To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2015, so as to provide the evidence for malaria elimination.

All the malaria cases were imported, and 5 cases (1.23%) were from Southeast Asia and 400 (98.77%) were from 25 African countries or regions. The imported malaria cases were reported in 13 cities across Jiangsu Province, where Taizhou, Lianyungang, Nantong, Huaian and Yangzhou cities accounted for 68.64% of all the cases in the province. Jiangsu Institute of Parasitic Diseases (JIPD) reference lab checked all the cases and classified 299 falciparum malaria cases, 13 vivax malaria cases, 18 quartan malaria cases, 71 ovale malaria cases, and 4 mixed Plasmodium infection cases.
