title: Antibody to hepatitis A virus after overt and asymptomatic hepatitis A infection.
abstract: The titres of antibody to hepatitis A virus (anti-HAV) were found to fall rapidly during 3-4 years after hepatitis A and more slowly thereafter, though they never reached undetectable levels in at least 23 years. The levels of anti-HAV in convalescents after overt hepatitis A were found to be significantly much higher than in those who had anti-HAV as a result of asymptomatic infection.
