Objective: To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2017, so as to provide the evidence for formulating the targeted strategy of malaria elimination.
Methods: The data of malaria cases in Jiangsu Province in 2016 were collected from China's Routine Diseases Surveillance Information System (CRDSIS).
Results: Totally, 239 imported malaria cases were reported in Jiangsu Province in 2017, and the cases decreased by 22.40% compared to 308 cases in 2015. Except 2 malaria case caused by blood transfusion, the rest patients were all imported. Among them, there were 163 falciparum malaria cases, 21 vivax malaria cases, 11 quartan malaria cases, 43 ovale malaria cases, and 1 mixed infection case (Plasmodium falciparum and P. ovale). The numbers of imported cases of Nantong (39 cases, 16.32%), Suzhou (26 cases, 10.88%), Taizhou (25 cases, 10.46%), Huai'an (24 cases, 10.04%), and Lianyungang (22 cases, 9.21%) ranked in the top 5 cities across Jiangsu Province, the malaria cases in the five cities accounted for 56.90% (136/239). The infection source areas of the imported malaria cases included Africa (225 cases), Asia (8 cases), Oceania (2 cases), and South America (2 cases).
Conclusions: Jiangsu Province has no local malaria cases for 6 consecutive years. Despite the imported cases in 2017 decreased some-what compared to that in 2016, it is still necessary to strengthen the surveillance of imported malaria cases and improve malaria diagnosis and treatment in the whole province.
