title: [Incidence and duration of blood HBs antigen in convalescents after type B viral hepatitis].
abstract: The presence of HBs Ag was determined by contraelectrophoresis in 500 convalescents after hepatitis B, at the moment of discharge and after 1--3 and 6 months. Antigen carriage is prolonged in hepatitis B, 51% of the convalescents being positive on discharge and 10% remaining persistent carriers. This was more frequent in males, young adults and those who had suffered from mild, prolonged forms of the disease. As only 42% of the patients became negative within the first 20 days of hospitalization it became necessary to prolong their stay in hospital and to follow up the patients subsequently in an out-patient unit.
