Abstract: Objective To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2012，so as to provide the evidence for formulating and adjusting effective malaria elimination strategies and measures. Methods The reported malaria cases from the Internet Reporting System and the epidemiological data of malaria in Jiangsu Province were collected and analyzed. Results A total of 198 malaria cases were reported in Jiangsu Province in 2012 with the incidence of 0.026 /10 000， which decreased by 47.06% compared with that in 2011 （374 cases） . A total of 198 malaria cases were reported from 13 prefec? tures of Jiangsu and the cases were mainly distributed in Yangzhou（34 cases），Nantong（31 cases），Nanjing（22 cases），Tai? zhou（21 cases），Xuzhou（17 cases）and Huaian（17 cases）， which accounted for 71.72%（142/198）among the total cases of the province. There were no local malaria cases reported from Jiangsu in 2012，and the imported malaria cases from other countries de? creased by 45.15% compared with that in 2011. Conclusions For the first time，there are no local malaria cases reported from Ji? angsu in 2012. However，the imported case distribution is further expanded and the infected plasmodium parasites are more di? verse. Imported malaria from other countries remains the key for malaria control in Jiangsu Province.
