[The risks of transmitting viral hepatitis in a section of the city of Bucharest].

The authors of the present paper consider that 82.3% of all cases of viral hepatitis in a Bucharest district were transmitted nonparenterally and only 17.7% were transmitted parenterally. They used the information on the way and mode of transmission, recorded in the epidemiologic investigations, of the cases of viral hepatitis without HBsAg in 1987 and of those with HBsAg in 1983-1987, respectively. The highest values of the risk of catching the disease were calculated for the infective social contact in family, in the viral hepatitis with HBsAg (60.9%), and for the infective social contact in collectivities (46.4%) in the viral hepatitis without HBsAg. These data have to be checked up by prospective epidemiologic studies, randomized and controlled.
