目的研究枝江市1979～2008年疟疾流行特征,评价其防治效果,为今后进一步巩固灭疟成果提供理论依据和改进方案。方法采用描述流行病学方法。结果30年共观察人年数15 069 884,发生疟疾1 230例,发病率(IR)为0.82/万人年;近3年无感染病例,1990年后IFAT及居民带虫率调查结果阴性;灭疟后期现症病人根治率及休止期根治率为100%。结论枝江市疟疾发病具有典型的灭疟后期的流行特征;抗疟措施符合实际,效果明显;现症病人根治、休止期根治及病家防蚊灭蚊是主要关键技术措施;流动人口增加和传染源输入是影响流行趋势的主要因素。
Objective To study the epidemiological characteristics of malaria in Zhijiang City from 1979 to 2008 and evaluate its control effect so as to provide theoretical basis and improvement plan for further consolidating the achievements of malaria elimination in the future. Methods used to describe epidemiological methods.
