[目的]了解AFP病例监测现况,为提高监测系统工作质量,继续巩固无脊灰状态提供科学依据。[方法]对2003～2007年黔东南州监测急性弛缓性麻痹(AFP)病例进行流行病学和监测系统质量分析。[结果]5年共报告AFP病例137例,男、女性别比1.63︰1;5岁以下占45.98%;各月均有病例发生;134例AFP病例的标本中,分离出脊髓灰质炎病毒(PV)阳性9例,均为疫苗相关株,其余均为排除脊灰病例;﹤15岁儿童非脊灰AFP病例年平均报告发病率为1.86/10万,48h内调查率98.54%,合格采样率85.4%,粪便标本7d内送达省疾病预防控制中心脊灰实验室率91.24%,随访及时率93.43%,“零”病例报告及时率90.63%,主动监测及时率89.06%。[结论]2003～2007年黔东南州AFP监测系统各项指标保持在较高水平,达到并维持了无脊灰状态。各级医疗机构及时报告病例,提高合格标本采集率,是进一步提高AFP监测质量的关键。
[Objective] To understand the status of AFP case surveillance and provide a scientific basis for improving the quality of monitoring system and continuing to consolidate polio-free status. [Methods] The epidemiological and monitoring system quality analysis of acute flaccid paralysis (AFP) in Qiandongnan Prefecture from 2003 to 2007 was analyzed. [Results] 137 cases of AFP cases were reported in 5 years, male and female ratio was 1.63︰1, while those under 5 years old accounted for 45.98%. Cases occurred in each month. Among 134 AFP cases, poliovirus ( PV) positive were all vaccine-related strains, the rest were excluded polio cases; <15-year-old children with non-polio AFP cases the average annual incidence rate of 1.86 / 100 000, 48h within the investigation rate of 98.54%, qualified sampling rate 85.4% of them were sent to Provincial Centers for Disease Control and Prevention for polio laboratory in 91 days. The timely rate of follow-up was 93.43%. The timely rate of “zero” cases was 90.63%, and the timely monitoring rate was 89.06%. [Conclusion] The indicators of AFP monitoring system in Qiandongnan Prefecture maintained a high level from 2003 to 2007, achieving and maintaining polio-free status. Medical institutions at all levels to promptly report cases and improve the collection rate of qualified samples is to further improve the quality of AFP monitoring key.
