Hydatidosis was most frequently found in liver (67.5%) and lungs (23.7%) and more rarely in kidneys (0.4%), brain (0.2%), pancreas (0.2%), ovary (0.2%). Secondary hydatidosis was reported on 12.7% of cases and multiple cyst forms in 12.7% of cases. The distribution of cases by age group was relatively balanced, a slightly increased incidence being found in the 20-29 years age group (23.2%), about 1/3 of pulmonary localizations being reported in the age group. Post-surgery complications were reported in 13.5% of the total hepatic localizations and in 30% of the pulmonary localizations. The average number of days in hospital was 29.5 days/case. The average morbidity in the adult population in Banat over an eight years time interval was 5.36%ooo, being higher in Timiş county-7.8%ooo where a peak (11%ooo) was reported in 1987.
