EPIDEMIOLOGIC-STUDY OF HOUSEHOLDS OF PATI ENTS WITH HYDATIDOSIS - A HIGH-RISK POPULATION

A serological study was undertaken by means of indirect hemagglutinati on (IHA) in 57 households of eleven patients with confirmed pulmonary hydatidosis (by serology and surgical procedure). Serum samples from 4 0 blood donors were used as control group. The IHA positivity rates we re 90.8%, 40.3% (23/57) and 2.5% (1/40) in patients with hydatidosis, households of these patients and blood donors (control group). Hydatid osis was confirmed in 4 out of 23 cases of IHA positive households. Th e high incidence by IHA in households living with patients with hidati dic disease can be a good screening parameter to identify a high risk asymptomatic population carrying the disease at an early phase.
