Hepatitis E virus (HEV) causes acute or chronic hepatitis in humans and can be transmitted via the fecal-oral route. Pigs are one of the main reservoirs for this infection. Sixty pigs, 4-5 months of age, on a swine herd in Japan had detectable anti-HEV IgG antibodies, and five (8.3%) of them had ongoing infection of genotype 3 HEV. Five HEV strains obtained from the viremic pigs shared 98.8-100% nucleotide identity, and one representative strain (swHE1606845), whose entire genomic sequence was determined in this study, differed by 14...

Fecal contamination of drinking water is associated with large hepatitis E virus (HEV) outbreaks of genotypes 1 and 2 in endemic areas. Sporadic transmission of HEV genotypes 3 and 4 in high-income countries has been associated with exposure to blood and animal contact. The objective of the study was to identify the risk factors for hepatitis E and the genotype(s) causing sporadic hepatitis E in Dhaka, Bangladesh. We selected, from a diagnostic center in Dhaka between November 2008 and November 2009, cases presenting with jaundice and anti-HEV IgM antibodies and age-matched controls were defined as those with no history of jaundice and normal blood test results...

Estimates of the annual numbers of foodborne illnesses and associated hospitalizations and deaths are needed to set priorities for surveillance, prevention, and control strategies. The objective of this study was to determine such estimates for 2008-2013 in France. We considered 15 major foodborne pathogens (10 bacteria, 3 viruses, and 2 parasites) and estimated that each year, the pathogens accounted for 1.28-2.23 million illnesses, 16,500-20,800 hospitalizations, and 250 deaths. Campylobacter spp., nontyphoidal Salmonella spp...

Nucleotide-based methods are conventionally used to classify the hepatitis E virus (HEV) genotypes. A serological enzyme immunoassay (EIA) using open reading frame 3 (ORF3) C-terminal peptides was developed to conveniently and accurately classify and evaluate the genotypes of HEV. The sera of mice immunized with HEV genotype 1, 3 and 4 reacted highly specifically to the peptides of the corresponding genotypes. Most (84.2%) clinical sera infected with HEV genotype 4 were positive for anti-HEV antibodies when tested with the ORF3 peptides of genotype 4, but were negative for genotypes 1 and 3...

Hepatitis E virus (HEV) causes an acute, self limiting hepatitis in normal individuals and leads to chronic disease in immunocompromised individuals. HEV infection in pregnant women results in a more severe outcome, with the mortality rate going upto 30%. Though the virus usually causes sporadic infection, epidemics have been reported in developing and resource starved countries. No specific anti-viral exists against HEV. A combination of interferon and ribavirin therapy has been used to control the disease with some success...

Antiviral treatment options for chronic Hepatitis E Virus (HEV) infections are limited and immunological determinants of viral persistence remain largely unexplored. We studied the antiviral potency of pegylated interferon-α (pegIFNα) against HEV infections in humanized mice and modelled intrahepatic interferon stimulated gene (ISG) responses. Human gene expression levels in humanized mouse livers were analyzed by qPCR and Nanostring. Human CXCL10 was measured in mouse serum. HEV genotype 3 (gt3) infections were cleared from liver and feces within 8 pegIFNα doses in all mice and relapsed after a single pegIFNα injection in only half of treated animals...

The incidence and prevalence of hepatitis E virus (HEV) infection has increased in many developed countries over the last decade, predominantly due to infection with genotype 3 (G3) HEV. Infection with HEV G3 is important in transplant recipients because it can persist in immunosuppressed individuals, leading if untreated to the development of chronic hepatitis and significant liver fibrosis. The British Transplantation Society (BTS) has developed Guidelines for "Hepatitis E & Solid Organ Transplantation" to inform clinical teams and patients about hepatitis E, to help increase the recognition of persistent hepatitis E infection, and to provide clear guidance on its management...

Data from recent studies suggest rising incidence rate of hepatitis E virus (HEV) infection in the UK. HEV infection may take a severe and persistent course in immunocompromised patients, including transplant recipients on immunosuppressives, patients with HIV, haematological malignancies and in idiopathic CD4(+) T lymphocytopenia. The prevalence of HEV in primary antibody deficiency (PAD) disorders is still unknown. The aim of this study was to investigate HEV infection in 27 patients with PAD with unexplained, persistently elevated liver enzymes...

Hepatitis E virus (HEV), rotavirus (RV), and porcine enteric calicivirus (PEC) infections are common in swine and raises concerns about the potential for zoonotic transmission through undercooked meat products. Enteric viruses can potentially contaminate carcasses during meat processing operations. There is a lack of information on the prevalence and control of enteric viruses in the pork processing chain. This study compared the incidence and levels of contamination of hog carcasses with HEV, RV and PEC at different stages of the dressing process...

In January 2012, Mongolia started a hepatitis A vaccination program, which has not yet been evaluated. The first occurrence of autochthonous acute hepatitis E in 2013, caused by genotype 4 hepatitis E virus (HEV), suggests the need for a routine study to monitor its prevalence. One hundred fifty-four consecutive patients who were clinically diagnosed with acute hepatitis between 2014 and 2015 in Ulaanbaatar, Mongolia were studied. By serological and molecular testing followed by sequencing and phylogenetic analysis, only one patient (0...

Hepatitis E virus (HEV) is known as zoonotic agent. The main reservoirs of HEV in Europe are pigs, wild boars, and deer. Hunting activity is considered to be a risk factor for HEV infection. We conducted a cross-sectional study among 1021 Polish hunters. To understand socio-demographic characteristics of this population and to gather information on potential exposures, all participants completed a questionnaire. Commercial immunoassays were employed to estimate seroprevalence anti-HEV. Samples with confirmed positive result of anti-HEV IgM were examined for HEV RNA...

Hepatitis E virus (HEV) is an increasingly important zoonotic infection in humans with HEV genotypes 3 and 4 being recognized as zoonotic pathogens. The relatively recently isolated genotype 3 rabbit HEV (rHEV-3) and the more well known genotype 3 isolates from humans and swine (hsHEV-3) have all been confirmed experimentally to be capable of infecting both non-human primates and specific-pathogen free (SPF) pigs. In a previous study rHEV-3 was shown to cause acute hepatitis in experimentally infected rabbits...

Since 2010, human hepatitis E infections have increased in England and Wales. Most cases are locally acquired and caused by hepatitis E virus genotype 3 (HEV G3). HEV G3 is linked to the consumption of pork products. The increase is associated with the emergence of a new phylotype, HEV G3-group 2 (G3-2, also known as G3abcdhij). Sixty individuals with confirmed hepatitis E infection and no history of travel outside the UK were recruited: 19 were infected with HEV G3-group 1 (G3-1 or G3efg) and 41 with G3-2...
