We examined stools of 113 soldiers of Korean Army in Whachon-gun, Korea in 1992. The eggs of Clonorchis sinensis (7/113) and Metagonimus sp. (3/113), and cysts of Giardia lamblia (4/113) were detected. No eggs of soil-transmitted helminths were found. Most of the Clonorchis-infected soldiers (6/7) were recruited from Kyongsangnam-do.
