A serological survey of canine H3N2, pandemic H1N1/09 and human seasonal H3N2 influenza viruses in dogs in China.
Influenza viruses have been isolated from dogs in China; however, the extent of influenza infection among dogs is not yet clear. Here, we examined the seroprevalence of avian-origin canine H3N2, pandemic H1N1/09 and human seasonal H3N2 influenza viruses in pet dogs in China during January 2012 to June 2013. The seropositivity rate of canine H3N2, H1N1/09 and human H3N2 were 3.5%, 1.5%, and 1.2%, respectively. Dogs aged 2-5 years were most commonly seropositive to canine H3N2 virus. It is worth noting that two serum samples were positive against both canine H3N2 and H1N1/09 viruses, suggesting the possibility of coinfection with both viruses. Our findings emphasize the necessity for continued surveillance of influenza viruses in dogs in China.
