【摘要】 目的 分析上海市松江区登革热流行病学特征，为登革热防治提供科学依据。方法 通过国家疾病监测信息报告管理系统获得2014—2020年松江区登革热病例信息，用描述性流行病学方法分析病例的发病时间、空间、人群分布等流行病学特征。结果 2014—2020年松江区累计报告登革热病例20例，均为输入性病例，无本地病例发生；无死亡病例。主要来自东南亚，占所有报告病例的95.0%(19/20)。时间分布呈单峰，以7—8月为高峰。男女性别比为4∶1，发病年龄中位数37岁，以青壮年为主（65.0%）。职业以公司职员（35.0%）、商业服务人员（20.0%）和工人（20.0%）为主。全区15个街道（镇）中7个有登革热病例报告。20例病例发病到确诊的时间间隔中位数为6 d。实验室检测检出DENV-1型和DENV-2型，以DENV-2型为主（71.4%）。结论 上海市松江区登革热疫情以输入性病例为主，有明显的季节性。登革热疫情防控的重点是严防输入，控制本地疫情的发生与流行。更多还原

【Abstract】 Objective To analyze the epidemiological characteristics of dengue fever cases in Songjiang District of Shanghai for scientific evidences in prevention and control of this infection. Methods Cases of dengue fever reported in Songjiang District were retrieved from the National Disease Surveillance Information System during 2014-2020. Descriptive epidemiological method was used to analyze the epidemiological properties, including the time, space and population distribution of the cases. Results Totally, 20 dengue fever cases were reported in Songjiang District from 2014 to 2020, all of which were imported cases. There were no local cases and no deaths. The cases were generally imported from Southeast Asian countries, which accounted for 95.0% of all reported cases(19/20). Temporal distribution presented in unimodal fashion, and was peaked in July and August. The male to female ratio was 4∶1, and the median age was 37 years old for the infections, with the young and middle aged being dominant(65.0%). Occupation with dengue infection was associated with company employees(35.0%), business services(20.0%)and workers(20.0%). The imported cases were reported from 7 of the 15 blocks/towns within Songjiang District. The interval of median days for the 20 cases was 6 d from onset to final diagnosis. Laboratory studies revealed that the infection was involved in DENV-1 and DENV-2, with DENV-2 being dominant(71.4%). Conclusion The dengue fever epidemic in Songjiang District of Shanghai is dominated by imported infection, and evidently presents in seasonal fashion. The findings suggest that the prevention and control measures should be focused on management of imported infection as well as local prevalence and epidemic.更多还原
