Abstract

To review and investigate the malaria control history of Wuzhou City, Guangxi Zhuang Autonomous Region from 1950 to 2015, so as to provide the evidence for future malaria control and surveillance. The data of malaria control in Wuzhou City from 1950 to 2015 were collected and analyzed. In 1950 decade, the malaria incidence in Wuzhou City was 1 435.55/100 000, higher than the average level in Guangxi, and the mortality of malaria was 0.95/100 000. The malaria incidence of local residents was reduced to 3.61/100 000 in 1979 and no local malaria case was found since. The imported malaria cases were found in Wuzhou City since 1980, and were more than local cases since 1981. In recent five years, 87.50% (7/8) of imported malaria cases were from south-east Asia. Wuzhou City has reached the national criterion of malaria elimination, but the imported malaria is the recent threat. The surveillance and control work of malaria should be strengthened.
