Recently, influenced by high temperatures, the number of malaria-carrying vectors in South Korea has surged sharply, and the number of malaria patients nationwide has exceeded 320, causing public concern. The latest data released by the Korea Disease Control and Prevention Agency on the 28th shows that the density of mosquitoes transmitting malaria this year is more than twice that of last year, and they account for 60% of all mosquito species monitored. Malaria patients in the Seoul area account for about 18% of the national total. The intense heat has led to a sharp increase in the number of Anopheles mosquitoes, and rising temperatures across the country have gradually created a favorable environment for their survival. Currently, the Korea Disease Control and Prevention Agency has issued a malaria alert nationwide and, for the first time, included 13 districts of Seoul City in the risk areas. It has also released information reminding the public to minimize going out at night, wear long sleeves and pants and apply mosquito repellent when walking at night to avoid mosquito bites.
