[Experience with the parallel use of immunoenzyme analysis and copro-ovoscopy for assessing the clonorchiasis infectivity of the population of Khabarovsk Territory].

The paper describes how enzyme immunoassay (EIA) and copro-ovoscopy are concurrently used to define the spread of clonorchiasis among the population of the Nanaĭsk District in the Khabarovsk Territory. It shows the efficiency of EIA in seroepidemiological surveys and the possibility of its use in endemic areas. The sensitivity of EIA to determine antibodies to Clonorchis antigens was 70.58% and its specificity was 98.4%. The assay is recommended for wide application in clinical and epidemiological practice in the foci of the disease. The total affliction of the population, which was calculated by 2 techniques is 33.7% +/- 3.0.
