目的分析睢宁县2004—2013年疟疾疫情特征,为睢宁县防治疟疾措施提供科学依据。方法收集2004—2013年间睢宁县疟疾病例信息,采用回顾性方法分析病例特征,分析疟疾的流行趋势和防治措施。结果 2004—2013年睢宁县共报告疟疾病例298例,均为散在病例,年发病率2.33/10万。间日疟292例,恶性疟6例。2011年无疟疾病例报告,且2011年之后病例均为输入性恶性疟病例。间日疟有明显的时间分布高峰（χ2=18.47,P〈0.05）,而恶性疟无明显的时间分布高峰。报告的病例男女比例为1.4∶1,年龄最大的94岁,最小的4个月,中老年农民发病最多。地区差异有统计学意义（χ2=375.85,P〈0.01）。结论睢宁县间日疟病例得到有效的控制,但是境外输入性恶性疟病例逐年增加。应加强周围人群主动病例侦查工作,同时要加大对境外务工人员的疟疾防治知识宣传工作。

In 2011, no malaria cases were reported, and after 2011, all the malaria cases reported were imported of falciparum malaria. There was an obvious peak time of distribution of vivax malaria （X2 = 18.47, P 〈 0.05）, whereas no significant peak time of falciparum malaria distribution. The male to female ratio was 1.4： 1. The oldest patient was 94 years and the youngest was 4 months. The highest incidence was among older farmers. There was a significant regional difference （？（2 = 375.85, P 〈 0.01）.
