Abstract:
ObjectiveTo analyze the incidence and epidemic characteristics of imported malaria cases after malaria were eliminated in Liuzhou city, provide scientific basis for consolidating the results of malaria control and prevention,and formulating the strategies of malaria surveillance. MethodsThe study was carried out on all the date of clinic and epidemiology collected from the imported malaria cases after malaria was eliminated. ResultsThe major population suffering from malaria was the floating population, especially those from the areas with high incidence rate, including Africa, with the incidence being higher in the population back from overseas than in the floating population from other domestic areas. The plasmodium vivax was found to be the most common of malaria species. The malaria incidence peaked from May to November each year, majority of which was male young adults. ConclusionConsidering the epidemic characteristics of imported cases, we should reinforce the management and surveillance of floating population, especially those who were from the areas with high malaria incidence rate, when establishing the surveillance strategies and plans for malaria control after it was eliminated locally.
