Objective To analyse the effect of malaria control, epidemiologic trend and characteristics in Guangxi in 2001, and provide a basis for malaria prevention and surveillance. Methods Analyze and study the materials from malaria surveillance, investigation throughout Guangxi in 2001. Result Malaria incidence and parasite rate in residents decreased from 21.74% to 16.67% respectively. 91.49% of the local cases were distributed over mountain counties, and 86.02% of the focus villages contained only one case. The floating population with imported malaria cases account for 87.89% of the total cases, in which 84.79% engaged in fieldwork. Conclusion The majority of Guangxi is low with malaria epidemic. However in some areas, malaria transmisson has not been completely blocked. The floating population and the areas with An.minimus and An.anthropophagus are keys of malaria surveillance at present.
