Serological prevalence of avian H۹N۲ influenza virus in dogs by hemagglutination inhibition assay in Kerman, southeast of Iran

Influenza is a highly contagious zoonotic disease in the world. Avian H۹N۲ influenza virus is a significant pandemic pathogen widely distributed throughout the world. Pet ownership has been documented as a risk factor for infection transmission to human. Considering major public health concern, the prevalence of antibodies against avian H۹N۲ influenza virus was evaluated in ۱۷۰ serum samples of dogs by hemagglutination inhibition assay. This study is the first survey to assess the epidemiology of avian H۹N۲ influenza virus infection in dogs in Kerman, southeast of Iran. Out of ۱۷۰ samples, ۶۵ (۳۸.۲۳%) were positive for H۹N۲. Antibodies were higher in farm dogs that were kept with other animals and also in dogs were fed a raw diet. These findings emphasize the importance of close attention to these populations for control and prevention programs. It is important to reduce infection burden, especially in regions with widespread distribution of H۹N۲.
