[A dynamic study of the immune response of the population in a focus of hydatid disease in Dzhambul Province, Kazakhstan].

Screening for hydatid disease in foci should be carried out making use of the two most effective immunologic methods, indirect hemagglutination (IHA) and enzyme immunoassay (EIA). In order to have more reliable data on the structure of infection focus and for an earlier detection of patients such studies should be carried out over time and be followed by clinical examinations of subjects in whom anti-Echinococcus antibodies are repeatedly detected in epidemiologically significant and higher titers in IHA and/or EIA. All seropositive subjects and patients operated on for hydatid disease should be followed up.
