  METHODS
  We studied retrospectively the files of 2014 patients, hospitalized with the diagnosis of acute viral hepatitis in the Bacău County Hospital, from 1996 to 2005.
  
  
  RESULTS
  We saw that the only type the incidence of which lowered in time was the B-type hepatitis. The A acute hepatitis witnessed two epidemic peaks. The clinical cases of the male young patients prevailed. In 91.6% of cases, the infection source could not be established. The average incubation period was 21 days for viral hepatitis A, 65 for B and 80 for C. Hospitalized anicteric forms represented 2.8% of total. Extended forms were recorded with 3.6% patients (50.9% of them with B virus) and severe forms with 10.3% (among these, 66.7% with B virus). A fulminate evolution was noticed with 0.65% of cases. The global mortality was 0.4% and 0.95% for B type.
