild bird and commercial poultry populations in Mongolia.
