Background Hepatitis E virus (HEV) is a significant pathogen of viral hepatitis and can be transmitted through fecal-oral route. Epidemiological data concerning HEV in goats, however, are relatively sparse to date. Here, the prevalence and characteristics of HEV isolated from goats at slaughterhouse were investigated in Tai'an region, China. Methods Anti-HEV immunoglobulin G (IgG) in blood sa...
Hepatitis E virus (HEV) is responsible for epidemics and endemics of acute hepatitis in humans, mainly through waterborne, foodborne, and zoonotic transmission routes. HEV is a single-stranded, positive-sense RNA virus classified in the family Hepeviridae and encompasses four known Genotypes (1-4), at least two new putative genotypes of mammalian HEV, and one floating genus of avian HEV. Genoty...
Hepatitis E virus (HEV) is an emerging pathogen associated with acute viral hepatitis, and HEV is becoming increasingly recognized. Approximately 2% of acute viral hepatitis is caused by HEV, and 18 cases of hepatitis E have been reported in Korea. Of these cases, only two have involved a history of travel from India, which suggests that they were imported cases. The remaining reported cases in...
BACKGROUND China is an endemic area for hepatitis E virus (HEV). The previous surveys of anti-HEV seroprevalence are cross-sectional. This study aimed to investigate the prevalence of infection among pregnant women and their children in Jiangsu, China, and to observe postpartum anti-HEV evolution. METHODS Sera from 497 women collected during pregnancy and 6-year postpartum and from their 497 ...
چکید ه سابقه و هدف ویروس هپاتیت (HEV) E به‌عنوان شایع‌ترین عامل هپاتیت حاد ویروسی بین بالغین جوان، در کشورهای در حال توسعه شناخته شده است. مطالعه حاضر با هدف تعیین فراوانی آنتی‌بادی ضد HEV در اهداکنندگان خون شهر تبریز، در سال 1383 انجام شد. مواد و روش‌‌ها بررسی فوق به صورت مقطعی (Cross-Sectional) و در ماه‌های مرداد و شهریور 1383 در میان اهداکنندگان خون در شهر تبریز اجرا شد. 399 مرد با...
Hepatitis E virus (HEV) is the major cause of enterically transmitted non-A, non-B hepatitis in many developing countries and is also endemic in many industrialized countries. Due to the lack of an effective cell culture system and a practical animal model, the mechanisms of HEV pathogenesis and replication are poorly understood. Our recent identification of swine HEV from pigs affords us an op...
Zoonotic potential of a rat-derived hepatitis E virus (HEV), designated as HEV-C1, remains unknown. To evaluate the risk for HEV-C1 infection in humans, paired sera of 208 hospitalized febrile patients collected from 2001 to 2003 in Hanoi, Vietnam, were examined for IgG antibodies to HEV-C1 and genotype 1 HEV (HEV-1), which is common in humans. IgG antibodies to virus-like particles (VLPs) of H...
Hepatitis E virus (HEV) is a major cause of acute hepatitis in many developing countries. This study describes an outbreak of HEV infection in Al-Sadr city, Baghdad. Blood samples obtained from patients with jaundice attending 19 primary health care centres in AI-Sadr city during a 6-month period in 2005 were tested for HEV. HEV (IgM) antibodies were detected in 38.1% of 268 patients. The assoc...
BACKGROUND Human hepatitis E virus (HEV) infections are considered an emerging disease in industrialized countries. In the Netherlands, Hepatitis E virus (HEV) infections have been associated with travel to high-endemic countries. Non-travel related HEV of genotype 3 has been diagnosed occasionally since 2000. A high homology of HEV from humans and pigs suggests zoonotic transmission but direct...
Hepatitis E virus (HEV) is a member of the genus Orthohepevirus in the family Hepeviridae and the causative agent of hepatitis E in humans. HEV is a major health problem in developing countries, causing mortality rates up to 25% in pregnant women. However, these cases are mainly reported for HEV genotype (gt)1, while gt3 infections are usually associated with subclinical courses of disease. The...
