Between 1996 and 2003, 186 cases of hepatitis E were serologically diagnosed. Of these, 17 (9%) were not associated with recent travel abroad. Patients were >55 years old (range, 56-82 years old) and tended to be male (76%). Two patients presented with fulminant hepatitis. A total of 129 (69%) cases were associated with recent travel to countries where hepatitis E virus (HEV) is hyperendemic. Compared with patients with travel-associated disease, patients with non-travel-associated disease were more likely to be older, living in coastal or estuarine areas, not of South Asian ethnicity, and infected by genotype 3 strains of HEV. The genotype 3 subgenomic nucleotide sequences were unique and closely related to those from British pigs. Patients infected by HEV indigenous to England and Wales tended to belong to a distinct demographic group, there were multiple sources of infection, and pigs might have been a viral reservoir.
1996年至2003年间,血清学诊断出186例戊型肝炎病例。其中,17例(9%)与近期出国旅行无关。患者年龄大于55岁(范围为56至82岁),且男性居多(76%)。两名患者出现暴发性肝炎。共有129例(69%)病例与近期前往戊型肝炎病毒(HEV)高度流行国家的旅行有关。与旅行相关疾病患者相比,非旅行相关疾病患者更可能年龄较大、居住在沿海或河口地区、非南亚族裔,且感染的是HEV 3型毒株。3型亚基因组核苷酸序列独特,且与英国猪的序列密切相关。英格兰和威尔士本土感染HEV的患者往往属于一个独特的人群,存在多种感染源,猪可能是病毒储存宿主。
