Objective To understand the malaria prevalence in different provinces though analyzing the results of the malaria indirect fluorescent antibody test （IFAT） of college freshmen in Guilin City from 2010 to 2012, so as to provide the evidence for formulating the management policies of post-malaria elimination. Methods The peripheral blood samples of 101 721 college freshmen who came from different provinces of China were collected and tested with IFAT in Guilin City from 2010 to 2012, and the re.suits were analyzed statistically. Results Among the 101 721 students aged between 16 and 22 years, the male to female ratio was 1.36 ： 1, and the IFAT positive rates were 4.09/10 000 and 4.13/10 000 in the men and women, respectively. The positive rate was 0.82/10 000 in the students born from Guilin City, and the rates were 19.92/10 000, 12.26/10 000, 9.04/10 000, 8.24/10 000, 8.01/10 000, and 3.49/ 10 000 in the students born from Hainan, Guizhou, Yunnan, Sichuan, Henan, and Hubei provinces, respectively. The IFAT positive rate was 1.12/10 000 in the students born from the other provinces. Conclusions The IFAT positive rate in the students born from Guilin City is significantly lower than that in the students born from the malaria endemic areas. Therefore, we should strengthen the management of floating population to prevent imported malaria cases as the priorities in the malaria prevention and control in Guilin City.
