Results From 2008 to 2014，a total of 305 malaria cases were reported in Nantong City，with an an? nual average incidence of 0.57/100 000. Among all the cases，26（8.52%）were local tertian malaria cases and 279（91.48%） were imported cases；276 cases（90.49%）were male and most of them were young adults，and those aged in 20-59 accounted for 91.48%（279/305）. There were cases reported in each month，with no obvious seasonality. The imported cases were mainly distributed in Hai’an County（80 cases），Haimen City（71 cases）and Tongzhou District（41 cases），and the total percentage of them was 68.82% among all the imported malaria cases in Nantong City. There were no local malaria cases reported in Nan? tong City since 2011. Qidong City，Rudong County，Chongchuan District，Development Zone and Gangzha District have reached the criteria of malaria elimination in Jiangsu Province.
