Hepatitis E virus (HEV) is an enterically transmitted RNA virus that causes both epidemic and sporadic cases of acute hepatitis. Despite sero-surveys showing antibody to HEV in up to 36% of the US population, acute hepatitis E has been reported among individuals with no history of international travel only three times in the United States. We report a case of apparently locally-acquired hepatitis E that occurred in El Paso, Texas that was 98% similar to a previously isolated HEV found in swine in the United States. Like the three previous cases, a thorough investigation found no conclusive sources of infection. Active case surveillance found no additional cases.
戊型肝炎病毒（HEV）是一种经肠道传播的RNA病毒，可导致急性肝炎的流行和散发病例。尽管血清学调查显示，美国高达36%的人群存在抗HEV抗体，但在美国，仅报告过3例无国际旅行史的急性戊型肝炎病例。我们报告了1例明显在当地感染的戊型肝炎病例，该病例发生在得克萨斯州的埃尔帕索，与之前在美国猪身上分离出的一种HEV有98%的相似性。与之前的3例病例一样，经过全面调查，未发现确凿的感染源。主动病例监测未发现其他病例。
