title: Enterically transmitted hepatitis. Hepatitis A and E viruses.
abstract: Enterically-transmitted hepatitis is caused by hepatitis A virus and hepatitis E virus. The most important agent is hepatitis A virus, which is distributed worldwide and infects all age groups. Most infections in children are minimally symptomatic and immunity is long-lasting, so severe disease tends to occur in nonimmune adults. Hepatitis E virus is found in the developing world and has a greater propensity for symptomatic infection of children. Both agents are transmitted via contaminated water, often through food vehicles.
