Epidemiological surveys concerning cestodes of medical importance in Korea have been sporadically reported by many workers. Among various parasitic infections, cestode infections occur less frequently than other helminthiases, but they often cause serious clinical complications. Cestodes reported so far in Korea belong to the Order Pseudophyllidea or Cyclophyllidea (Subclass Cestoda), i.e., Diphyllobothrium latum, D. yonagoense, Spirometra erinacei, sparganum, Hymenolepis diminuta, H. nana, Mesocestoides lineatus, Taenia saginata, T. solium, metacestode of T. solium (cysticercus), and Echinococcus granulosus. The present paper is a brief review of the literature concerning these cestode infections in Korea. Taeniases by T. saginata or T. solium are prevalent cestode infections in Korea, and cysticercosis by T. solium often reveals serious clinical manifestations. H. nana infection is relatively rare, showing 0.22% egg positive rate in a nationwide survey in 1986. Sparganosis by the plerocercoid larva of Spirometra is not an uncommon cestode infection in man, and 16 kinds of animal hosts including the snakes and frogs have been reported. D. latum infection has been an uncommon intestinal parasitosis, but it tends to increase nowadays. Most of human hydatidosis cases have been recognized as imported ones from outside Korea, but one case was proven indigenous. Other 4 kinds of cestodiases are extremely rare in Korea and only a few cases have been recorded.
