Hepatitis A virus (HAV) and hepatitis E virus (HEV) infections occur chiefly as a result of unhygienic conditions. The purpose of this study was to assess the seroprevalence of antibodies to both viruses in central Burkina Faso in the absence of a recorded hepatitis epidemic. Serum samples from 178 blood donors (131 males and 47 females) and from 189 pregnant women were collected from November ...

Worldwide the prevalence of Hepatitis A virus in various countries are grouped into high, intermediate low and very low endemicity. Even in USA having very low endemicity have incidence of acute hepatitis A of 12.0 cases/100,000 persons in 1995.To prevent mortality and morbidity related with Hepatitis A virus infection, after implementation of routine childhood Hepatitis A vaccination in USA th...

Hepaxpert-I is an expert system that interprets the results of routine serologic tests for infection with hepatitis A or B virus. The tests measure antibody to the hepatitis A virus (anti-HAV), IgM antibody to the hepatitis A virus (IgM anti-HAV), hepatitis A virus (HAV) in the stool, hepatitis B surface antigen (HBsAg) and antibody (anti-HBs), antibody to hepatitis B core antigen (anti-HBc and...

BACKGROUND/AIMS Few studies have investigated hepatitis A virus (HAV) seroepidemiology in Koreans with chronic liver disease (CLD). This study compared the prevalence of IgG anti-HAV between the general healthy population and patients with hepatitis B virus-related CLD (HBV-CLD), with the aim of identifying predictors of HAV prior exposure. METHODS In total, 1,319 patients were recruited betw...

BACKGROUND In Canada, inactivated hepatitis A vaccines are targeted selectively at those at increased risk for infection or its complications. In order to evaluate the need for routine hepatitis A vaccination programs in Vancouver for street youth, injection drug users (IDUs) and men who have sex with men (MSM), we determined the prevalence of antibodies against hepatitis A virus (HAV) and risk...

Introduction It is now recognized that the hepatitis A virus (HAV), and hepatitis B virus (HBV) are antigenically and morphologically distinct (Dane, Cameron and Briggs, 1970; Feinstone, Kapikian and Purcell, 1973) and there are reports of patients who have had repeated attacks of hepatitis owing to exposure to the different viruses (Mosley et al., 1977). It is not surprising, therefore, that c...

conclusions available limited studies show that iranian healthcare personnel need hav vaccination. however, for selecting an appropriate preventive method for this high risk group, more original studies are still needed. results a gradual shift in age of hav infection has been seen from childhood toward adulthood. data about hav seropositivity among iranian hcws are very limited. however based ...

Encephalitis is caused by multiple organisms, but rarely by the hepatitis A virus. A 27-year-old man visited our hospital because of fever, altered consciousness, and seizures. On physical exam, a stuporous mentality and neck stiffness were found. On laboratory exam, elevated liver enzymes and cerebrospinal fluid abnormalities, including pleocytosis and elevated protein levels were observed. Th...

Two human hypatitis viruses have been identified and characterized, but one or more additional agents exist. Hepatitis B virus (HBV) is a complex 42-nm predominantly double-stranded DNA virus with distinct surface and core antigens and an endogenous DNA polymerase. Hepatitis A virus (HAV) is a 27-nm RNA virus with enterovirus-like properties. Progressively more sensitive and specific immunologi...
