目的调查刚果(金)维和人员疟原虫感染状况,为做好防护工作提供参考依据。方法用厚和薄血涂片法检查2005年抵达1月后的816名来自中国、巴基斯坦、印度和孟加拉国的刚果(金)维和人员疟原虫感染状况,问卷调查其工作状况、防蚊和防疟情况。结果维和人员疟原虫的感染率为29.66%(242/816);感染恶性疟原虫、间日疟原虫、三日疟原虫和卵形疟原虫的构成比依次为78.10%,7.44%,14.46%和0.00%;中国籍人员感染率明显低于其余三国(P<0.05);巴基斯坦籍人员感染率低于印度和孟加拉国籍人员(P<0.05);印度籍人员感染率低于孟加拉国籍人员(P<0.05),医务工作人员感染率明显低于其他工作人员(P<0.05)。结论恶性疟原虫是造成刚果(金)维和人员感染的主要疟原虫,不同工作性质人员间感染率有差异,应依据工作性质进行预防措施。
Objective To investigate the status of Plasmodium infection in the peacekeepers of the Democratic Republic of Congo (DRC) and provide a reference for the prevention work. Methods A total of 816 PLWHA peacekeepers from China, Pakistan, India and Bangladesh were surveyed by thick and thin blood smears for the status of malaria parasites after January 2005 and questionnaires were conducted to investigate their working conditions, mosquito prevention and prevention Malaria situation. Results The infection rate of Plasmodium in peacekeepers was 29.66% (242/816). The constituent ratios of Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae and Plasmodium ovale were 78.10%, 7.44%, 14.46% and 0.00%; the infection rate of Chinese nationals was significantly lower than that of the other three countries (P <0.05); the infection rate of Pakistani nationals was lower than that of India and Bangladesh nationality (P <0.05); the infection rate of Indian nationality was lower than that of Bangladeshi nationality (P < 0.05), the infection rate of medical staff was significantly lower than other staff (P <0.05). Conclusion Plasmodium falciparum is the major malaria parasite infected by peacekeepers in the Democratic Republic of the Congo. There are differences in the infection rates among different working staffs. Preventive measures should be taken according to the nature of the work.
