目的 为全面评价甘肃省 2 0 0 3年消灭脊髓灰质炎 (脊灰 )工作 ,保持无脊灰状态。方法 对急性弛缓性麻痹(AFP)病例监测系统和口服脊灰疫苗 (OPV)免疫资料进行分析。结果 2 0 0 3年共报告AFP病例 1 2 8例 ,<1 5岁儿童非脊灰AFP病例报告发病率 1.94/1 0万 ,其它监测指标均达到卫生部和世界卫生组织的标准。AFP病例中格林 巴利综合征占 54 %。从AFP病例粪便标本中分离出脊灰病毒 (PV)疫苗株 6株 ,其它肠道病毒 1 1株 ,病毒分离率为 1 4.1 7% ,所有PV阳性株经中国疾病预防控制中心病毒病预防控制所国家脊灰实验室鉴定为疫苗株。OPV常规免疫报告接种率 >95% ,估算接种率 71 %。 2 0 0 3/2 0 0 4年部分地区强化免疫活动共免疫 0～ 3岁儿童 4944 98人次 ,两轮报告接种率均 >98% ,估算接种率均 >90 %。结论 自 1 993年至今已连续 1 1年未发生脊灰野病毒引起的病例 ,继续保持无脊灰状态 ,但部分地区存在着监测和免疫薄弱区域 ,应在今后的工作中采取并有效落实各项措施
The purpose is to comprehensively evaluate the eradication of poliomyelitis (polio) in Gansu Province in 2003 and to maintain a polio-free status. Methods AFP cases surveillance system and oral poliovirus (OPV) immunization data were analyzed. Results A total of 122 cases of AFP were reported in 2003, and the incidence of non-polio AFP in children <15 years old was 1.94 / 100 000. Other monitoring indicators met the standards of Ministry of Health and World Health Organization. Guillain-Barre syndrome accounts for 54% of AFP cases. Six strains of poliovirus (PV) vaccine were isolated from the stool specimens of AFP and 11 other enterovirus strains were isolated. The virus isolation rate was 11.7%. All PV-positive isolates were controlled by the Chinese Center for Disease Control and Prevention The national polio laboratory identified as vaccine strains. OPV routine immunization coverage of> 95%, estimated vaccination rate of 71%. In 2009, 4944 98 children aged 0-3 years were co-immunized in some areas during 2004-2010. The coverage rate of both reports was> 98% and the estimated vaccination rates were> 90%. CONCLUSION: Poliovirus-free cases have not been reported for 11 consecutive years since 1993, and remain polio-free. However, there are areas where monitoring and immunization are weak in some areas and should be taken and effectively implemented in future work Measures
