山东省 1993～ 1998年 5次 10轮NID实施效果比较分析 ,结果显示 :随着NID的继续 ,服苗人数不断增多 ,脱漏人数不断减少 ,每一次NID都是对上一次的补充和加强。大年龄组儿童服苗较好 ,0岁组相对较差 ,是历次NID的薄弱环节。NID实施的质量和效果好于常规免疫 ,接种资料的可靠性和准确性均较好 ,持续NID的效果是可取的 ,建议常规免疫和NID相结合仍应作为今后消灭脊灰首选策略。
The results of five rounds of NID implementation in five rounds in Shandong Province from 1993 to 1998 showed that with the continued NID, the number of service-taking mites increased continuously and the number of missed patients kept decreasing. Each NID was supplemented and strengthened last time. Children in older age groups better clothes, 0-year-old group is relatively poor, is the weakness of the previous NID. The quality and effect of NID implementation is better than that of routine immunization. The reliability and accuracy of vaccination data are good. It is advisable to continue the effect of NID. It is suggested that the combination of routine immunization and NID should still be the first strategy of eliminating polio.
