摘　　要：目的了解桂林市大中专新生疟疾血清抗体水平,为本市疟疾防治提供参考。方法对1999—2009年每年本市各大学、中专和专业技术学校入校新生收集血清样品,采用疟疾间接荧光抗体试验(IFAT)的方法进行检测,并用Excel软件作资料统计处理。结果共检查大中专新生257 055名,发现疟疾IFAT阳性者共307名,人群年平均阳性率为11.94/万,阳性平均滴度(阳性GMRT)为54.23,总平均滴度(总GMRT)为20.03。大学生中阳性者为178名,本省籍学生占42.70%,外省籍学生57.30%。人群年平均阳性率为8.64/万。中专技校生中阳性者为129名,本省籍学生占84.50%,外省籍学生15.50%。中专技校学生人群年平均阳性率为25.25/万。10年期间疟疾IFAT阳性者数量呈现逐年下降的趋势,从1999年54.68/万下降到2009年的3.04/万。结论该市大中专新生中长期存在疟疾感染者,尽管本世纪以来被感染者人数呈现逐年减少的趋势,但其监测仍需继续。Objective To understand the serum malaria-antibody levels in new students of universities and technical secondary schools in Guilin City, so as to provide the evidence for improving malaria control strategy. Methods The serum .samples were collected and detected by using malaria indirect fluorescent antibody test （IFAT） in new students of universities and technical secondary schools in Guilin City, and the results were analyzed statistically with Excel software. Results A total of 257 055 samples were detected including 307 IFAT positive cases of malaria, the average positive rate was 11.94 /10 000, and the positive mean titer （positive GMRT） was 54.23, with a mean titer （total GMRT） of 20.03. Totally 178 college students were positive, and among them, there were 42.70% of local students and 57.30% of students from other provinces. The average positive rate was 8.64 /10 000. Totally 129 technical secondary school students were positive, and among them, there were 84.50% of local students and 15.50% of students from other provinces. The average positive rate was 25.25/10 000. The IFAT positive rates declined year by year over the past ten years, from 54.68/10,000 in 1999 to 3.04/10 000 in 2009. Conclusions There are still malaria infected persons in the new students of universities and technical secondary schools in Guilin City although the number of infected people decreases year by year in this century. So the monitoring still needs to continue.
