Objective: To investigate and analyze the Congo (DRC) peacekeepers and local residents Plasmodium infection status; compare Chinese peacekeeping and two hospitals and Congo (gold) microscopic examination of Plasmodium hospital laboratory reporting methods. Aims of the Congo (gold) anti-malaria mosquito peacekeepers to provide the necessary recommendations to reduce parasite infection; looking better for the local hospital laboratory reporting methods Plasmodium infection. Methods: The combination of thick and thin blood smear Wright stain method for detecting arrival of Congo (DRC) in January after 816 from China, Pakistan, India and Bangladesh nationality peacekeepers and 690 local residents Parasites questionnaire investigation of their work and the mosquito and anti-malaria and to conduct analysis of parasite infection. The local hospital and peacekeeping two hospital laboratory reports Plasmodium infection methods were compared. Results: 1 target population Plasmodium infection rate was 53.0% (798/1506). Where peacekeepers infection rate was 29.7% (242/816), 80.6% of local residents infection (556/690). (2) the target population infected with Plasmodium falciparum, P. vivax, P. malariae and P. ovale constituent ratio were 90.7%, 0.8%, 8.5% and 0%. 3 different ages malaria infection rates among local residents were 0-10 years old group, 95.0% (192/202); 11-20 age group 87.6% (106/121); 21-30 age group 76.6% (82/107 ); 31-40 age group 71.0% (71/100); 41-50 age group 66.0% (64/97); 51-60 age group 62.3% (33/53); 61 years of age group 80% (8 / 10). 4 Chinese nationals peacekeepers parasite prevalence was significantly lower than from Pakistani, Indian and Bangladeshi nationals three peacekeepers (P lt; 0.05); Pakistani peacekeepers infection rate was significantly lower than Indian and Bangladeshi peacekeepers (P lt; 0.05); Indian staff infection rate was significantly lower than the Bangladeshi officer (P lt; 0.05). 5 peacekeepers and personnel engaged in medical work parasite prevalence was significantly lower than in other nature staff (P ??lt; 0.05). 6 using Chinese peacekeepers and two hospitals method Plasmodium inspection report high number of white blood cells infected with Plasmodium falciparum samples with high accuracy results reported in Congo (gold) local hospital reporting methods 1 (P lt; 0.05). 7 different sample volume and push the film angle of the Congo (gold) local hospital inspection reports Plasmodium Method 2 reported results were significantly affected (P lt; 0.05). Large drops of blood, pushing the launch angle is large slice of the blood smear report results seriously high. Meanwhile 20μl, 30 ° angle with 20μl, 45 ° angle of two kinds of methods, no significant difference (P gt; 0.05). Conclusions: 1. Congo (gold) local residents infected with the malaria parasite prevalence is higher, and mainly to malaria infection groups are primarily young people and children. This is the natural, health and economic conditions are related. (2) is caused by Plasmodium falciparum Congo (gold) peacekeepers major parasite infection, the different nature of the work staff there are differences between the infection rate should be based on the nature of work undertaken preventive measures; need to strengthen peacekeeping personnel before leaving the training of anti-mosquito and anti-malaria and healthy before returning. 3 Chinese nationality peacekeepers to take anti-malaria mosquito system specifications measures to make its parasite prevalence lower than Pakistan, India and Bangladesh nationals peacekeepers. 4 Chinese peacekeepers and two hospitals had Plasmodium infection reporting methods can effectively improve the detection rate, detailed and specific reflection of the real situation of the patient's body parasites, as well as changes in the number of white blood cells to prevent blood smears made errors caused by other factors, correct and effective clinical, better than the Congo (gold) local hospital reporting methods.
