To explore the genetic diversity of avian hepatitis E virus strains, we characterized the near-complete genome of a strain detected in 2010 in Hungary, uncovering moderate genome sequence similarity with reference strains. Public health implications related to consumption of eggs or meat contaminated by avian hepatitis E virus, or to poultry handling, require thorough investigation.

Avian hepevirus infections were detected in chickens suffering from big liver and spleen disease or hepatitis-splenomegaly syndrome in Australia, the USA and Europe. Available data indicate their genetic relationship to mammalian hepatitis E virus (HEV). In the present study, the near-complete genomic sequences of an Australian and a European isolate of avian hepatitis E virus (avian HEV) are reported for the first time. Furthermore, the phylogenetic relationship to other avian HEVs is determined. Sequence analyses of these isolates identified major genetic differences among avian HEVs. Most of them are located within the open reading frame (ORF)1 region, although only a few lie within conserved motifs of predicted domains. Non-silent mutations in the ORF2 region suggest the presence of potentially different epitopes among avian HEV isolates. Finally, phylogenetic analysis confirmed the distant relationship to mammalian HEV and additionally suggested that the avian HEVs can be separated into three

To determine the origin of hepatitis E virus in the Czech Republic, we analyzed patient clinical samples. Five isolates of genotypes 3e, 3f, and 3g were obtained. Their genetic relatedness with Czech strains from domestic pigs and wild boars and patient recollections suggest an autochthonous source likely linked to consumption of contaminated pork ...

Avian hepatitis E virus (HEV) is a single-stranded, positive-sense RNA virus with a complete genome of approximately 6.6 kb in size. To date, four major genotypes of avian HEV have been identified and classified into the Orthohepevirus B genus of the family Hepeviridae. The avian HEV associated with hepatitis-splenomegaly syndrome, big liver and spleen disease or hepatic rupture hemorrhage syndrome in chickens is genetically and antigenically related to mammalian HEV. With the increased genotypes of avian HEV identified, a broader host tropism is also notable in the epidemiological studies. Due to the lack of an efficient cell culture system, the mechanisms of avian HEV replication and pathogenesis are still poorly understood. The recent identification and characterization of animal strains of avian HEV has demonstrated the virus ability of cross-species infection. Although it has not yet been detected in humans, the potential threat of a zoonotic HEV capable of transmission to humans needs to be taken

Matthew Garrett PharmD Candidate 2015 It is estimated that around 20 million hepatitis E infections occur every year. The hepatitis E virus causes liver disease and is usually transmitted through contaminated drinking water. The highest prevalence of hepatitis E is seen in eastern Asia. Hepatitis E infection usually resolves in 4-6 weeks and is…

This is the case of a 56-year-old man who underwent heart transplantation. Within the first postoperative days, his respiratory and limb muscles weakened, which was attributed to critical illness polyneuromyopathy (CIPM). At day 70 post transplantation, he had increased liver enzyme levels and acute hepatitis E virus (HEV) infection was diagnosed. HEV RNA was found in the serum, stools, and cerebrospinal fluid. Results of further investigations suggested a possible HEV-related polyradiculoneuropathy. At transplantation, the patient was negative for immunoglobulin (Ig)G, IgM, and HEV RNA. A trace-back procedure identified the source of infection and concluded that HEV infection was contracted from blood transfusion 12 days prior to transplantation from an HEV RNA-positive donor. Tests of the organ donor for HEV were negative. Phylogenetic analysis revealed sequence homology between the HEV-3 strain of the patient and the HEV-3 strain of the blood donor. Despite ribavirin treatment, the patient ...

The aim of the study was to describe the characteristics of acute hepatitis E in Greater Cairo.

A significant proportion of patients with neuralgic amyotrophy also report a preceding infection, but no single infective agent predominates. A study of two cohorts of patients from the UK and the Netherlands found that 10% of patients had acute HEV infection.23 The UK cases were retrospectively identified, but those in the Dutch group were from a prospective trial of corticosteroid therapy. All were anicteric, had mildly elevated liver function tests (in some cases they were normal), and in all but one case, HEV RNA (genotype 3) was found in the serum. All were locally acquired infections, without a clear source of infection. There have now been over 30 cases of HEV-associated neuralgic amyotrophy reported in the literature, mostly from Europe.24 The clinical phenotype of HEV-associated neuralgic amyotrophy appears to be a bilateral disorder in middle-aged men, affecting any part of the brachial plexus in a patchy manner. Some patients have lumbosacral and phrenic nerve involvement. The outcome ...

Fulminant hepatic failure resulting from hepatitis E and coexistent Wilsons disease was diagnosed in a six year old girl six weeks after returning from a holiday in India. Wilsons disease was diagnosed on the basis of histological evidence of hepatocellular copper deposition, confirmed by biochemical estimation of liver copper concentration. Although severely damaged, the liver was non-cirrhotic. Hepatitis E virus (HEV) was diagnosed by nested polymerase chain reaction, the specificity of which was confirmed by direct sequencing of amplified DNA. Replication of HEV within the liver at the time of diagnosis was confirmed by selective amplification of the antigenomic strand of the virus obtained from total liver RNA. The patient had an orthotopic liver transplantation without recurrence of hepatitis and remains well at 19 months. Viral excretion, recorded by serial amplification of HEV RNA extracted from stool samples, persisted for 30 days after liver grafting. Severe vitiligo, present ...

Abstract. We describe a fulminant autochthonous hepatic failure caused by hepatitis E (HEV) in a patient admitted in our hospital for liver-transplant evaluation. The only risk factor recorded for this severe course was the use of oral contraceptives that are known to mimic a hormonal status similar to pregnancy. The diagnosis was based on the presence of IgG and IgM anti-HEV in the serum of the patient and confirmed by the isolation of a strain of HEV genotype 3f from a blood sample obtained the fourth day after hospital admission. HEV genotype 3 is present in human and swine populations in Spain. The patient began to recover while waiting for a liver transplant. To our knowledge, this is the first report of fulminant hepatitis E in a non-pregnant European patient on oral contraceptives.

Hepatitis E (genotype 1 and, to a lesser extent genotype 2) is endemic and can cause outbreaks in Southeast Asia, northern and central Africa, India, and Central America.[5][45] It is spread mainly by the fecal-oral route due to contamination of water supplies or food; direct person-to-person transmission is uncommon.[5][19] In contrast to genotypes 1 and 2, genotypes 3 and 4 cause sporadic cases thought to be contracted zoonotically, from direct contact with animals or indirectly from contaminated water or undercooked meat.[5][46] Outbreaks of epidemic hepatitis E most commonly occur after heavy rainfalls, especially monsoons because of their disruption of water supplies; heavy flooding can causes sewage to contaminate water supplies.[47][48]:78 The World Health Organization recommendation for chlorine on HEV inactivation, a free chlorine residual of 0.5 mg/L (6.7×10−5 oz/US gal) for 30 min (pH, ,8.0)[49] Major outbreaks have occurred in New Delhi, India (30,000 cases in 1955-1956),[50] ...

Hepatitis E (HEV) is a viral infection causing inflammation of the liver. It is primarily acquired by ingesting water contaminated with fecal matter. The virus is also transmitted from person to person through the fecal-oral route as a result of poor body hygiene practices. In some regions, such as Europe and Japan, pigs, deer, and wild boars are known to be reservoirs for Hepatitis E and it can be contracted by eating raw or undercooked meat such as pig liver and venison. ...

According to information from the Ministry of Health, the deceased included six pregnant women among other categories from the Havana and Goreangab informal settlements.. The outbreak has since spread from the capital to other administrative regions of the country. However, the cases are largely confined to five informal settlement in the Katutura local government area of Windhoek.. Speaking during an assessment tour of emergency responses in the affected settlements Friday, US ambassador to Namibia Lisa Johnson said Washington will help Namibia fight the Hepatitis E outbreak. We are seeing that there are still new cases in the areas of Windhoek every week and thats actually not to be unexpected, it does take months to get the hepatitis E outbreak under control. We will continue to assist, and I think by mid-July the National Health Emergency National Committee will have some sort of 6 months response review to see how we are doing altogether, and what needs to be done next, Johnson said. ...

Hepatitis E virus (HEV) is an under-recognised cause of acute hepatitis in high-income countries. The purpose of this study was to provide an overview of testing, diagnosis, surveillance activities, and data on confirmed cases in the European Union/European Economic Area (EU/EEA). A semi-structured survey was developed and sent to 31 EU/EEA countries in February 2016, 30 responded. Twenty of these countries reported that they have specific surveillance systems for HEV infection. Applied specific case definition for HEV infection varied widely across countries. The number of reported cases has increased from 514 cases per year in 2005 to 5,617 in 2015, with most infections being locally acquired. This increase could not be explained by additional countries implementing surveillance for HEV infections over time. Hospitalisations increased from less than 100 in 2005 to more than 1,100 in 2015 and 28 fatal cases were reported over the study period. EU/EEA countries are at different stages in their

We determined the hepatitis E virus (HEV) seroprevalence and detection rate in commercial swine herds in Italys utmost pig-rich area, and assessed HEV seropositivity risk in humans as a function of occupational exposure to pigs, diet, foreign travel, medical history and hunting activities. During 2011-2014, 2700 sera from 300 swine herds were tested for anti-HEV IgG. HEV RNA was searched in 959 faecal pools from HEV-seropositive herds and in liver/bile/muscle samples from 179 pigs from HEV-positive herds. A cohort study of HEV seropositivity in swine workers (n = 149) was also performed using two comparison groups of people unexposed to swine: omnivores (n = 121) and vegetarians/vegans (n = 115 ...

Hepeviridae is a family of viruses. Human, pig, wild boar, sheep, cow, camel, monkey, some rodents, bats and chickens serve as natural hosts. There are five species in this family, divided between two genera. Diseases associated with this family include: hepatitis; high mortality rate during pregnancy; and avian hepatitis E virus is the cause of hepatitis-splenomegaly (HS) syndrome among chickens.Orthohepevirus used to be known as Hepevirus. The virus that causes Hepatitis E belongs to the Orthohepevirus genus. Group: ssRNA+ Order: Unassigned Family: Hepeviridae Genus: Orthohepevirus Orthohepevirus A Orthohepevirus B Orthohepevirus C Orthohepevirus D Genus: Piscihepevirus Piscihepevirus A Viruses in the family Hepeviridae are non-enveloped, with icosahedral and spherical geometries, and T=1 symmetry. The diameter is around 32-34 nm. Genomes are linear and non-segmented, around 7.2kb in length. The genome has three open reading frames. This has been studied by examining the ORF1 and the capsid ...

We investigated the seroprevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) infection in subjects living in the community of Manguinhos, Rio de Janeiro, Brazil, and assisted at the Health Unit of Escola Nacional de Saúde Pública, Fundação Oswaldo Cruz. After formal consent, individuals were submitted to an interview using a standardized questionnaire. Anti-HAV and anti-HEV antibodies were detected by ELISA. Statistical analysis was carried out using the Epi-Info 6.04b software, to investigate possible associations between serological markers and risk factors. Results were regarded as significant when p value < 0.05. Although a high prevalence of anti-HAV was observed (87%), almost 50% of subjects under the age of 10 were susceptible to HAV infection, an unexpected rate in endemic areas. This fact could be attributed to improvements in environmental sanitation, occurring in this area in the last years. The increasing proportion of susceptible people may result in outbreaks of ...

Researchers at Rice University and their international colleagues have for the first time described the atomic structure of the protein shell that carries the genetic code of hepatitis E (HEV). Their findings, published in the Proceedings of the National Academy of Sciences, could mean that new ways to stop the virus may come in the not-too-distant future.

Viruses such as hepatitis A virus (HAV), noroviruses (NoV), sapoviruses, enteroviruses, astroviruses, adenoviruses, rotaviruses, and hepatitis E virus have all been implicated in food- and/or water-borne outbreaks of illness. This chapter deals with NoV and HAV detection in bivalve mollusks, soft fruits, and water. For bivalve mollusks, fecal indicators are measured either in the shellfish themselves or in their growing waters. When virus detection procedures are mentioned, the recurrent issue of detecting infectious or physical particles comes into discussion. Whenever possible, infectious assays coupled with identification methods are preferred for direct assessment of human health risk. Nucleic acid amplification techniques are currently the most widely used methods for detection of viruses in food and water and also enable investigators to gather information on the virus genotypes occurring in the environment and in food products, thus providing the most relevant epidemiological information,

Disability-adjusted life year (DALY) losses. The various hazards that can be present in water, excreta, wastewaters and polluted surface waters can have very different health outcomes. Some outcomes are mild (e.g., diarrhea,), while others can be severe (cholera, haemolytic uraemic syndrome associated with E. coli O157, or cancer); some are acute (diarrhea), while others are delayed (infectious hepatitis, cancer); some especially relate to certain age ranges and groups (skeletal fluorosis in older adults often arises from long-term exposure to high levels of fluoride in childhood; infection with hepatitis E virus has a very high mortality rate among pregnant women). In addition, any one hazard may cause multiple effects (e.g., gastroenteritis, Guillain-Barré syndrome, reactive arthritis and mortality associated with Campylobacter).. In order to support public health priority setting a common metric is required that can be applied to all types of hazard and takes into account different health ...

Hepatitis E represents a major health challenge worldwide and is still difficult to control. For example, prevention in disinfection is reaching its limits and vaccination is currently only available in China.

Cheng, Stark and colleagues prepared virus-like particles based on Hepatitis E proteins. The particles do not contain any virus DNA, so they cant multiply and spread and cause infections.. Such particles could be used as vaccines that are delivered through food or drink. The idea is that you would drink the vaccine, and after passing through the stomach the virus-like particles would get absorbed in the intestine and deliver vaccines to the body.. But the particles could also be used to attack cancer. Stark and Cheng did some tinkering with the proteins, so that they carry sticky cysteine amino acids on the outside. They could then chemically link other molecules to these cysteine groups.. They worked with a molecule called LXY-30, developed by researchers at the UC Davis Comprehensive Cancer Centre, which is known to stick to breast cancer cells.. The technique was tested in rodents as a way to target breast cancer.. By using a fluorescent marker, they could show that virus-like particles ...

A new hepatitis E virus (HEV-7) was recently found in dromedaries and 1 human from the United Arab Emirates. We screened 2,438 dromedary samples from Pakistan, the United Arab Emirates, and 4 African countries. HEV-7 is long established, diversified and geographically widespread. Dromedaries may constitute a neglected source of zoonotic HEV infections.

We evaluated the prevalence of hepatitis E virus (HEV) in the pork production chain in Czech Republic, Italy, and Spain during 2010. A total of 337 fecal, liver, and meat samples from animals at slaughterhouses were tested for HEV by real-time quantitative PCR. Overall, HEV was higher in Italy (53%) and Spain (39%) than in Czech Republic (7.5%). HEV was detected most frequently in feces in Italy (41%) and Spain (39%) and in liver (5%) and meat (2.5%) in Czech Republic. Of 313 sausages sampled at processing and point of sale, HEV was detected only in Spain (6%). HEV sequencing confirmed only g3 HEV strains. Indicator virus (porcine adenovirus) was ubiquitous in fecal samples and absent in liver samples and was detected in 1 slaughterhouse meat sample. At point of sale, we found porcine adenovirus in sausages (1%-2%). The possible dissemination of HEV and other fecal viruses through pork production demands containment measures ...

As one of the causative agents of viral hepatitis, hepatitis E virus (HEV) has gained public health attention globally. HEV epidemics occur in developing countries, associated with faecal contamination of water and poor sanitation. In industrialised nations, HEV infections are associated with travel to countries endemic for HEV, however, autochthonous infections, mainly through zoonotic transmission, are increasingly being reported. HEV can also be transmitted by blood transfusion. Nepal has experienced a number of HEV outbreaks, and recent earthquakes resulted in predictions raising the risk of an HEV outbreak to very high. This study aimed to measure HEV exposure in Nepalese blood donors after large earthquakes. Samples (n = 1,845) were collected from blood donors from Kathmandu, Chitwan, Bhaktapur and Kavre. Demographic details, including age and sex along with possible risk factors associated with HEV exposure were collected via a study-specific questionnaire. Samples were tested for HEV IgM, IgG

The seroprevalence and incidence of hepatitis A, B, C, and E virus infection were determined among North American missionaries (n = 328) serving in various geographic locations between 1967 and 1984. The mean age of subjects at entry into the study was 39.7 years (range 5-73 years); 65% were female: 89% had lived outside the United States before the study began. Seventy-eight percent of subjects served in sub-Saharan Africa during the study. At initial evaluation, 50.9% of the subjects had antibodies to hepatitis A virus (total anti-HAV), 8.5% to hepatitis B virus core antigen (total anti-HBc), 0.6% to hepatitis C virus (total anti-HCV by second- generation immunoblot assay), and 0% to hepatitis E virus (IgG anti-HEV). After an average period of service of 7.3 years (2,396 person-years total), 5.8% of the missionaries seroconverted to anti-HAV, 5.5% to anti-HBc, 0.6% to anti-HCV, and 0% to anti-HEV. This study indicates a relatively low risk of hepatitis C and E virus infection among ...

Initially, 22-year-old Emilia Indongo thought she was pregnant when she started feeling dizzy, weak, nauseous and started vomiting on Christmas Eve. It was only after 10 days of medical tests, including pregnancy tests, that she was told she is infected with hepatitis E. In the weeks of medical tests a weak Indongo shuttled between her home and hospital, while enduring episodes of vomiting and lying helpless in her bed.

A global expert on emerging and zoonotic animal viruses, Meng is a member of both the National Academy of Sciences and the National Academy of Inventors. His discovery of the swine hepatitis E virus (HEV) spurred a paradigm shift in recognizing HEV as a zoonotic virus that can cross species and infect humans.

Acute viral hepatitis can be caused by any of 5 hepatotropic viruses: hepatitis A and hepatitis E viruses are transmitted enterically and do not cause chronic hepatitis, hepatitis viruses B, C and D are transmitted parenterally and have the ability to cause chronic hepatitis. Other viruses that can cause hepatic inflammation include Epstein-Barr virus (EBV), herpes simplex virus (HSV), mumps, rubella, varicella-zoster virus, yellow fever virus, coxackie B virus, and adenovirus. Although these viruses can cause diagnostic confusion by producing liver inflammation and dysfunction, they are not primary causes of acute or chronic viral hepatitis. Clinical features of acute symptomatic viral hepatitis are common to all forms of viral hepatitis. There are no clinical features that unequivocally distinguish the individual types of hepatitis from each other; however, there are certain epidemiological patterns of transmission that may suggest a particular virus.. Hepatitis B virus (HBV) causes a wide ...

Tupaia (Tupaia belangeris chinensis, tree shrew) as a new experiment animal in medicine are non-rodent, small animals and close to primates in evolution. Experimental animals infected with viruses will affect the animals health, interference experiment, and even endanger the operators safety. Therefore, the viral infection in experimental animals has long been considered an important part of quality control. Lack of clearer viral natural infection information on the T. belangeris limits its use. Six viruses infection in 272 wild capture and artificial breeding Tupaia were investigated in this study. All serum samples were detected for the hepatitis B virus surface antigen, the total antibodies of HCV, hepatitis E virus (HEV), adenovirus (ADV), herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) by ELISA. The results showed that anti-HCV antibody and anti-HEV, ADV, HSV-1 IgG antibodies were negative, only one sample was positive of anti-HSV-2 IgG.. Three samples were ...

HEV is associated in humans with outbreaks and sporadic cases of acute hepatitis. The virus is considered endemic in tropical and subtropical countries of Asia, and Africa, as well as Mexico, but antibody prevalence studies suggest a global distribution for this virus. Large outbreaks that may involve thousands of cases of acute hepatitis occur in endemic regions. Sporadic cases are more common in industrialized countries. Human-to-human transmission seems rare in hepatitis E epidemics although infections can be transmitted by blood transfusion from acutely infected donors (Huzly et al., 2014, Hewitt et al., 2014). Members of Orthohepevirus A have been assigned to 7 different genotypes, HEV-1 to HEV-7. Recently a new HEV genotype (HEV-8) was proposed for viral variants isolated from Bactrian camels (Woo et al., 2016). Of these genotypes; HEV-1, HEV-2, HEV-3 and HEV-4 are most commonly associated with HEV infection in humans. Genotypes 1 and 2 are restricted to humans, whereas genotypes 3 and 4 ...

While mild in most cases, hepatitis E can lead to scarring of the liver, liver failure, neurological damage and even death.. A spokesperson for the UK Food Safety Authority said the risk of infection from properly cooked meat is low and encouraged consumers to ensure their pork products are thoroughly cooked until steaming hot throughout.. Another blow for Dutch food safety. Hepatitis E has been detected in 80% of liver sausage and pate products on sale in the Netherlands, Foodlog, a website dedicated to health and food, reports. Dutch virologists believe the use of unsterilised pigs blood in pork products may be to blame.. This is the second blow to the Netherlands food export industry since the beginning of August, when a public health scandal erupted because eggs contaminated with the banned insecticide fipronil were traced back to Dutch farms.. The fipronil scandal has since reached 17 European countries and the chemical has even been detected in food imports as far away as Hong ...
