In 2004, a major outbreak of hepatitis A among tourists returning from Egypt involved 351 case-patients from 9 European countries who were infected with a single strain (genotype 1 b). The case-control study identified orange juice as the most likely infection vehicle. Vaccination against hepatitis A virus is strongly recommended before travel to disease-endemic areas.

OBJECTIVE The aim of this study was to determine the prevalence rate of hepatitis A virus (HAV) and the socio-epidemiological factors affecting HAV among children aged 0-18 years in Eastern Turkey. MATERIALS AND METHODS The study sample consisted of 226 children aged 0-18 years who were registered at the Pediatrics Department of Atatürk University Medical Faculty for any reason except jaundic...

The main goal of this study was to test the feasibility of using urine for diagnosing hepatitis A virus (HAV) infections. A correlation of 90.78% between the test results of urine and serum samples was obtained. Four outbreaks of hepatitis A were confirmed by testing only urine samples. The levels of anti-HAV immunoglobulin M (IgM) antibodies in urine samples remained stable during 6 months of ...

Helicobacter pylori and hepatitis A virus (HAV) are thought to have similar routes of transmission and epidemiology. This study investigated the seroprevalence of these 2 pathogens among children in rural, central Taiwan. Serum samples were collected from 856 children between 2010 and 2012 and levels of anti-HAV and anti-H. pylori antibodies were measured by ELISA. Questionnaires were used to i...

    Abstract   Background: Hepatitis B virus infection is an important cause of liver morbidity and   mortality worldwide. HDV changes the natural course of HBV. The prevalence of HDV infection wasn’t determined in the various groups of HBV infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and HCC) in Iran. We aimed to research the prevalence of hepatitis D virus infection in v...

Serum samples from 465 subjects aged between 1 and 25 years were tested for antibody against hepatitis A virus (HAV) [anti-HAV IgG and IgM] to determine the seroprevalence of HAV antibody and do a cost-benefit analysis for decision making about vaccination against HAV among the general population of Bangladesh. A high prevalence of anti-HAV (74.8%) was observed in the study population; the whol...

During 2009 there was an increased incidence of acute hepatitis A virus (HAV) infection among homosexual males which, in our institute, outnumbered the number of cases in travellers, thus becoming the prime HAV risk factor. Some of our HAV cases occurred in HIV-infected subjects. This observation underlines the action of HAV as a sexually transmitted infection and urges preventive measures, suc...
