南京地区6例输入性登革热病例的处置分析

Investigation and disposal for six imported cases of Dengue fever in Nanjing

目的分析南京地区近年来输入性登革热病例处置情况,为相关部门的公共卫生决策提供建议。方法使用描述性流行病学方法分析2012—2015年南京地区6例输入性登革热病例的发现及处置情况,分析存在的公共卫生风险。结果 4名病例为入境时处于潜伏期,无症状,入境后因出现发热等症状就医而被确诊,其中3例呈聚集性,主要的公共卫生风险是诊断及对症治疗延迟。2名病例为入境时有发热症状,在口岸被发现,主要的公共卫生风险是实验室检测技术支持体系不完善,可能造成后续处置滞后。结论针对公共卫生风险,应重视现场流行病学的应用,实施境外传染病的"关口前移",提高医疗人员对登革热基本诊疗常识掌握水平,做好部门之间的联防联控。

Objective To investigate the imported cases of Dengue fever during the past four years in Nanjing,and to provide suggestions for government strategy making about public health. Methods The diagnosis and disposal of the six imported cases of Dengue fever during 2012-2015 had been analyzed by means of descriptive epidemiology.The risk factors about public health throughout the disposal procedure were summerized. Results Four cases were in the period of incubation without symptoms at port,they developed typical symptoms such as fever after entry. Three of the four cases consisted of clustering. The main risk factors were the delay of diagnosis and treatment. The other two cases were febrile during entry at port,they were detected by the infrared surveillance system. The main risk factor was the delay of disposal caused by the incompetent detection technique. Conclusion What we need to do in response to these risk factors is to pay more attention to field epidemiology,to implement prevention beforehand beyond the borders,to improve the level of mastery about Dengue fever in medical personnel,and to put joint control and prevention into effect between different departments.
