天津口岸1例输入性疟疾个案调查报告分析

Analysis on a Case Investigation of Imported Malaria at Tianjin Port

目的 调查1例境外输入性疟疾的流行病学特征及发病特点,为制定针对性防控策略提供参考。方法 收集患者流行病学个案信息资料并采集血液样本,利用血涂片镜检、疟原虫抗原检测卡和实时荧光PCR法进行实验室检查。结果 患者血常规显示白细胞计数降低,淋巴细胞和中性粒细胞绝对值降低,肝功能异常升高,疟原虫抗原检测卡和实时荧光PCR法检测结果均为恶性疟原虫阳性,初步诊断为恶性疟。结论 继续以来自重点疫区人员疟疾监测为防控重点,加强国际旅行卫生保健中心在传染病监测中的作用,加强口岸相关部门联防联控,防止输入性传播,巩固消除疟疾成果,确保口岸的公共卫生安全,维护社会稳定。

Objective To investigate the epidemiological and pathogenic characteristics of an imported malaria case,and to provide reference for formulating targeted prevention and control strategies.Methods Epidemiologi-cal case data and peripheral blood were collected,and blood smear microscope exam,colloidal gold+method and PCR were performed.Results Blood routine showed decreasing white blood cell count,decreasing absolute value of lymphocytes and neutrophils,and increasing abnormal liver function.The results of colloidal gold+rapid detec-tion and PCR were positive for Plasmodium falciparum,and the preliminary diagnosis was Plasmodium falciparum.Conclusion We should continue to focus on malaria surveillance among returning personnel,strengthen joint pre-vention and control by relevant departments at ports,prevent importation and re-transmission,consolidate the re-sults of malaria eradication,ensure public health safety at ports,and maintain social stability.
