Objective: To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2016, so as to provide the evidence for formulating and adjusting the strategy and measures for malaria elimination.
Methods: The data of malaria cases in Jiangsu Province in 2016 were collected from China's Routine Diseases Surveillance Information System (CRD-SIS) and analyzed statistically.
Results: Totally, 308 malaria cases were reported in Jiangsu Province in 2016, and the cases decreased by 23.95% compared to 405 malaria cases in 2015. Except for 1 malaria case that was caused by blood transfusion, the rest patients were all imported. Among the 308 cases, 237 were infected with Plasmodium falciparum, 11 were infected with P. vivax, 8 were infected with P. malariae, 51 were infected with P. ovale, and 1 was mixed infection. Among all the cities in Jiangsu Province, the numbers of imported cases of Nantong (53 cases), Huai'an (41 cases), Taizhou (40 cases), Lianyungang (36 cases) and Yangzhou (29 cases) ranked in the top 5, and the total malaria cases in the five cities accounted for 64.61%.
Conclusions: There were no local malaria cases in Jiangsu Province for 5 consecutive years up to 2016. Although the imported cases decreased slightly compared to those in 2015, we still should strengthen the surveillance of imported malaria cases as well as improve malaria diagnosis and treatment abilities for related personnel at all levels of medical institutions. Also we should focus on the Plasmodium check, focus survey and disposal to realize the aim of malaria elimination in Jiangsu Province in time.
［摘要］目的 掌握江苏省2016年疟疾疫情及流行特征, 为制订和调整适合本省的消除疟疾策略和措施提供依据。 方法 对2016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 2016年江苏省共报告疟 疾308例, 较2015年的405例下降了23.95%。308例疟疾病例中, 恶性疟237例、间日疟11例、三日疟8例、卵形疟51例、恶性疟与三日疟混合感染1例; 除1例为输血感染外, 其余均为境外输入病例。病例数居前5位的设区市分别为：南通市 (53例) 、淮安市 (41例) 、泰州市 (40例) 、连云港市 (36例) 、扬州市 (29例),5市病例数共占全省报告病例数的64.61% (199/308) 。 结论 截至2016年, 江苏省连续五年实现无本地感染疟疾病例; 境外输入性疟疾病例虽较2015年有所下 降, 但仍是本省疟疾防控工作的重点。应加强对出国务工人员的疟防知识宣传, 提高其自我防护意识, 并提高各级医疗 机构相关人员对疟疾的诊断和治疗能力, 提升疾控机构专业人员病原复核、疫点调查和处置能力, 确保如期实现消除疟 疾目标。.
