“…Indeed, the climatic conditions can significantly impact mosquito activity and, consequently, the potential of malaria transmission and infection (Shin et al 2008). Of significant note is the confirmation that Ganghwa-gun stands out as the highest incidence of malaria cases in Incheon MC (Kim et al 2021). Various regional factors, including topography, aquatic features, land utilization, and outdoor human activities, are instrumental in shaping the distinct characteristics of malaria incidence (Pope et al 2005;Vanwambeke et al 2007;Moshi et al 2018;Fornace et al 2021).…”

Malaria, a globally significant mosquito‐borne infectious disease, re‐emerged in the Republic of Korea, and manifested annually in regions close to the demilitarized zone. Notably, Incheon Metropolitan City has witnessed an alarming upswing in malaria infections in recent years, drawing attention to this public health issue. This research was conducted to catch spatio‐temporal and ecological landscape encompassing malaria patients and mosquito vectors in Incheon over the past decade. The top two incidences of malaria cases were found in Ganghwa‐gun and Seo‐gu, an occurrence potentially attributed to their geographic proximity to North Korea. Furthermore, the incidence of malaria infections displayed a seasonal pattern commencing in March, reaching its peak between June and August, and decreasing to a minimum in November. A correlation was noted between prevalence of malaria cases and number of mosquito breeding sites, such as ponds and rice fields within the region. Collectively, these research outcomes underlined the importance of systematically and holistically advocating mosquito elimination measures to enhance the efficacy of malaria eradication policies. These measures encompass the establishment of a robust mosquito outbreak surveillance system, targeted control of vector mosquitoes, residual pesticide spray, management of mosquito breeding sites, and adoption of repellents during outdoor activities.

Human malaria, transmitted by Anopheles mosquitoes, is the most predominant mosquito-borne disease that is responsible for hundreds of thousands of deaths worldwide each year. In the Republic of Korea (ROK), there are currently several hundred malaria cases annually, mostly near the demilitarized zone (DMZ). Eight species of Anopheles mosquitoes are currently known to be present in the ROK. Similar to other major malaria vectors in Africa and India, it is very challenging to morphologically differentiate Anopheles mosquitoes in the ROK due to their extremely similar morphology. In this study, wing geometric morphometrics (WGM) were used to differentiate the eight Anopheles species collected at six locations near the DMZ, Seoul and Pyeongtaek from April–October 2021. Phylogenetic analysis was also performed using cytochrome c oxidase subunit 1 (COI), internal transcribed spacer 2 (ITS2), and tyrosine hydroxylase (TH) genes for comparison with WGM analysis and to infer evolutionary relationships. The results of cross-validation (overall accuracy = 74.8%) demonstrated that species identification using WGM alone was not possible with a high accuracy for all eight species. While phylogenetic analyses based on the COI region could not clearly distinguish some species, the analysis based on ITS2 and TH was more useful for resolving the phylogenetic correlation of the eight species. Our results may improve Anopheles species identification strategies for effective identification and control of malaria vectors in the ROK.
