High hepatitis E virus antibody positive rates in dogs and humans exposed to dogs in the south ‐west of China

The objective of this study was to investigate the prevalence of HEV infection among dogs and humans exposed to dogs in the south‐west region of China. A total of 4,490 dog serum samples and 2,206 relative practitioner serum samples were collected from 18 pet hospitals and dog farms in Yunnan, Sichuan and Guizhou province, and the anti‐HEV IgG antibodies were detected by ELISA. The results showed that the total positive rate of anti‐HEV antibodies was 36.55% with the highest rate in city stray dogs, and the differences in distinct species and growth phases were significant. The positive rate of anti‐HEV antibody in veterinarian and farm staff‐related practitioners was significantly higher than the general population. The finding of the present survey suggested that high HEV seroprevalence in dogs and humans exposed to dogs in the south‐west area of China poses a significant public health concern. It is urgent to improve integrated strategies to detect, prevent and control HEV infection in dogs and humans exposed to dogs in this area.
