Serological evidence of hepatitis E virus and influenza A virus infection in farmed wild boars in China

Abstract Hepatitis E virus (HEV) and influenza A virus (IAV) are two important pathogens which can infect humans and various animals causing public health problems. In this study, the seroprevalence and risk factors associated with HEV and IAV infection in farmed wild boars were investigated in China. A total of 758 serum samples were collected from farmed wild boars between 2015 and 2016, and antibodies against HEV and IAV were examined by enzyme-linked immunosorbent assay (ELISA) using commercially available kits. The overall prevalence of anti-HEV antibodies was 24.54% (186/758, 95% CI 21.48–27.60) in farmed wild boars. There were statistically significant differences in the HEV seroprevalence in farmed wild boars of different ages ( 66 days: 26.36%) ( P P
