[Epidemic trend of malaria in Suzhou City, Jiangsu Province, China from 2007 to 2012].

Objective: To understand the epidemic trend of malaria in Suzhou City, Jiangsu Province, so as to provide the evidence 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 residents with vivax malaria, and the annual incidence rate was 0.07/10(5). Among the floating population, there were 290 malaria cases (91.19%) and the annual incidence rate was 0.77/10(5), 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.
