Analysis of epidemiological characteristics of dengue fever outbreak of Yangjiang City in 2006

目的:分析阳江市2006年登革热暴发的流行病学特征,评价阳江市登革热监测系统的有效性及探讨应对该类事件的处理模式,为传染病的预防与控制提供参考。方法:采用回顾性流行病学调查方法对所有病例进行调查分析,用间接免疫荧光法进行登革热抗体检测,用布雷图指数进行蚊媒密度调查。结果:首例发病6月27日,末例9月2日,共发病22例,全年疫情流行曲线只在8月下旬出现1次发病高峰。布雷图指数在采取大规模的综合控制措施前最高达98.2,在采取控制措施后,蚊媒密度达到要求。结论:根据流行病学调查和实验室检测结果,可以确定该起疫情是登革热暴发流行。采取整治环境卫生、迅速杀灭成蚊、清除积水和隔离治疗病人等综合措施后,该疫区的疫情在较短时间内得到有效控制。

Objective： To analyze the epidemiological characteristics of outbreaks of dengue fever of Yangjiang City in 2006, to evaluate the effectiveness of the monitoring system and explore the handling of such cases to deal with models that provides reference for the prevention and control of infectious diseases. Methods：Apply the retrospective epidemiological survey methods to investigate all cases of analysis and use Bretean index to survey the density of mosquito - borne by indirect immunofluorescence antibody test for dengue fever. Results： In 22 cases, the first incidence in the June 27, at the end of cases appear in the September 2. And the epidemic curve of the year only formed in late August and appear one peak. The Breteau index is up to 98.2 before, but after taken the control measures, the density of mosquito - borne meets the requirement. Conclusion： According to the epidemiological investigation and laboratory test results, it can make sure that the situation is an outbreak of dengue fever epidemic. And taken to restore environmental health, quickly kill adult mosquitoes, removing stagnant water and isolation of comprehensive measures, such as the treatment of patients, the disease infected areas in a relatively short period of time been effectively controlled.
