Epidemiological Analysis on Acute Flaccid Paralysis Surveillance System in Liaoning Province from 1993 to 1999

目的 为了解辽宁省急性弛缓性麻痹 (简称AFP)病例的流行病学特征及监测系统指标的完成情况 ,对 1993年以来的AFP病例及监测状况进行分析。方法 用流行病学方法进行比较分析。结果 AFP病例的敏感性逐年提高 ,自 1995年以来已连续 5年稳定在 1/ 10万以上 ;报告AFP病例的县区占全省县区的比例自 1993年的 34%逐年增加到 1999的 6 2 % ;近年来AFP病例已无明显的年历分布和季节高峰 ;零剂次免疫的AFP病例逐年减少 ,1999年仅占1 1% ;双份合格便标本采集率自 1996年以来一直稳定在 80 %以上。结论 自 1996年以来 ,监测系统的各项质量控制指标均达到WHO和卫生部的要求。但全省仍存在监测薄弱地区和环节 ,今后须加强对高危地区的监测工作 ,以提高监测系统识别输入野病毒的能力。
