广东省潮州市登革热防控试点研究

目的通过开展综合干预措施,评估已开展措施对登革热防控工作的可行性和效果评估,摸索出一套适合潮州市实际情况的综合防控策略。方法在示范区建立登革热防控工作领导机制,明确职责、落实措施,形成多维度的宣传动员模式,建立和管理区域性消杀队伍,依据抗药性监测结果开展消杀。对2016年创建的示范区西新街道以及对照区的布雷图指数、幼虫或卵密度（诱蚊诱卵器）、成蚊密度（灯诱）、登革热发病数指标进行对比分析。结果在创建示范区前,2015年示范区和对照区布雷图监测结果均长期高于5,且两者差异无统计学意义（P>0.05）。在创建示范区后,2016年示范区内的布雷图指数、诱蚊诱卵器指数能控制在5（符合防控要求）以下,低于同期的对照区,且和对照区布雷图指数、诱蚊诱卵器指数监测结果差异有统计学意义（P<0.05）。2016年示范区诱蚊灯指数总体趋势下降,高峰出现在9月上旬,此后逐渐下降为0。示范区的病例从2015年468例下降到2016年登革热病例零报告。结论登革热防控示范区以政府主导,群防群控,全民动员起来,平时注重干预,达到了有效防控登革热的目的。但仍需进一步完善登革热防控长效机制并在全市推广,动员社会一切力量开展孳生地清除活动,防蚊灭蚊。

A pilot study on dengue fever prevention and control in Chaozhou Municipality,Guangdong

ObjectiveTo assess the feasibility and effectiveness of conducted measures of dengue fever prevention and control, so as to find out a suit of suitable comprehensive prevention and control strategy in Chaozhou City. MethodsIn the demonstration area, the leadership mechanism of dengue prevention and control work was established. The responsibilities and implement measures were clarified. A multidimensional model of propaganda and mobilization was formed. The establishment and management of regional disinfection team were performed. According to the monitoring results of resistance, the disinfection was carried out. In 2016, the Breteau index, egg or larva density (mosquito ovitrap), mosquito density (light), and dengue incidence were contractively analyzed in the demonstration area of West Street and the control area. ResultsIn 2015, before the establishment of the demonstration area, in the demonstration area and control area, the long-term monitoring showed that the Breteau indexes were both higher than 5, and there was no significant difference between the two areas. After the establishment of the demonstration area in 2016, in the demonstration area, the Breteau mosqovitrap index was controlled in 5 (in accordance with the requirements of prevention and control) or less, which was lower than that in the control area in the same period (P<0.05). In 2016, the overall trend of the mosquito trap lamp index declined in the demonstration area, and the peak appeared in the early September, and then gradually decreased to 0. The dengue fever cases dropped from 468 cases in 2015 to zero in 2016 in the demonstration area. ConclusionsAll the work in the dengue fever prevention and control demonstration area is dominated by the government and the mass prevention and control is carried out, therefore, the goal of effective prevention and control of dengue fever is achieved. However, it is necessary to further improve the long-term prevention and control mechanism of dengue fever in the future.
