目的分析铁岭市2005—2014年10年间急性弛缓性麻痹(AFP)病例监测情况,提高全市AFP监测系统质量。方法对铁岭市10年间报告的AFP病例进行描述流行病学分析。结果 10年间共报告AFP病例76例,报告发病率在1.40/10万~3.24/10万之间。7—12月报告病例56例,占73.68%;病例以5岁以下儿童为主,占56.58%;服苗史≥3剂次63例,占82.89%;合格标本采集率为89.47%。从病例粪便标本中分离到1例2份Ⅰ型脊髓灰质炎(脊灰)疫苗株病毒,5例10份非脊灰肠道病毒(NPEV)。结论铁岭市AFP病例监测系统运转较好,为继续保持无脊灰状态,应进一步加强脊灰疫苗常规免疫接种率,提高监测系统质量。

Methods The epidemiological analysis of AFP cases reported in Tieling during the past 10 years was described. Results A total of 76 cases of AFP were reported in 10 years, with a reported incidence rate of 1.40 / 100,000 to 3.24 / 100,000. In July-December, 56 cases were reported, accounting for 73.68%. The cases were mainly children under 5 years old, accounting for 56.58%. 63 cases were treated with clothing seedlings ≥ 3 times, accounting for 82.89%. The sampling rate of qualified samples was 89.47%. Two cases of type I poliomyelitis (poliovirus) vaccine strain and five cases of non-polio enterovirus (NPEV) were isolated from the stool samples.

In order to maintain the polio-free status, routine vaccination rate of poliovirus should be further strengthened to improve the quality of monitoring system.
