摘要
目的结合南宁市2019年登革热暴发疫情资料,比较两个城区布雷图指数法的伊蚊监测数据,为完善伊蚊监测工作提供参考。方法收集报告登革热例数最多的江南区和作为登革热媒介国家级监测点的兴宁区2019年登革热暴发疫情病例资料和当年的伊蚊布雷图指数法监测资料,采用描述性流行病学方法,分析比较不同情境下伊蚊监测数据差异。结果江南区报告病例370例,首例病例发病日期是2019年5月21日,病例数到达25%、50%、75%、100%的时间分别是9月27日、10月6日、10月15日和11月28日,日最高病例数19例;兴宁区报告病例56例,首例病例发病日期为2019年9月14日,病例数到达25%、50%、75%、100%的时间分别是10月3日、10月17日、10月29日和11月12日,日最高病例数4例;两个城区的布雷图指数均在9月份达到最高值,江南区每个月的布雷图指数均值均<5,兴宁区除了11月份其他月份的布雷图指数均值均>5;江南区在废品站和居民区监测到的布雷图指数最高,分别为4.94、4.56,医院的布雷图指数最低,为0.61;兴宁区在花鸟市场和废品站的布雷图指数最高,分别为15.11、11.69,工地和公园布雷图指数最低,分别为0.22、0.28;江南区应急监测中居民区、学校灭蚊前的布雷图指数9.98、11.67,均明显高于灭蚊后的2.89、0.67,兴宁区应急监测中居民区灭蚊前的布雷图指数11.57明显高于灭蚊后的2.16。结论两个城区2019年的伊蚊监测数据基本反映了登革热传播媒介的季节变化与登革热暴发疫情的时间逻辑关系,但还不能对登革热暴发疫情起到预警作用,需要持续提高病媒监测工作质量。
Objective To compare the surveillance data of Aedes vector in two urban districts by combining with the data of dengue fever outbreaks in Nanning City in 2019,and to provide references for improving local surveillance of Aedes mosquitoes.Methods We collected the data about cases from dengue fever outbreaks in 2019 and the surveillance data of Aedes vector based on Breteau index method in Jiangnan district which had the most cases of dengue fever and Xingning District which served as a national surveillance site of Aedes vector.Descriptive epidemiological methods were used to analyze the difference of the surveillance data of Aedes vector in the two districts.Results There were 370 cases of dengue fever reported in Jiangnan District,and the date of onset of the first case in 2019 was May 21.The dates when the number of cases reached 25%,50%,75%and 100%were September 27,October 6,October 15 and November 28,respectively.The daily maximum number of cases was 19.The number of cases reported in Xingning District was 56,and the date of onset of the first case in 2019 was September 14.The dates when the number of cases reached 25%,50%,75%and 100%were October 3,October 17,October 29 and November 12,respectively.The daily maximum number of cases was 4.Both the districts had their highest Breteau index in September.The monthly mean Breteau indexes in Jiangnan District were all<5.Except for November,the monthly mean Breteau indexes in other months in Xingning District were all>5.Breteau indexes by surveillance in waste stations(4.94)and residential areas(4.56)in Jiangnan District were the highest,while Breteau index by surveillance in hospitals(0.61)was the lowest.Breteau indexes by surveillance in flower and bird markets(15.11)and waste stations(11.69)in Xingning District were the highest,whereas Breteau indexes by surveillance in construction sites(0.22)and parks(0.28)were the lowest.In Jiangnan District,Breteau indexes in residential areas and schools in the emergency monitoring before vector control were significantly hi
