| 目的 分析2005-2007年中国登革热监测资料,描述中国登革热流行现状、疾病分布和特征.方法 对2005-2007年全国疾病监测信息报告管理系统网络直报的登革热病例资料及国家登革热监测点的监测资料,用描述性流行病学方法进行统计分析.结果 3年全国共报告登革热病例1623例,死亡1例.其中,实验室诊断1356例,临床诊断267例.输入性病例151例,占报告病例总数的9.3%;本地感染病例1472例.全国仅广东和福建省的9个地市报告本地感染疫情,其他省区均为输入性病例,输入地区主要为东南亚国家.夏季南方省份的蚊媒密度仍然较高,有84.6%的布雷图指数(BI)>5,约72.2% BI≥10.监测点未从蚊媒中分离到登革病毒,但广东省曾检测到病毒核酸.结论 国内本土持续性登革热流行尚未有效建立,但输入病例的威胁逐年增加.媒介伊蚊的广泛分布和较高的伊蚊密度、健康人群较低的抗体阳性率以及难以避免的登革热输入威胁使中国南方部分地区具备了发生登革热本地爆发性流行的潜在条件,有必要在重点地区建立蚊媒综合监测和控制系统. |

| Objective To provide scientific evidence for prevention and control program on dengue fever through analyzing the situation of dengue fever in China,from 2005 to 2007.Methods Data was collected from Internet-based National Notifiable Infectious Disease Reporting System,National Enhanced Dengue Fever Surveillance system and field investigation on dengue outbreaks,described and analyzed with descriptively and by SPSS statistical software.Results There was a total number of 1 623 dengue cases(including 1356 laboratory confirmed cases and 267 probable cases)and 1 death case reported in China from 2005 to 2007.Among the identified cases,151 were imported from foreign countries as the Southeast Asian countries,accounting for 9.3%,while the rest 1472 cases were reported from local infections,identified only in 9 cities from Guangdong and Fujian provinces.Data from the monitoring program on Aedes Mosquitoes indicated that:The indicators of BI from 84.6% of the sentinels were over 5,and BI from 72.2% of the sentinels were over 10.This index was especially at a higher level during summer in the southern areas of China.Aedes albopictus was found in all the sentinel sites while Aedes aegypti was only found in Hainan and in limited counties of Guangdong.No dengue virus was isolated from mosquito vectors collected from national sentinel sites, whereas positive results had been detected by PCR test in Guangdong province.Conclusion It was assumed that a sustainable local circulation of dengue virus had not yet been established successfully in Mainland China according to the surveillance data.However,more local outbreaks reported in Guangdong and Fujian with the wide distribution and high-level density of aedes mosquito,low antibody level in healthy population and the increasing number of imported dengue cases, there is a potential of Dengue outbreaks in southera China.An integrated mosquito vector monitoring and management system is needed in hish risk area to reduce the transmission of dengue fever. |
