Abstract
Human sparganosis in Korea was discussed on the bases of five human cases experienced by the present authors and 58 case records already reported by many previous authors, in aspects of epidemiology and clinical features. Sparganosis is not infrequent tissue helminthiasis now in Korea and the incidence has been evidently increased during past 10 years. It might be interpreted that improved medical delivery system and health care exposed the hidden but prevalent disease. The distribution of sparganosis in Korea is apparently subdivided into three major endemic areas; Kyunggi Do, Kyungsang Do and Hamkyung Nam Do. Although scanty in other areas of Korea, the distribution of this disease is presumably throughout the whole peninsula of Korea except Cheju Do. The majority of human cases of sparganosis in Korea has revealed raw consuming of snakes for treatment of tuberculosis, syphilis and joint pain, for tonics and for the belief of special nutrition among very limited group of Korean population. Because of this kinds of mode of infection, comprising four fifths of all cases, the majority of cases detected were male adult consisting of about 70% of total cases. And drinking of untreated water in rural area where no protective, sanitary measures for water sources were provided in the past, seems another important causes of infection especially in women and children in Korea. Thus it may be concluded that sparganosis in Korea is concluded by eating of infective stages per os voluntarily or involuntarily, but not through the direct invasion. Clinically, subcutaneous mass or lump was the most frequent problem in those patients and those masses were associated with inflammatory signs. By the anatomical location of the lesion, some peculiar manifestations could be developed as in orbital, abdominal, urethral, ureteral and vertebral cases. And the lesions could be complicated by haemorrhage or abscess formations. The larval worms hitherto collected in Korea has been identified tentatively as Sparganum mansoni because neither branched larvae nor Sparganum proliferum were ever reported.
