The first A/H10N8 virus was isolated from a duck in Guangdong province, China, in 2012.[2] The virus shows high pathogenicity in mice. It was also found in waterfowls, feral dogs, and live poultry markets. While multiple H10 genotype viruses (e.g. H10N8, H10N3, and H10N7) are circulating in live poultry markets in China, their potential to infect mammals remains largely unknown.[2]
