Hepatitis E Virus and Toxoplasma Gondii in Wild Boars from Southern Kyushu, Japan.

This study investigated the seroprevalence of zoonotic hepatitis E virus and Toxoplasma gondii (T. gondii) in wild boars from southern Kyushu, Japan, from 2014 to 2021, including increased hunting until 2015. The seroprevalence was 16.38% for hepatitis E virus (n = 116; 95% CI 10.74-24.17) and 12.40% for T. gondii (n = 130; 95% CI 7.78-19.20). A decreasing trend for hepatitis E virus was observed (P = 0.05777). As the first study on wild boars in southern Kyushu, it provides insights into hepatitis E virus and T. gondii epidemiology, suggesting that managing boar density could help control diseases.
