Abstract
Background: Mosquito-borne diseases in the Republic of Korea have a unique epidemiology due to the rapid improvement in hygiene and economic status, occurrence of four distinct seasons, and separation from North Korea owing to the political situation. Therefore, we aimed to analyze and review the epidemiology of mosquito-borne diseases in Korea. Methods: The incidence and geographical distribution of malaria, Japanese encephalitis (JE), Zika virus infection, chikungunya fever, and dengue fever were investigated using data from the Korean Centers for Disease Control and Prevention. Lymphatic filariasis and West Nile fever, which have rarely been reported in Korea, have also been discussed in this literature review. Results and Conclusions: Malaria disappeared from Korea in 1979, but since its re-emergence in 1993 there has been constant occurrence with local transmission. In Korea, vivax malaria is the only prevailing disease, and the clinically problematic chloroquine resistance has not been reported. The incidence of JE has greatly reduced since the introduction of the national vaccination program for children in 1985. However, the incidence of JE has been increasing recently, especially in adults >40 years of age. Filariasis, which was previously endemic to Jeju Island and the southern coastal area, has not been reported since 2002. Although there are numerous imported cases with increasing overseas travel, there are still no indigenous cases of Zika, chikungunya, and dengue fever reported in Korea. The West Nile virus was isolated from migratory birds, but there has been only one imported human case to date.
