| 【 要旨 】 | E型肝炎ウィルス (HEV) は人獣共通感染症で，ブタ，イノシシ，シカに感染が確認されている．本邦の海外渡航歴のないE型肝炎例のうち，イノシシ肉や内臓を食した後に発症したE型肝炎例が散見され，イノシシ肉 (内臓) からの経口感染はHEVの重要な感染経路と考えられる．発症例は中高年の男に多い．本州，九州，四国でHEV-RNA陽性のイノシシが証明され，どの地方でもイノシシ肉や内臓の生食はHEV感染の危険があると考えられる．また，急性肝炎診察時には野生動物の肉，内臓の摂取歴を聞く習慣をつけることが重要である． | |

| [ Summary ] | Zoonotic transmission of the hepatitis E virus (HEV) has been reported. The significance of wild boars as a source of HEV infection was reviewed. The number of Japanese patients with acute hepatitis E, including fulminant hepatitis who had a history of eating wild boar meat, including liver, has totaled four. Several investigators have studied the prevalence of anti-HEV and HEV-RNA in wild boars, and found that HEV-RNA was present in several % of wild boars. Boars positive for HEV-RNA were found in the Kyushu, Shikoku and Honshu areas in Japan. From these reports, wild boars have been identified as an important source of zoonotic HEV transmission. | |
