Abstract：

        Dengue fever, a mosquito-borne viral infection, poses a significant health risk in Kaohsiung City, Taiwan. Cianjhen district, a high-risk area, experienced an outbreak from August 29 to October 2, 2022, with 18 confirmed cases. Local authorities implemented a multi-pronged approach to control the outbreak. This included intensified vector control measures, such as breeding-site elimination, chemical spraying, and container reduction, within a 150-meter radius of identified cases. Furthermore, enhanced communication and coordination through frequent meetings at the district and city levels ensured a unified response. Daily vector surveillance provided continuous monitoring of the outbreak. This prompt and coordinated intervention strategy successfully controlled the outbreak within 34 days. The experience offered valuable insights for future dengue prevention and control efforts, highlighting the importance of rapid action and collaborative strategies.
