Abstract: 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 somewhat 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.

摘要: 目的 掌握2017年江苏省疟疾疫情及流行特征,为制订和调整适合本省的消除疟疾后监测策略和措施提供依据。方法 对2017年全省网络报告疟疾疫情和专报系统的流行病学调查资料进行统计分析。 结果 2017年江苏省共报告疟疾239例,较2016年的308例下降22.40%。239例疟疾病例除2例为输血感染外,其余237例均为境外感染的输入性病例。239例疟疾病例中,恶性疟163例、间日疟21例、三日疟11例、卵形疟43例、恶性疟原虫与卵形疟原虫混合感染1例。2017年全省13个设区市均有疟疾病例报告,其中居前5位的为南通市(39例,16.32%)、苏州市(26例,10.88%)、泰州市(25例,10.46%)、淮安市(24例,10.04%)和连云港市(22例,9.21%),5市合计报告的疟疾病例数占全省报告的疟疾病例总数的56.90%(136/239)。输入性疟疾报告病例的主要感染来源地为非洲(225例)、亚洲(8例)、大洋洲(2例)、南美洲(2例),其中大洋洲和南美洲为新出现的感染来源地区。结论 江苏省连续6年无本地感染疟疾病例。2017年境外输入性疟疾病例虽较2016年有所下降,但仍是全省疟疾防控工作的重点。
