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.
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.
There was a total number of 1623 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.
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 southern China. An integrated mosquito vector monitoring and management system is needed in high risk area to reduce the transmission of dengue fever.
通过分析2005年至2007年中国登革热疫情，为登革热防控方案提供科学依据。
数据来源于基于互联网的国家法定传染病报告系统、国家登革热强化监测系统以及登革热疫情现场调查，采用描述性方法及SPSS统计软件进行描述与分析。
2005年至2007年中国共报告1623例登革热病例（包括1356例实验室确诊病例和267例疑似病例）及1例死亡病例。在确诊病例中，151例为来自东南亚等国家的输入性病例，占9.3%，其余1472例为本地感染病例仅在广东和福建9个城市发现。伊蚊监测方案数据表明：84.6%的监测点布雷图指数超过5，72.2%的监测点布雷图指数超过10。该指数在中国南方夏季尤其处于较高水平。所有监测点均发现白纹伊蚊，而埃及伊蚊仅在海南及广东部分县发现。全国监测点采集的蚊媒未分离到登革病毒，但广东省PCR检测呈阳性。
根据监测数据推测中国大陆尚未成功建立登革病毒持续的本地传播。然而广东、福建本地疫情报告增多，伊蚊分布广、密度高，健康人群抗体水平低，输入性登革病例增多，中国南方存在登革热暴发的潜在风险。高风险地区需要建立综合蚊媒监测与管理系统以减少登革热传播。
