The first human case of Trichinella spiralis infection in Korea

Three cases of human infection by Trichinella spiralis were first confirmed by detecting encysted larvae in the biopsied muscle in December 1997, in Korea. The patients were one 35-and two 39-year-old males residing in Kochang-gun, Kyongsangnam-do. They had a common past history of eating raw liver, spleen, blood and muscle of a badger, Meles meles melanogenvs, and complained of high fever, facial and periorbital edema, and myalgia. Hematologic and biochemical examinations revealed leukocytosis and eosinophilia, and highly elevated levels of GOT, GPT, LDH and CPK. In the gastrocnemius muscle of a patient, roundly coiled nematode larvae were detected. The larvae measured 0.775-1.050 (av 0.908) mm in length, and 0.026-0.042 (av. 0.035) mm in maximum width. The specific IgG antibody levels in three patients' sera were significantly higher when compared with those of normal controls. The patients were treated with flubendazole and albendazole for 15-30 days, and discharged at 13-34 days post-admission. From the above findings, it was confirmed that T. spiralis is present in Korea, and the badger plays a role of as the natural host.
