Though Egypt ranks among the top countries for viral hepatitis and death-related liver disease, Hepatitis E virus (HEV) is a neglected pathogen. Living in villages and rural communities with low sanitation, use of underground well water and contact with animals are the main risk factors for HEV infection. Domestic animals, especially ruminants and their edible products, are one source of infection. Contamination of water by either human or animal stools is the main route of infection. In addition, HEV either alone or in coinfection with other hepatotropic viruses has been recorded in Egyptian blood donors. HEV seropositivity among Egyptian villagers was 60-80%, especially in the first decade of life. Though HEV seropositivity is the highest among Egyptians, HEV infection is not routinely diagnosed in Egyptian hospitals. The initial manifestations of HEV among Egyptians is a subclinical infection, although progression to fulminant hepatic failure has been recorded. With the improvement in serological and molecular approaches and increasing research on HEV, it is becoming clear that HEV represents a threat for Egyptians and preventive measures should be considered to reduce the infection rate and possible complications.
尽管埃及在病毒性肝炎和与死亡相关的肝病方面位列全球高发国家,但戊型肝炎病毒(HEV)却是一种被忽视的病原体。生活在卫生条件差的村庄和农村社区、使用地下井水以及与动物接触是戊型肝炎病毒感染的主要风险因素。家畜,尤其是反刍动物及其可食用产品,是感染源之一。人类或动物粪便污染水源是主要感染途径。此外,在埃及献血者中已记录到戊型肝炎病毒单独感染或与其他嗜肝病毒合并感染的情况。埃及村民中的戊型肝炎病毒血清阳性率为60%至80%,尤其是在生命的第一个十年。尽管埃及人的戊型肝炎病毒血清阳性率最高,但埃及医院并未常规诊断戊型肝炎病毒感染。埃及人感染戊型肝炎病毒的最初表现为亚临床感染,不过也有进展为暴发性肝衰竭的记录。随着血清学和分子检测方法的改进以及对戊型肝炎病毒研究的增加,越来越清楚的是,戊型肝炎病毒对埃及人构成威胁,应考虑采取预防措施以降低感染率和可能出现的并发症。
