目的了解和分析不同流行阶段和时期抗疟策略和措施对降低疟疾发病率的效果。方法回顾性收集、整理襄阳市襄州区1951-2013年疟疾防治资料,采用描述流行病学方法进行分析。结果襄州区63年间共发生疟疾病例917 068例,年均发病率为143.91/万。疟疾流行阶段年均发病率为352.55/万;疟疾控制阶段年均发病率为11.81/万;疟疾消除阶段(期)年均发病率为0.09/万。不同阶段年均发病率比较,差异有统计学意义(χ2=31 393984.77,P<0.01)。结论不同流行阶段流行因素及防治策略和措施不同,对降低疟疾发病率的效果不完全相同。
Objective To understand and analyze the effect of malaria strategies and measures in different phases and periods on reducing the incidence of malaria. Methods The retrospectively collected and compiled malaria control data from 1951 to 2013 in Xiangzhou District, Xiangyang City were analyzed by descriptive epidemiological method. Results A total of 917 068 malaria cases occurred in Xiangzhou District in 63 years, with an average annual incidence of 143.91 / million. The average annual incidence of malaria in the epidemic phase was 352.55 / million. The annual average incidence of malaria in the control phase was 11.81 / million. The annual average incidence of malaria was 0.09 / million. The average annual incidence of different stages of comparison, the difference was statistically significant (χ2 = 31393984.77, P <0.01). Conclusions The epidemic factors and control strategies and measures in different epidemic stages are different, and their effects on reducing the incidence of malaria are not exactly the same.
