Abstract: Objective To understand the epidemic trend of malaria in Suzhou City，Jiangsu Province，so as to provide the ev? idence for developing the strategies of malaria elimination. Methods The malaria information was collected from 2007 to 2012 through the reporting system of Suzhou epidemic information network and parasitic network system，and the results were analyzed statistically. Results From 2007 to 2012，there were 318 malaria cases reported. Among them，28 cases（8.81%）were local resi? dents with vivax malaria，and the annual incidence rate was 0.07/105 . Among the floating population，there were 290 malaria cases （91.19%）and the annual incidence rate was 0.77/105 ，including 233 vivax malaria cases，20 falciparum malaria cases，1 ovale malaria case，and 1 mixed infection case. The malaria incidence rate of local residents dropped year by year in the past 6 years while that of floating populations increased. During the period of the later 3 years，no local malaria case was found. Conclusion The malaria has been eliminated among the local residents while the malaria cases from floating populations increased. Therefore， we should strengthen the cross?regional joint malaria control and prevention， and the malaria management of entry?exit persons.
