摘要: 目的 针对南京市江北新区1例输入性登革热病例,开展蚊媒监控,消除传播风险,验证和完善防控措施。方法 按照中国疾病预防控制中心《登革热防治技术指南》,对南京市江北新区2018年6月报告1例登革热病例后开展应急监测和流行病学调查。结果 经实时荧光定量PCR法确诊1例来自柬埔寨的输入性登革热病例。用布雷图指数(BI)法和双层叠帐法监测蚊媒密度,核心区BI和帐诱指数分别从6月15日的3.24和6.00只/(顶·h)降至7月2日的0.44和0.75只/(顶·h),警戒区均BI<5和帐诱指数<2,且随访未发现新病例。结论 疫情处置及时,防控措施落实到位,未发生二代病例。

Abstract: Objective To investigate a case of imported dengue fever in Jiangbei New District of Nanjing, China, and to conduct vector mosquito surveillance and control response for testing and harmonizing the dengue prevention and control measures. Methods According to the requirements in the technical guidelines for the prevention and treatment of dengue fever issued by Chinese Center for Disease Control and Prevention, emergency surveillance and epidemiological investigation were performed for an imported dengue case in June 2018. Results A case of imported dengue fever from Cambodia was confirmed by quantitative real-time PCR. Breteau index (BI) and the double mosquito net method were used to monitor the density of mosquito vectors. From June 15 to July 2, the BI in the core area decreased from 3.24 to 0.44, and the net trap index decreased from 6.00 to 0.75 mosquitoes/(net·h). BI<5 and the net trap index <2 were observed in the warning area. No new cases were found during follow-up. Conclusion Epidemic management was given in a timely manner, and vector surveillance and control were fully implemented. No secondary cases were observed.
