Recent results of mass stool examination for parasitic infections revealed 0.01-0.0001 percent of Paragonimus egg positive rate in Seoul school-children. This survey was carried out to understand the infection status of intermediate hosts and their relations to human paragonimiasis in Seoul. Twelve mountainous streams in the outskirts of Seoul were surveyed. From all streams, Semisulcospira libertina, the snail intermediate host was not detected. From 7 streams 132 crayfishes, Cambaroides similis, the second intermediate host were collected. From them no metacercaria was found. The results indicated that crayfish in district of Seoul is no more an infection source of paragonimiasis. Possible factors related with the ecology of intermediate hosts were briefly discussed from the epidemiological view point.
