# Malaria surveillance and alerts in South Korea > Live situation record from CLSTR: https://clstr.news/situations/malaria-surveillance-and-alerts-in-south-korea > Updated: 2026-08-13T11:11:29.000Z. Sources: 3. Developments: 2. Following a regional alert in Incheon’s Ganghwa-gun, South Korean authorities have intensified malaria surveillance and prevention efforts. Local measures include eco-friendly spraying, larvicide treatments, and the deployment of mosquito-repelling devices in high-risk areas such as parks and riverbanks. This follows a national trend where the majority of infections occur in civilians participating in outdoor activities like camping and fishing. The Korea Disease Control and Prevention Agency (KDCA) has since escalated the situation to a nationwide malaria alert. This follows the detection of Plasmodium vivax genetic material in Anopheles mosquitoes collected in the northern regions of Paju and Yeoncheon County. While domestic malaria cases have seen a decrease compared to the previous year, health officials warned that risk areas are expanding beyond the traditional concentrations near the Demilitarized Zone. Authorities noted that while extreme summer heat initially kept mosquito density lower, populations may rebound as temperatures fall. ## Timeline ### 2026-08-13: South Korea issues nationwide malaria alert South Korea has issued a nationwide malaria alert after the KDCA detected Plasmodium vivax parasites in mosquitoes collected in Paju and Yeoncheon County. 3 sources. https://clstr.news/cluster/south-korea-issues-nationwide-malaria-alert ### 2026-07-15: South Korea steps up malaria surveillance and prevention after regional alert South Korea’s Ganghwa‑gun raises a malaria alert and boosts local spraying, while the health agency reports 601 cases in 2023 and launches a 2030 eradication plan with expanded testing and treatment incentives. 2 sources. https://clstr.news/cluster/south-korea-steps-up-malaria-surveillance-and-prevention-after-regional-alert --- Cite as: Malaria surveillance and alerts in South Korea.
