目的对广西桂林市2010~2012年大中专新生进行疟疾间接荧光抗体试验(IFAT),了解来自不同省份学生的疟疾感染情况,为制定消除疟疾后期管理政策提供依据。方法对大中专新生采末梢血进行血清学检测,并分析结果。结果 101 721名新生接受疟疾血清学检测,新生年龄在16~22岁,男女比例1.36∶1,男女阳性率分别为4.09/万和4.18/万;桂林市大学新生IFAT阳性率0.82/万,海南、贵州、云南、四川、河南、湖北等省新生的阳性率分别为19.92/万、12.26/万、9.04/万、8.24/万、8.01/万、3.49/万,其他省份新生阳性率为1.12/万。结论桂林市出生的学生IFAT阳性率明显低于一类流行地区,做好流动人口管理,防止输入性病例是桂林市疟疾防控的工作重点。
Objective To study the indirect immunofluorescence antibody test (IFAT) of malaria in freshmen in Guilin from 2010 to 2012 to understand the malaria infection among students from different provinces and provide the basis for formulating the post-malaria management policy. Methods Serological tests were carried out on the peripheral blood collected from freshmen in colleges and universities and the results were analyzed. Results A total of 101 721 new malaria seropositive children aged 16 to 22 years old were enrolled in this study. The male to female ratio was 1.36:1. The positive rates of male and female were 4.09 / million and 4.18 / million respectively. The positive rate of IFAT in Guilin freshmen was 0.82 / The positive rates of newborn students in Guizhou, Yunnan, Sichuan, Henan and Hubei provinces were 19.92 / million, 12.26 / 10,000, 9.04 / million, 8.24 / million, 8.01 / million and 3.49 / million respectively. The positive rates of newborn students in other provinces were 1.12 / Million Conclusion The positive rate of IFAT among students born in Guilin is obviously lower than that of one endemic area. It is the focus of prevention and control of malaria in Guilin that migrants should be well managed to prevent imported cases.
