2006年中国登革热疫情监测分析

Dengue fever surveillance in China, 2006

  • 摘要: 目的 分析中国(未包括香港、澳门和台湾地区)登革热疫情监测资料,为加强登革热的预防控制提供科学依据。方法 对2006年全国网络直报登革热疫情及登革热监测点资料用描述流行病学方法进行统计分析。结果 2006年全国共14个省份报告登革热病例1044例,无死亡报告。除广东省有本地感染外,其他地区均为输入性病例;输入性病例全年均有分布,主要来自东南亚和美洲等地区;输入病例最多的前3位国家是柬埔寨、缅甸和新加坡。广东省登革热多点暴发,发病时间集中在8-11月。媒介伊蚊监测显示广西、海南、云南地区所有监测点和福建省(86.7%)、广东省(55.8%)布雷图指数(BI)均超过5的安全水平;尤其6-10月,BI普遍较高。福建、广东、云南和广西地区媒介蚊种均为白纹伊蚊,海南省媒介为白纹伊蚊和埃及伊蚊。监测点健康人群登革热抗体阳性率为0%~14.5%。开展病原学检测的监测点没有从媒介伊蚊中检测到登革病毒核酸或分离到病毒。 结论 中国南方登革热监测省份具有登革热流行的媒介伊蚊和易感人群,夏秋季节可由输入病例引发本地暴发流行。应普遍建立灵敏的早期登革热预警监测系统,早期发现病例,防蚊灭蚊,控制疫情的扩散。

     

    Abstract: Objective To analyze the surveillance data of dengue fever in China (excluding Hong Kong, Macao and Taiwan) for providing evidence for the prevention and control of the disease. Methods Descriptive epidemiological method was used to statistically analyze the dengue fever data reported through the National Network Direct Reporting System and the surveillance results in 2006. Results In 2006, a total of 1044 cases of dengue fever were reported in 14 provinces, and no death case was reported. Except the indigenous cases in Guangdong,the cases in other areas were imported ones, which occurred all the year around and were mainly from South-East Asia and America regions. Cambodia, Myanmar and Singapore were the first three countries where the most imported cases came from. Vector surveillance to Aedes indicated that Breteau Index (BI) was above 5 (the safety level) in all surveillance spots in Guangxi, Hainan and Yunnan, and in most surveillance spots in Fujian (86.7%) and Guangdong (55.8%), especially during June to October,the BI was much higher. The vector in Fujian, Guangdong, Yunnan and Guangxi was Aedes albopictus, and the vectors in Hainan were Aedes albopictus and Aedes aegypti. The positive rate of dengue fever antibody among healthy people at surveillance spots ranged from 0% to 14.5%. No dengue virus nucleic acids was detected and no dengue virus was isolated from the vector Aedes at the surveillance spots which conducted etiological detection. Conclusion Mosquito vectors and susceptible population exist in the monitored provinces of southern China, imported case in summer and autumn may cause indigenous outbreak. It is important to set up sensitive dengue fever surveillance system for the early-warning, detect cases early and conduct mosquitoes control activity.
