The clinical manifestations of clonorchiasis were studied in 190 patients in the Amur River region. The severity of the disease correlated with the excretion rates of Clonorchis eggs. The peculiarity of the region is a rather low egg excretion; 66.8% of patients excreted as many as 100 eggs/g, 27.3%, up to 1000 eggs/g. Most examinees (94.3%) suffered from chronic gastroduodenitis and functional disorders of the biliary system.

The paper describes how enzyme immunoassay (EIA) and copro-ovoscopy are concurrently used to define the spread of clonorchiasis among the population of the Nanaisk 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.

Copro-ovoscopic survey of the human population in the Khabarovsk Territory and the analysis of data of account of territorial sanitary epidemiological station showed that people invaded with D. klebanovskii are registered only in areas whose rivers catadromous salmon come to spawn. Most of invaded people are recorded on the seashore. The risk of tapeworm invasion and the epidemiological characteristics of the carry-over zone are discussed.
