目的了解刚果(金)人群感染疟原虫的种类及中国维和二级医院与刚果(金)医院实验室显微镜检查疟原虫的报告方法,为在非洲执行维和医疗任务的相关人员提供必要的建议。方法对收集的1 506份标本制作厚、薄血涂片,瑞氏染色后检查疟原虫感染状况;分别采用中国维和二级医院与刚果(金)当地医院镜检疟原虫的报告方法1对120例疟原虫阳性标本进行报告并比较;对50例维和医院报告阳性标本,采用不同血量和推片角度制作血涂片,比较对当地医院报告方法2的影响。结果刚果(金)疟疾以恶性疟为主。采用维和医院报告方法的准确率显著高于当地医院报告方法1(P<0.05)。不同的标本量和推片角度对当地医院疟原虫感染报告方法2的报告结果有显著影响(P<0.05)。结论刚果(金)人群中主要流行恶性疟;中国维和部队二级医院镜检疟原虫的报告方法优于刚果(金)当地医院的报告方法。
Objective To understand the types of Plasmodium infection in the DRG population and the reporting method of microscopic examination of malaria parasite in the peacekeeping hospitals of China and Peace Hospital of the Democratic Republic of the Congo (DRC) so as to provide the necessary advice for those involved in peacekeeping medical operations in Africa. Methods A total of 1 506 specimens were collected for thick and thin blood smear. The infection status of Plasmodium was examined after Wright’s stain. The method of mirroring Plasmodium at the two hospitals of China Peacekeeping and DR Congo Positive cases of Plasmodium were reported and compared; 50 cases of peacekeeping hospitals reported positive specimens, using different blood volume and push the angle of making blood smear, compare the impact of the local hospital method 2. Results Congo (gold) malaria dominated by falciparum malaria. The accuracy of using the peacekeeping hospital’s reporting method was significantly higher than that of the local hospital’s reporting method 1 (P <0.05). Different specimen sizes and push-tab angles had a significant effect on the reported results of Method 2 of Plasmodium infection in local hospitals (P <0.05). Conclusions Majority of the DRG population is endemic to P. falciparum. The reporting method of microscopic malaria parasites in the secondary hospitals of the Chinese peacekeepers is superior to that of the local hospital in Congo (DRC).
