ABSTRACT
Malaria, one of the compulsory notifiable diseases, has been diappeared from Korea based on that fact no notification on malaria case was received from local health agencies during the last decade or so. Recently, Indigenous malaria has been re-emerged since 1993 and 549 cases was notificated till 1996. We conducted a surveillance system on the resurgent malaria outbreaks in the northern area of Kyonggi Province around the Imjin River. Malaria Surveillance Networks(MSNs) were established in Paju and Yoncheon between August 1996 and December 1996. When a febrile patient visits a clinic or a hospital, clinician takes a blood sample and refer to district malaria laboratory for the sample. The blood sample is examined in the malaria laboratory(public health center), and if malaria parasites are found, a radical or curative treatment is offered to patients. MSNs took 94 febrile cases and identified 23 malaria cases(24.5%). All malaria cases were infected by the indigenous vivax malaria. In Paju, 14 of 62 febrile cases(22.6%) were malaria outbreaks and 9 of 32 febrile cases(28.1%) in Yoncheon. In Korea resurgent malaria, malaria surveillance system should be operated for a program based on the district public health center with the coupled laboratory and dispensary.
