Abstract: Objectives: We analyzed malaria cases and cluster outbreaks in the capital city between 2022 and 2024 to provide baseline data to guide effective prevention and response strategies. Methods: All malaria cases reported in the Integrated Disease Control Information System between January 1, 2022, and December 31, 2024, were included. Annual trends, demographics, regional distributions, and case clusters were analyzed. Clusters were defined as multiple cases occurring within 14 days and within 1 km of suspected infection sites based on 2024 Malaria management guidelines. Spatial analysis was conducted using QGIS version 3.34. Results: In 2024, 620 malaria cases were reported in the capital city, representing 94.1% of total cases nationwide. This number represents a slight decrease from 2023, but a 78.7% increase from 2022. A total of 47 case clusters were identified, including five (10.6%) in military units. Clusters were concentrated in high-risk areas near the North Korean border, especially in northwestern Gyeonggi, Ganghwa-gun, and Incheon. Primary risk factors included residence (57.8%), work (12.9%), military service in high-risk areas (12.9%), and outdoor leisure activities including travel and exercise. Conclusions: The post-coronavirus disease 2019 rise in malaria incidence is linked to resumption of social activities and enhanced surveillance. The capital region remains the focal point of domestic transmission, highlighting the need for regional and population-specific control measures. Targeted strategies for military personnel and outdoor workers are critical to achieve Korea's national malaria elimination by 2030 goal.
