  1. Incidence of and risk factors for hepatitis A in Italy : public health indications from a 10-year surveillance.

    Article - En anglais


    This study aimed to evaluate the incidence of and risk factors for acute viral hepatitis A (HAV) in Italy.


    Data were from a surveillance system for type-specific acute viral hepatitis (SEIEVA).

    To estimate the association of hepatitis A cases with the potential risk factors (Odds Ratios) and the proportion of all hepatitis A cases attributable to a given risk factor (population attributable risk), hepatitis B cases were used as controls.

    Independent predictors of HAV were estimated by conditional multiple logistic regression.


    During the period 1985-1994,25553 viral hepatitis cases were reported.

    Of these, 6408 (25%) were due to hepatitis A (HAV).

    HAV incidence declined from 10/100000 in 1985 to 2/100000 in 1987.

    Since 1991, however, an increase in HAV has been observed.

    The majority of cases were 15-24 years old ; the incidence was higher in males and in subjects residing in southern Italy.

    Only one death (0.02%) was observed.

    Shellfish consumption was the most frequently reported risk factor (62%). The proportion of cases reporting personal contact with an icteric case, travel to a high-medium endemic areas, and family contact with a child attending a day-care centre (household of day-care child) was 17%, 19% and 15%, respectively.

    The results of multivariate analysis showed that shellfish consumption (OR=2.6 ; 95% CI=2.4-2.9), travel to endemic areas for people residing in northern and central Italy (OR=5.4 ; 95% CI=4.6-6. (...)
