Hepatitis E virus (HEV) is a zoonotic virus that can cause acute hepatitis in humans. Besides the fecal-oral route, transmission can occur by consumption of undercooked pig liver. Genotype 3 is the most frequent genotype found in Europe. Studies on HEV in slaughter-age pigs have not been conducted in Serbia so far. Pork meat production and consumption in Serbia is on average, higher than in the rest of Europe. With the aim to identify the circulating HEV genotypes, pig livers and swab samples from three pig slaughterhouses located in three different sub-regions of Serbia were collected. A nested RT-PCR was used to amplify the hypervariable HEV ORF-1 region (334 bp). The amplicons yielded in this study were sequenced, and a molecular phylogeny analysis based on the maximum likelihood method, including HEV sequences reported in several other countries, was performed. The average prevalence of HEV genotype 3 in 3-month-old pigs was 34%. Phylogenetic analysis revealed the majority of HEV amplification fragments from Serbia were grouped in four clades within sub-genotype 3a and were also genetically related to German, Italian, Slovenian, and American HEV sequences. Sub-genotypes 3b and 3j were also found in a single pig each. This study provides the first analysis of the genetic diversity and circulation dynamics of HEV in pigs at slaughterhouses in Serbia.

The occurrence of hepatitis E virus (HEV) in patients with Schistosomiasis mansoni (SM) is still poorly understood in Brazil. The objective of this study was to estimate the seroprevalence of anti-HEV IgG in patients with SM and its association with the periportal fibrosis (PPF), assessed by serum markers and ultrasound criteria. This cross-sectional study was carried out in an endemic area in Pernambuco, Brazil, with schistosomal patients who underwent coproscopic survey.

Infection with one or several of the five known hepatitis viruses is a leading cause of liver disease and poses a high risk of developing hepatocellular carcinoma upon chronic infection. Chronicity is primarily caused by hepatitis B virus (HBV) and hepatitis C virus (HCV) and poses a significant health burden worldwide. Co-infection of chronic HBV infected patients with hepatitis D virus (HDV) is less common but is marked as the most severe form of chronic viral hepatitis.

Background: Hepatitis E virus (HEV) causes acute jaundice and poses an important public health problem in low- and middle-income countries. Limited surveillance capacity and suboptimal access to diagnostics leads to under-reporting of HEV infections in affected countries, including Nepal. Serum antibodies against HEV are indicative of past infection.

SUMMARYHenipaviruses were first identified 30 years ago and have since been associated with over 30 outbreaks of disease in humans. Highly pathogenic henipaviruses include Hendra virus (HeV) and Nipah virus (NiV), classified as biosafety level 4 pathogens. In addition, NiV has been listed as a priority pathogen by the World Health Organization (WHO), the Coalition for Epidemic Preparedness Innovations (CEPI), and the UK Vaccines Research and Development Network (UKVN).

Background: Recently, there has been increasing interest in the exploration of the association between the hepatitis E virus () infection and malignancies; however, epidemiological data for infection among women with a gynecological tumors (GT) are limited. Herein, we investigated the correlation between and GT in Chinese women.
Methods: We recruited 452 women diagnosed with a primary GT and 452 healthy volunteers to investigate the possible routes and risk factors for infection.
