Hepatitis E virus (HEV) is the major cause of epidemic and sporadic hepatitis globally. Outbreaks are associated with fecal contamination of drinking water, yet the environmental reservoir of HEV between epidemics remains unclear. In contrast to neighboring countries, where epidemics and sporadic disease co-occur, HEV-endemic communities in rural Bangladesh seldom report outbreaks; sporadic hep...

BACKGROUND Hepatitis E virus (HEV) has been described as an emerging pathogen in Brazil and seems to be widely disseminated among swine herds. An autochthonous human case of acute hepatitis E was recently reported. To obtain a better understanding of the phenotypic profiles of both human and swine HEV strains, a experimental study was conducted using the animal model, Macaca fascicularis. MET...

Most cases of enterically transmitted non-A, non-B hepatitis in India have so far been attributed to hepatitis E virus (HEV) infection. Most of the documented studies of hepatitis have focused on the incidence of this disease in northern, western, and south central India. A small seroprevalence study was conducted in the eastern Indian city of Patna to assess the degree of HEV infection among a...

RA Hepatitis E, a disease caused by infection with the hepatitis E virus (HEV), is highly endemic in several developing countries in Asia and Africa where contamination of water supplies and lack of adequate sanitation are frequent. In these areas, a large proportion of cases of acute viral hepatitis are due to genotype 1 or 2 HEV infection. In contrast, the disease is quite infrequent in devel...

Recent studies have reported and provided nucleotide sequence data from divergent isolates of hepatitis E virus (HEV), including isolates from North America and Africa. Sera were investigated from 29 Chinese patients with a diagnosis of acute hepatitis and who were negative for hepatitis viruses A-E by serology (HEV was excluded by testing for IgG antibody only). To determine whether some patie...

BACKGROUND Hepatitis E virus (HEV) infections can lead to chronic hepatitis in immunocompromised patients. We have investigated the risk factors for HEV infection among solid-organ transplant recipients and the characteristics of these infections. METHODS We performed serological tests, quantified the virus, and genotyped the virus in plasma samples. We performed a case-control study with HEV...

Genotype 4 hepatitis E virus (HEV) is the dominant cause of hepatitis E in the People's Republic of China; swine are the principal reservoir. Our study was conducted in 8 rural communities of southern China, where families keep pigs near their homes. Phylogenetic analysis showed that 23 of 24 concurrent virus isolates from this region are genotype 4 strains. Among the study populations, immunog...

Hepatitis E virus (HEV) infection may cause acute hepatitis and lead to hepatic failure in developing and developed countries. We studied HEV seroprevalences in patients with hepatitis B virus (HBV) infection to understand the consequences of HEV superinfection in a Vietnamese population. This cross-sectional study was conducted from 2012 to 2013 and included 1318 Vietnamese patients with HBV-r...

Hepatitis E virus (HEV) infection can be responsible for chronic hepatitis in immunocompromised patients, and can rapidly evolve into fibrosis and/or hepatic cirrhosis. We present two cases of chronic hepatitis E, emphasizing the need to be aware of this entity as a growing etiology of hepatitis in transplant and immunocompromised patients.

An asymptomatic 35-year-old renal transplant recipient was noted to have deranged liver function tests. Liver biopsy revealed a portal inflammatory process with mild lobular activity and portal fibrous expansion, consistent with a virally mediated process. An extensive viral screen confirmed infection with Hepatitis E virus genotype 3 (HEV-3). There is increased awareness about locally acquired...
