【摘要】 对山东省１９５１～１９９４年麻疹流行特征分期进行了分析，结果表明：实施麻疹疫苗接种和儿童计划免疫后，随着麻疹疫苗使用量的增加，免疫程序的完善及免疫接种率的提高，麻疹年平均报告发病率由麻疹疫苗使用前的６５５．０５／１０万，分别降至３０５．９２／１０万和１７．４５／１０万，削平了麻疹流行的持续高峰，打破了自然流行周期，发病年龄较前有所后移，发病区域趋于缩小。目前，山东省麻疹发病已处于疫苗时代的“相对稳定期”，要达到基本消除麻疹的目标，尚需进一步提高和保持高水平的免疫接种率，加强疫情报告与监测，适时选择高危地区和人群开展强化免疫，做好疫情暴发控制及实验室检测工作。更多还原

【Abstract】 he survey on measles epidemiology in 1951-1994 showed that the mean morbidity ofmeasles before using the vaccine was 655.05/100,000,but sharply decreased to 17.45/100,000since the measles vaccination was carreid out from 1967. Further more,the persistent epidemicpeak was cut down,the natural epidemic period was broken,the age of morbidity moved to the el-der and the epidemic area reduced. For the aim of eliminating measles,a high coverage of vaccina-tion,surveillance of measlescases,supplemental immunization in high risk areas and populations,and the laboratory assays are needed.更多还原
