辽宁省1999～2000年疑似麻疹病例流行病学分析

Epidemiological Analysis of Suspected Measles Cases in Liaoning Province in 1999 and 2000

辽宁省自 1999年建立麻疹监测系统以来 ,监测系统的敏感性不断提高 ,1999、2 0 0 0年麻疹监测系统报告的麻疹疑似病例数分别较法定传染病报告系统多 3 3%和 16 7%,报告县数也由 1999年的 39%上升到 2 0 0 0年的5 4%。全省麻疹以局部爆发为主 ,存在明显的冬春季流行高峰 ,学龄儿童所占比例由 1999年的 40 2 %上升到 2 0 0 0年的 5 4 4 %,“零”剂次和 1剂次免疫的比例由 1999年的 6 4 %和 2 2 8%上升到 2 0 0 0年的 12 4 %和 39 3%。可见今后应以控制麻疹爆发为主 ,控制策略的重点是提高麻疹疫苗基础免疫和复种接种率 ,消除免疫空白。

The sensitivity of measles surveillance system has been improving continuously since its establishment in Liaoning Province in 1999.The suspected measles cases reported in 1999 and 2000 were 3.3% and 16.7% respectively, higher than that reported by National Notifiable Disease Reporting System.The counties that delivered reports of suspected measles cases increased from 39% in 1999 to 54% in 2000. Measles occurred in an outbreak form with a prevalent peak in winter and spring.School-age children infected accounted for 40.2% in 1999 and 54.4% in 2000. The zero-dose and 1-dose immunized children were 6.4% and 22.8% in 1999 and raised to 12.4% and 39.3% in 2000 respectively. For control of measles outbreak,the strategy adopted is to raise the coverage rate of basic immunization,the revaccination rate of measles vaccine, and make efforts to eliminate the immunization blank space.
