Abstract
PURPOSE
In Korea, vivax malaria re-emerged in 1993 and the outbreak continued in several areas near the DMZ until now.
This study was conducted to define the epidemiologic pattern of malaria in Korea and to examine the changes comparing to the one in 1999.METHODS We collected information about civilian, veteran patients through the National malaria surveillance system and soldier from the Ministry of National Defense. We analyze epidemiological characteristics of malaria by groups (civilian, veteran, soldier).RESULTS The reported cases of malaria in 2000 were 4,142 that number is an increase of 14% in numbers compared with those of 1999's. Most of cases occured in 17 counties nearby DMZ and from May to October(98.7%) seasonally. The incidence rates (per 100,000) in 2000 by residence were 17.0 in Gangwon-Do, 15.5 in Incheon Metropolitan city, 10.3 in Gyeonggi-Do was dereased. The risk area in 2000 were 17 counties located nearly DMZ and the high risk area were 5 counties where the incidence rate greater than 100. In case of civilian and veteran, the time required to diagnosis from onset of symptom was 8.1 days on the average.CONCLUSION Epidemiologic pattern of malaria in 2000 did not differ from the one in 1999. Et showed regional spread (increasing risk area) but incidence rate was lowered in the high risk area of 1999. And it is necessary that we pay more attention to Gangwon-Do and Incheon metrocity to reduce the incidence rate in 2001.

The highest incidence rate was shown in 5-9 year-old group. Especially the south area of Jeju Island, called as Namjejugun, had the major epidemic occurrence.CONCLUSIONS The huge and chronic epidemic of Shigellosis was confirmed. The nature of this epidemic suggested that the endemic occurrence had been existed in Jeju Island.
