目的 :为了解和掌握驻琼部队疟疾感染现状 ,提出今后疾疟防治工作的措施 ,旨在有效地控制疟疾发病率。方法 :选取驻琼部队中的 6个单位共 2 72 8名官兵进行了回顾性个案调查 ,同时查取自 1997年 3～ 8月间有过发热、怕冷症状的人员 312名 ,以此为对象 ,逐一采取指头血 2滴 (约 10 0 μl)做血涂片镜检 ,同时采取耳垂血 2滴 (约 10 0 μl)进行PCR检测。 结果 :在调查的 2 72 8名官兵中 ,有类似疟疾症状的共 312人 ,疑患率为 11.4 4 %。对 312人做PCR检测 ,结果有 6例阳性 ,均为间日疟 ,检出率为 1.92 % ,感染率为总调查人数的 2 .19‰ ;血涂片镜检有 3例阳性 ,检出率为 0 .96 %。结论 :疟疾的感染状况与社会经济因素、自然因素、个人防护有关 ,对驻疟疾疫区部队应加强疟疾防治工作。
Objective: To understand and grasp the status quo of malaria infection among the troops stationed in Qiongqiong and to put forward measures to prevent and control malaria in the future so as to effectively control the incidence of malaria. Methods: A total of 2 728 officers and men from 6 units in the Qiong unit were selected for retrospective case investigation. At the same time, 312 persons who had fever and cold symptoms from March to August in 1997 were investigated. Subjects, one by one to take 2 drops of finger blood (about 100 μl) blood smear microscopy, while taking two drops of earlobe blood (about 10 0 μl) for PCR detection. Results: Of the 2 728 officers and men surveyed, there were 312 malaria-like symptoms with a suspicion rate of 11.44%. PCR test was performed on 312 people, and the result was positive in 6 cases, all of which were Plasmodium vivax, the detection rate was 1.92%, the infection rate was 2.19 ‰ of the total number of investigations; 3 were positive by blood smear microscopy, The rate was 0.96%. Conclusion: The status of malaria infection is related to socio-economic factors, natural factors and personal protection. For malaria-endemic areas, the troops should strengthen malaria control.
