HAV has a global distribution, and transmission primarily occurs by the fecal-oral route. The clinical manifestations of HAV infection can vary significantly and range from asymptomatic infection, usually seen in young children, to fulminant hepatitis, which can result in death. Genotype I is the most frequently reported. Genotypes I to III are subdivided into groups A and B.
HAV has six genotypes (I to VI) in which genotypes I to III are human isolates and IV to VI are only simian isolates. Hepatitis A virus (HAV) is a small, non-enveloped single-stranded RNA virus that belongs to the Picornaviridae family, genus Hepatovirus. Source: Wikipedia, Hepatitis A virus (Wikipedia) IgG antibody to HAV is also found in the blood following vaccination and tests for immunity to the virus are based on the detection of this antibody.Ĭopyright Text is available under the Creative Commons Attribution/Share-Alike License.
The presence of IgG antibody in the blood means that the acute stage of the illness is past and the person is immune to further infection. It is detectable from one to two weeks after the initial infection and persists for up to 14 weeks. IgM antibody is only present in the blood following an acute hepatitis A infection. The disease can be prevented by vaccination, and hepatitis A vaccine has been proven effective in controlling outbreaks worldwide.Īlthough HAV is excreted in the feces towards the end of the incubation period, specific diagnosis is made by the detection of HAV-specific IgM antibodies in the blood. Antibody produced in response to HAV infection persists for life and confers protection against reinfection. The risk for symptomatic infection is directly related to age, with >80% of adults having symptoms compatible with acute viral hepatitis and the majority of children having either asymptomatic or unrecognized infection. Overall occurrence acute liver failure from Hepatitis A is rare (approx. HAV infection produces a self-limited disease that usually does not result in chronic infection or chronic liver disease. In developing countries, and in regions with poor hygiene standards, the incidence of infection with this virus is high. It is transmitted by ingestion of contaminated food or water or through direct contact with an infectious person. Hepatitis A virus (Hep A or HAV) is an RNA virus that causes an acute infectious disease of the liver and is usually spread by the fecal-oral route.
