摘要:

目的 分析宁波市2005-2012年登革热病例流行病学特征, 并结合病媒生物监测数据, 分析宁波市出现登革热流行的风险。方法 采用Excel 2003软件分析宁波市登革热病例的流行病学特征;采用CO2诱蚊灯法调查宁波市蚊类种群构成及其密度。结果 2005-2012年宁波市累计报告11例登革热病例, 均为输入性病例, 其中25~50岁有8例, 男女性别比为1.75∶1。患者职业分布以商务人员为主(36.37%)。白纹伊蚊是宁波市登革热传播主要媒介蚊种。结论 宁波市白纹伊蚊广泛存在, 输入性病例逐年增多, 存在发生登革热流行的风险。应继续做好蚊类监测, 预防登革热流行的发生。

Abstract:

Objective To analyze the epidemiological features of dengue fever from 2005 to 2012 in Ningbo, China and to assess the risk of dengue fever epidemic in Ningbo given the vector monitoring data. Methods The data of reported dengue fever cases in Ningbo were collected to analyze the epidemiological features using Excel 2003. The CO2 trapping lamp method was used to determine the population structure and density of mosquitoes. Results A total of 11 dengue fever cases, all of which were imported, were reported in Ningbo from 2005 to 2012. Eight of the 11 cases were aged 25-50 years. The male?to?female ratio was 1.75∶1. Businessmen constituted the largest group (36.37%) of these cases. Aedes albopictus was the main mosquito vector of dengue fever in Ningbo. Conclusion In Ningbo, Ae. albopictus is prevalent, and imported cases increase year by year; there is risk of dengue fever epidemic. We should continue to enhance mosquito surveillance to prevent dengue fever epidemic.
