1983-2010年南通市流行性乙型脑炎监测结果分析

Analysis on monitoring results of epidemic encephalitis B in Nantong from 1983 to 2010

目的分析南通市流行性乙型脑炎(乙脑)综合监测资料,为制定防控措施提供依据。方法采用回顾性调查的方法对1983-2010年乙脑病例资料进行分析。结果 1980年始南通市广泛使用乙脑疫苗预防接种,1983年发病率为3.72/10万,以后发病率呈周期波动性下降,至2000年后发病数呈低发病水平的波动。2000-2010年间年发病率均低于0.08/10万。乙脑发病季节性明显,集中发生在6～9月。结论南通市乙脑发病已控制在较低水平,为避免造成流行性乙型脑炎的传播和流行,须进一步完善预防接种、控制媒介传播、健康教育和加强监测等综合性防治措施。

Objective To analyze comprehensive monitoring data of epidemic encephalitis B in Nantong, so as to provide basis for the development of prevention and control. Methods The material of encephalitis B cases from 1983 to 2010 were analyzed by retrospective method. Results We have widely used JE vaccine in Nan- tong since 1980. The incidence of JE was 3.72/100 000. The incidence showed a cycle fluctuation decline trend, and since 2000 the incidence was at a low level fluctuation. The incidence of JE was less than 0. 08/ 100 000 from 2000 to 2010. The incidence of JE showed obvious seasonal rules and centralized from June to September. Conclusions The JE incidence of Nantong was controlled to a relatively low level. In order to a- void the transmission and prevalence of JE, we should take comprehensive measures by further perfecting vac- cination and controlling the media, strengthening monitoring and health education.
