目的　为进一步做好急性弛缓性麻痹 (AFP)病例监测 ,巩固无脊髓灰质炎 (脊灰 )成果。方法　对宁夏回族自治区 2 0 0 3年AFP病例的流行病学特征及监测系统运转情况进行描述性流行病学分析。结果　全自治区共报告AFP病例 1 9例 ,<1 5岁儿童非脊灰AFP病例报告发病率 1 4 2 / 1 0万 ;合格粪便标本采集率为 94 .7% ;分离到 1株Ⅲ型脊灰病毒 ,为疫苗株 ;非脊灰肠道病毒分离率为 1 0 5%。AFP病例监测系统各项指标均达到要求。根据病毒学分类标准 ,报告的AFP病例均为脊灰排除病例。口服脊灰疫苗强化免疫活动第 1轮报告接种率为 97. 4 6% ,第 2轮为 97.51 %。接种率快速评估结果为 ,第 1轮调查目标儿童 1 1 1 7人 ,服苗率为 94.0 0 % ;第 2轮调查目标儿童1 1 46人 ,服苗率为 95.99%。结论　做好常规免疫和AFP病例合格粪便标本的采集 ,提高AFP病例首诊报告率 ,加强AFP病例分类专家诊断小组的活动 ,是无脊灰证实阶段重要的工作 Objective To further monitor cases of acute flaccid paralysis (AFP) and consolidate poliomyelitis-free (polio) outcomes. Methods Descriptive epidemiological analysis of the epidemiological characteristics of AFP cases and monitoring system operation in 2003 in Ningxia Hui Autonomous Region was conducted. Results A total of 19 AFP cases were reported in the Autonomous Region. The incidence of non-polio AFP cases in children <15 years old was 14 2/10 000; the detection rate of qualified stool samples was 94.7%; 1 type III ridges The gray virus is a vaccine strain; the non-polio enterovirus isolation rate is 105%. AFP case monitoring system indicators meet the requirements. According to the standard of virological classification, the reported cases of AFP were all cases of polio-negative cases. The first round of oral immunization with oral polio vaccine reported 97.46% of vaccinations and 97.51% of the second round. The rapid assessment of inoculation rate showed that in the first round of survey, 1,117 children were targeted and the rate of dressing was 94.0%. In the second round of survey, 1146 children were targeted, with the rate of 95.99%. Conclusion The routine immunization and collection of qualified stool specimens for AFP cases, improving the first report rate of AFP cases and strengthening the activity of expert diagnosis group of AFP case classification are important tasks in the verification of poliovirus
