摘要
[目的]了解杭州市1952～2005年以来流行性乙型脑炎(以下简称乙脑)的发病情况,为分析杭州市乙脑发病特点及流行规律,进一步完善免疫策略,有效控制乙脑发病提供科学依据。[方法]利用传染病报告系统报告数据,分析杭州市乙脑流行病学特征。[结果]杭州市乙脑发病率从20世纪70年代开始呈大幅度下降趋势,到20世纪90年代已降到﹤1/10万,2000年以后发病率降到﹤0.2/10万。县区发病高于市区,发病呈明显的季节性,主要集中在6、7、8、9 4个月,占总发病人数的98.53%,93.35%病例为﹤15岁儿童。[结论]降低乙脑的发病率应降低乙脑疫苗的初免年龄,提高接种率,采取灭蚊、防蚊为主的综合性预防措施。
