目的评价学龄前流动儿童强化查漏补种策略实施效果。方法采用现场流行病学调查方法,对2007年学龄前流动儿童强化查漏补种实施进行质量评估。结果在强化查漏补种实施内容扩展,学龄前流动儿童人数、聚集乡(镇、街,下同)数大幅度增加的情况下,全市强化查漏补种质量评估后的返工乡数减少。2007年学龄前流动儿童强化查漏补种后建证率达100%,建卡率达99.6%,口服脊髓灰质炎减毒活疫苗、百日咳-白喉-破伤风联合疫苗、麻疹减毒活疫苗、乙型肝炎疫苗的基础免疫(初种)接种率达96.7%,脑膜炎球菌多糖疫苗接种率达94.7%。结论在全市学龄前流动儿童总数、强化查漏补种疫苗种类增加的情况下,2007年学龄前流动儿童强化查漏补种达到了评价指标。
Objective To evaluate the implementation effect of enhanced leak detection and seeding strategy in preschool children. Methods A field epidemiological survey method was used to assess the quality of enhanced leak detection and replanting in preschool children in 2007. Results In the case of strengthening the content of leak detection and replanting implementation, the number of preschool migrant children and the number of gathering towns (towns, streets and the same below), the number of reworked towns in the city after strengthening quality assessment of leak detection and replanting decreased. In 2007, children with pre-school-age children underwent leak-finding and post-vaccination construction with an established rate of 100% and a card-building rate of 99.6%. The live attenuated oral polio vaccine, the combined pertussis-diphtheria-tetanus vaccine, live attenuated measles vaccine, Hepatitis B vaccine basic immunization (primary) vaccination rate of 96.7%, meningococcal polysaccharide vaccination rate of 94.7%. Conclusions With the increase of the total number of preschool children in the city and the increase in the number of vaccination and vaccination vaccines, the evaluation index was reached in 2007 when the children of pre-school-age migrant workers went through intensive leak detection and replantation.
