Hepatitis E virus (HEV) infection is an important cause of acute viral hepatitis in tropical and sub-tropical regions that occurs both as epidemic episodes and sporadic cases. The aim of this investigation was to estimate the prevalence of total immunoglobulin (Ig) anti-hepatitis E virus (anti-HEV) and the risk factors associated to two communities in Havana City. Serum samples (n=469) obtained from healthy individuals with no history of viral hepatitis were screened for total anti-HEV by enzyme immunoassay (EIA). An overall prevalence of 10% (47/469) (95% CI; 7.52-13.19%) was obtained. Higher anti-HEV prevalence was found in the municipality of Marianao (12.1%) compared to Playa (7.1%). Analysis of risk factors revealed a significant association of total anti-HEV prevalence in age group 41-60 years old, with a risk ratio of 3.21 (95% CI: 1.09-9.7) (P=0.01). No relation was found between anti-HEV and other variables such as gender, risk occupations, surgery and transfusions. The detection of total anti-HEV in individuals with no overt acute hepatitis suggests the existence of sub-clinical or anicteric HEV infection in these municipalities.

Hepatitis E virus (HEV) is recognized as an emerging zoonosis. Pigs and wild boars are considered the main reservoirs of zoonotic HEV-3 and HEV-4 genotypes. In Europe, autochthonous human cases of hepatitis E, mainly associated with HEV-3 and consumption of raw or undercooked pig and wild boar liver/meat, have increased over the last decades.

Objectives: Following the outbreak of hepatitis E in camps for internally displaced persons (IDPs) in Borno State in 2017, we assessed hepatitis B, C, and E biomarkers (hepatitis B surface antigen [HBsAg], anti-HBC, anti-hepatitis E virus [HEV] immunoglobulin [Ig] G, and anti-HEV IgM) among IDPs in three camps in Borno State, Nigeria, to determine seroprevalence rates in these understudied populations.

Methods: A total of 454 IDPs, including pregnant women and breastfeeding mothers, were randomly selected, and their demographic, clinical, and epidemiological data were collected. Blood samples were tested for HBsAg and anti-hepatitis C virus (HCV) using rapid tests, anti-HEV IgM, and anti-HEV IgG using enzyme-linked immunosorbent assay.

Article Synopsis
  • - A study was conducted in Piauí State, Brazil, to assess the prevalence of Hepatitis E Virus (HEV) among blood donors, involving 890 participants with a median age of 33.4 years, mostly males from the Mid-Northern region.
  • - Blood samples were tested for anti-HEV IgG and IgM antibodies using advanced techniques, alongside PCR testing for HEV RNA.
  • - The findings showed low prevalence rates for anti-HEV IgG (1.35%) and IgM (0.11%), with no HEV-RNA detected, indicating minimal HEV infection among blood donors in the area.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by a multifactorial etiology in which genetic and environmental factors interplay. An exclusively cutaneous condition has been described and defined as cutaneous lupus erythematosus (CLE). In Italy, a nationwide blood donor survey found an overall HEV prevalence of 8.

Hepatitis E virus (HEV) is considered as an emerging zoonotic pathogen circulating in a wide range of animals. In recent decades, the genus Paslahepevirus frequently isolated in pigs were the most involved in human clinical practice. In addition, the genus Rocahepevirus have been isolated in rodents, and transmission to humans is increasingly reported worldwide, although gaps remain regarding the exposure factors.
