RATIONALE Hepatitis A viral infection is a well-known cause of subclinical or acute self-limited hepatitis. Few cases of hepatitis A virus (HAV)-associated acute liver failure (ALF) have been reported in low HAV endemic countries annually. PATIENTS CONCERNS To investigate the possible factors that affected the severity of HAV infection, a family cluster infected with the HAV subgenotype IB st...

This study examined the prevalence of hepatitis A (HAV), B (HBV), C (HCV), and Human Immunodeficiency Virus (HIV) co-infection among Injection Drug Users (IDUs) in Los Angeles County, California, and predictors of multiple infections in this population. Six hundred seventy-nine IDUs were recruited from October 2002 through June 2004. Participants completed questionnaires to elicit demographic, ...

Hepatitis A virus (HAV) and hepatitis E virus (HEV) are both transmitted by faecal-oral route. More local data on hepatitis A relative to hepatitis E was available over the last decades. Hong Kong is of intermediate endemicity for HAV []. Since 1988 with the breakdown of reported hepatitis according to aetiologic agents, the largest epidemic of hepatitis A occurred in 1992, with over 3,500 case...

This cross-sectional study was carried out between August 2011 and July 2012 in the city of Campos dos Goytacazes in Rio de Janeiro State, Brazil. Dried blood spot samples were collected on filter paper from 919 individuals between the ages of 1 and 19 and were tested for antibodies against the hepatitis A virus (anti-HAV). The total prevalence was 20.7%, while 94.7% of children under the age o...

Artery Disease To the Editor: We read with great interest the paper by Marek Smieja and colleagues1 showing that exposure to hepatitis A virus (HAV) was not associated with an excess risk of subsequent myocardial infarction, stroke, or cardiovascular death in Heart Outcomes Prevention Evaluation (HOPE) study patients. Total pathogen score based on seropositivity of 4 pathogens (Chlamydia pneumo...

Hepatitis A virus (HAV) is a causative agent of acute viral hepatitis for which an effective vaccine has been developed. Here we describe ultra-deep pyrosequences (UDPSs) of HAV 5'-untranslated region (5'UTR) among cases of the same outbreak, which arose from a single source, associated with a revolving sushi bar. We determined the reference sequence from HAV-derived clone from an attendant by ...

Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic liver disease (CLD), but this has been deemed unnecessary in Korea since the immunity against HAV was almost universal in adults. However, this practice has never been reevaluated with respect to the changing incidence of adult acute hepatitis A. We retrospectively reviewed the medical records of 278 patients w...

The aim this study determine cycle human infection by HAV contaminating water flowing into environment. We ...

HEPAXPERT is a knowledge-based system that interprets the results of routine serologic tests for infection with hepatitis A and B viruses. The following tests are included: hepatitis A virus anti-bodies (anti-HAV), IgM antibodies to the hepatitis A virus (IgM anti-HAV), hepatitis A virus (HAV in stool, hepatitis B surface antigen (HBsAg) and antibodies (qualitative anti-HBs, quantitative anti-H...
