目的 目的 掌握江苏省2012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 方法 法 对2012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 结果 2012年江苏省共报告疟疾198例， 较2011年的374例下降了47.06%， 发病率为0.026/万， 均为国外输入性病例。全省13个市均有疟疾病例报告， 其中扬州、 南通、 南京、 泰州、 徐州和淮安报告的病例占全省的71.72% （142/198）。省疟疾诊断参比实验室对196份样本进行复核， 确定恶性疟164例、 间日疟6例、 卵形疟22例、 三日疟1例、 混合感染3例。结论 结论 2012年江苏省首次实现无本地感染疟疾病例， 境外输入性疟疾病例数虽明显下降， 但病例分布范围进一步扩大， 且感染虫种呈多样性。境外输入性疟疾仍是本省疟疾防控工作的重点。

Epidemiological analysis of malaria prevalence in Jiangsu Province in 2012

Objective To understand the malaria epidemic situation and characteristics in Jiangsu Province in 2012,so as to provide the evidence for formulating and adjusting effective malaria elimination strategies and measures. Methods The reported malaria cases from the Internet Reporting System and the epidemiological data of malaria in Jiangsu Province were collected and analyzed. Results A total of 198 malaria cases were reported in Jiangsu Province in 2012 with the incidence of 0.026/10 000, which decreased by 47.06%compared with that in 2011（374 cases）. A total of 198 malaria cases were reported from 13 prefec-tures of Jiangsu and the cases were mainly distributed in Yangzhou（34 cases）,Nantong（31 cases）,Nanjing（22 cases）,Tai-zhou（21 cases）,Xuzhou（17 cases）and Huaian（17 cases）,which accounted for 71.72%（142/198）among the total cases of the province. There were no local malaria cases reported from Jiangsu in 2012,and the imported malaria cases from other countries de-creased by 45.15%compared with that in 2011. Conclusions For the first time,there are no local malaria cases reported from Ji-angsu in 2012. However,the imported case distribution is further expanded and the infected plasmodium parasites are more di-verse. Imported malaria from other countries remains the key for malaria control in Jiangsu Province.
