[h=4]Volume 21, Number 7?July 2015[/h] [h=4]Letter[/h] [h=1]Seropositivity for Avian Influenza H6 Virus among Humans, China[/h]
To the Editor: Influenza virus subtype H6 was first isolated from a turkey in 1965 in the United States (1) and was subsequently found in other parts of the world (2). Over the past several decades, the prevalence of H6 virus has dramatically increased in wild and domestic birds (2?4). In China, highly pathogenic influenza A(H5N1), low pathogenicity influenza (H9N2), and H6 are the most prevalent avian influenza viruses among poultry (5). Although only 1 case of H6 virus infection in a human has been reported worldwide (6), several biological characteristics of H6 viruses indicate that they are highly infectious to mammals. Approximately 34% of H6 viruses circulating in China have enhanced affinity to human-like receptors (ɑ-2,6 NeuAcGal) (2). H6 viruses can also infect mice without prior adaptation (2,7), and some H6 viruses can be transmitted efficiently among guinea pigs (2). To evaluate the potential threat of H6 viruses to human health, we conducted a systematic serologic study in populations occupationally exposed to H6 viruses.
