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 analyze the epidemic characteristics of malaria in Suining County from 2004 to 2013 and provide a scientific basis for the prevention and control of malaria in Suining County. Methods The information of malaria cases in Suining County was collected from 2004 to 2013. The retrospective methods were used to analyze the characteristics of malaria cases. The epidemic trend of malaria and the prevention and cure measures were analyzed. Results A total of 298 malaria cases were reported in Suining County from 2004 to 2013, all of which were scattered cases with annual incidence of 2.33 / lakh. 292 cases of vivax malaria and 6 cases of falciparum malaria. No cases of malaria were reported in 2011, and cases of imported malaria were imported after 2011. Volatile Plasmodium had a significant peak in time distribution (χ2 = 18.47, P <0.05), but no significant peak in time distribution of P. falciparum. Reported cases of male to female ratio of 1.4: 1, the oldest 94 years, the youngest 4 months, the most incidence of middle-aged peasant farmers. Regional differences were statistically significant (χ2 = 375.85, P <0.01). Conclusion The Sumatra malaria cases in Suining County are effectively controlled, but the cases of imported malaria cases abroad are increasing year by year. We should step up the investigation of the active cases among the people in the surrounding areas and at the same time, intensify the propaganda work on malaria prevention and control among overseas workers.
