【Abstract】 Objective: To analyze the treatment process of an imported dengue fever epidemic in the community in order to provide basis for better control of Aedes in dengue fever foci in the future. Methods: A case of imported dengue fever was summarized, including the adult mosquito control, young mosquito control, mosquito density monitoring and household education in Xinzhuang Community, Minhang District, Shanghai in 2019, and the effect of epidemic management was analyzed. Results: After 3 consecutive days of killing mosquitoes, the density of mosquitoes dropped rapidly. After 12 days, the biting index of the core area decreased to the control threshold; after 9 days treatment, the Breteau index reached the control threshold; no new cases of dengue fever occurred in the affected area 25 days after the outbreak. According to the "Shanghai dengue fever prevention and control work plan", the emergency response of epidemic areas was terminated. Conclusion: According to the results of routine adult mosquito monitoring, the daily mosquito density control should be carried out, and the standardized, orderly and effective adult mosquitoes and mosquito larvae should be eliminated after the outbreak, and at the same time, with health promotion, the dengue fever epidemic can be controlled.更多还原
