title: Type A viral hepatitis: epidemiology, diagnosis, and prevention.
abstract: Hepatitis A virus (HAV) infection occurs worldwide and is an important cause of acute viral hepatitis in the US. In this review, I cover the epidemiology, course of infection, clinical manifestations, serological responses, and prevention of this infection. Although most patients completely recover from this disease, elderly patients have a substantial mortality risk. Recently licensed vaccines are highly efficacious.
