Objective To analyze the surveillance of malaria in mobile population in Guanyang County of Guangxi from 2001 to 2014 and provide basis for malaria prevention and control measures. Methods The data of malaria infection source surveillance and serological surveillance in Guanyang County from 2001 to 2014 were collected and analyzed statistically. Results A total of 47 imported cases of imported malaria were reported among floating population in Guanyang County from 2001 to 2014, with an average annual incidence of 0.12 / million. Among them, 30 were Plasmodium falciparum and 17 were Plasmodium falciparum. No deaths and second-generation cases occurred. The number of cases reported in 2002 was the largest, 21 cases, with a prevalence of 2.41%. There was no reported case of imported malaria since 2006. Between 2001 and 2014, a total of 2 522 blood samples were collected, of which 47 were positive for Plasmodium, the average positive rate was 1.86%. The sources of imported cases of infection were mainly in Yunnan, Hainan, Guizhou and Guangdong Provinces. After 2003, the sources of imported cases were changed to foreign countries in Myanmar and Vietnam. The cases were mainly planted with crops, mining and logging Second.
