目的分析铁岭市2001-2010年急性弛缓性麻痹(AFP)病例监测情况,保持全市无脊髓灰质炎(脊灰)状态。方法对2001-2010年全市报告的AFP病例进行描述流行病学分析。结果 2001-2010年铁岭市共报告AFP病例69例,无脊灰确诊病例,AFP病例报告发病率在1.17/10万~2.16/10万之间。各县(市、区)年均报告发病率在1.02/10万~3.94/10万之间,其中昌图县有5年报告发病率未达到1/10万的标准。下半年报告病例49例,占71.01%。AFP发病者中以5岁以下儿童为主,占53.62%。病例中服苗史≥3剂次53例,占76.81%。合格粪便样本采集率为92.75%。从3例AFP病例粪便样本中分离到非脊灰肠道病毒,分离率为4.35%。结论铁岭市AFP病例监测系统各项指标,以市为单位,均达到国家标准。为保持无脊灰状态,应保持高水平脊灰疫苗免疫接种率,提高AFP病例监测系统质量。
Objective To analyze the surveillance of cases of acute flaccid paralysis (AFP) in Tieling between 2001 and 2010, and to keep poliomyelitis-free (polio) status in the city. Methods Epidemiological analysis of AFP cases reported from 2001 to 2010 in the city was performed. Results A total of 69 AFP cases were reported in Tieling City from 2001 to 2010. There were no confirmed cases of poliovirus. The incidence of AFP cases was between 1.17 / 100,000 and 2.16 / 100,000. Each county (city, district) reported an average annual incidence of 1.02 / 100,000 to 3.94 / 100,000, of which Changtu County has a 5-year reporting rate of less than 1/10000. In the second half of 2009, 49 cases were reported, accounting for 71.01%. AFP onset of children under 5 years of age, accounting for 53.62%. Cases of clothing seedlings history ≥ 3 times 53 cases, accounting for 76.81%. The sampling rate of qualified stool samples was 92.75%. Non-polio enterovirus was isolated from the stool samples of 3 AFP cases, with a separation rate of 4.35%. Conclusion The indicators of AFP case monitoring system in Tieling City are all up to the national standard by the municipal unit. To maintain a polio-free status, a high level of polio vaccine immunization coverage should be maintained to improve the quality of AFP case monitoring systems.
