HOSPITALIZATION RATE AND MEAN DAYS OF HOSPITALIZATION OF NOTIFIED VIRAL-HEPATITIS CASES IN ITALY

The hospitalization rate and the mean days of hospitalization of notif ied viral hepatitis cases in Italy were estimated by a specific survei llance system for acute viral hepatitis over the period 1987-1992. The hospitalization rate was very high, ranging from 88.8% for hepatitis A to 90.9% for non-A, non-B hepatitis, No changes were observed over t ime, For each type of hepatitis the highest figure was observed in the 15-24 year age group. The mean days of hospitalization of hepatitis B (24.2) and non-A, non-B (20.5) hepatitis was significantly higher (p < 0.05) than that of hepatitis A (16.5). The highest mean days of hosp italization of hepatitis A and B occurred in the 0-14 year age group, while for non-A, non-B hepatitis it was observed in subjects over 24 y ears of age. These findings indicate a nearly similar rate of hospital ization of all types of hepatitis. Hepatitis B and non-A, non-B hepati tis show a more prolonged course than hepatitis A.
