目的了解浙江省温州市急性弛缓性麻痹(AFP)病例的流行特征,进一步提高AFP监测系统的敏感性、及时性、完整性,为制定保证无脊髓灰质炎状态的措施提供科学依据。方法对温州市2004-2009年AFP病例资料进行分析。结果 2004-2009年温州市共报告AFP病例100例,男女病例性别比为2.13∶1。发病率除2004年为0.5/10万外,其余年份在1/10万～1.5/10万之间,均保持在1/10万及以上。14 d内双份合格粪便标本采集率在95.2%～100%之间。除2008年随访率为76.5%,其余年份在87.5%～100%之间。此外AFP等监测指标均达到80%的要求。分离出4例脊灰病毒,均为疫苗株。结论温州市AFP各项监测指标明显提高,AFP监测工作日趋完善,因此做好脊髓灰质炎疫苗的常规免疫和强化免疫,提高AFP病例报告的敏感性和及时率,加强AFP管理的督导工作是继续保持无脊灰状态的重要保证。
Objective To understand the epidemiological characteristics of acute flaccid paralysis (AFP) in Wenzhou City, Zhejiang Province and further improve the sensitivity, timeliness and completeness of AFP monitoring system and provide a scientific basis for the development of measures to ensure polio-free status. Methods AFP cases from 2004 to 2009 in Wenzhou City were analyzed. Results A total of 100 AFP cases were reported in Wenzhou from 2004 to 2009, with a sex ratio of 2.13:1. In addition to the incidence of 0.5 / 100 000 in 2004, the remaining years in the 1/10000 ~ 1.5 / 100000, are maintained at 1 million and above. The sampling rate of double qualified stool samples within 14 days was between 95.2% and 100%. In addition to the follow-up rate in 2008 was 76.5%, the remaining years in between 87.5% to 100%. In addition AFP and other monitoring indicators have reached 80% of the requirements. Four poliovirus strains were isolated, all of which were vaccine strains. Conclusion The monitoring indicators of AFP in Wenzhou are obviously improved and AFP monitoring work is getting more and more perfect. Therefore, the routine immunization and intensive immunization of polio vaccine and the sensitivity and timely rate of AFP case report are enhanced. The supervision of AFP management is continued An important guarantee for keeping polio free.
