The current status and future prospects of parasitic infections in Korea is briefly reviewed. Soil-transmitted helminth infections including ascariasis, trichuriasis, and hookworm infections decreased remarkably. owing to the national control activities excuted by the Korea Association of Health Promotion(formerly Korea Association of parasite Eradication) using mass heath education. Important recent trends include reemergence of vivax malaria since 1993, persistence of food-borne trematode infections including clonorchiasis and intestinal trematode infections, increased detection of zoonotic parasitosis, close-up of infection with opportunistic parasites including cryptosporidiosis, toxoplasmosis, and pneumosytosis, increase of imported tropical infectious disease, appearance of new parasitic disease such as gymnophalloidiasis, and increase of accidental infections with free-living amoebae. These trends represent greatly changed overall patterns of parasitic infections in Korea.
