We find out the clusters with high toxoplasmosis risk to discuss the geographical pattern in Gyodong-myeon and Samsan-myeon of Ganghwa-gun, Cheorwon-gun, and Goseong-gun, Korea. Seroepidemiological data of toxoplasmosis surveyed using rapid diagnostic tests for the residents in the areas in 2019 were analyzed to detect clusters of the infection. The cluster was investigated using the SaTScan program which is based on Kulldorff's scan statistic. The clusters were found with P-values in each region analyzed in the program, and the risk and patient incidence of specific areas can be examined by the values such as relative risk and log likelihood ratio. Jiseok-ri and Insa-ri were found to be a cluster in Gyodong-myeon and Seokmo-ri was the cluster in Samsan-myeon. Yangji-ri and Igil-ri were found to be a cluster in Cheorwon-gun and Madal-ri and Baebong-ri were the cluster in Goseong-gun. This findings can be used to monitor and prevent toxoplasmosis infections occurring in vulnerable areas.

Article Synopsis
  • Toxoplasma gondii seroprevalence is increasing in Korea, with a study assessing antibody levels in three regions: Ganghwa-gun, Cheorwon-gun, and Goseong-gun, involving 1,518 total participants in 2019.
  • The seroprevalence rates were found to be highest in Goseong-gun at 35.7%, followed by Ganghwa-gun at 28.1%, and Cheorwon-gun at 19.5%, indicating significant variation across the areas studied.
  • Findings suggest a need for further research on T. gondii in areas near the Korean demilitarized zone, along with the implementation of health policies to address
