title: [Prevention of viral hepatitis].
abstract: Prevention of viral hepatitis infection involves health measures designed to avert transmission of viral agents and promote the use of gammaglobulin and vaccines. The availability of safe drinking water and improvements in quality of life result in better individual hygiene; these factors have had the greatest impact on hepatitis A prevention. Serum gammaglobulin administration has been replaced by vaccinations for pre-exposure, and to a great extent for post-exposure prophylaxis because of the progressively lower anti-HAV content of gammaglobulin and the short duration of the protective effect. Universal vaccination in childhood is the recommended measure for controlling hepatitis A. Adults belonging to high-risk groups should also undergo vaccination. The incidence of hepatitis B has decreased worldwide because of universal vaccination programs, initiated in preadolescence and childhood. Prevention of hepatitis C requires control of situations in which there is a likelihood of parenteral infection with the virus. Post-transfusion hepatitis has been virtually eradicated, but considerable effort is still needed to prevent nosocomial hepatitis.
