2004—2013年睢宁县疟疾疫情分析

Analysis of epidemic situation of malaria in Suining County,2004—2013

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。

Objective To understand the characteristics of epidemic situation of malaria in Suining County from 2004 to 2013, so as to provide the evidence for improving malaria control measures. Methods The information of malaria cases frcm 2004 to 2013 was collected and analyzed statistically to understand the epidmlic trend of malaria and the prevention and control measures. Results Frown 2004 to 2013, 298 malaria cases were reported, and all were sporadic. The annual incidence was 2.33/10 thousand. There were 292 cases of vivax malaria, 6 cases of faldparum malaria. 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）. Conclusions In Suining County, vivax malaria has been effectivdy controlled, but overseas imported falciparum malaria is increasing every year. Therefore, the initiative malaria case detective work should be strengthened and the health education of malaria prevention and control in overseas workers also should be enhanced.
