[Echinococcosis/hydatidosis in Emilia-Romagna: a study of hospital admissions in the period of 1989-1993].

An overview of the epidemiology human echinococcosis/hydatidosis is presented for the Emilia-Romagna region during the period 1989-1993. Data were extracted from hospital discharge reports. The description was based on 806 discharges totaling 10187 days of stay. Thirty-five percent of the patients discharged were residents outside the Emilia-Romagna region. A significant statistical correlation was identified between a high average yearly incidence of the disease and a relatively small jurisdiction of residency. No correlation was established between average yearly incidence and number and density of sheep and goats and farms and estimated dogs.
