目的对浙江省2003年急性弛缓性麻痹(AFP)病例监测系统的工作进行评价,以便继续保持无脊髓灰质炎(脊灰)状态。方法描述流行病学分析。结果浙江省2003年AFP病例监测系统共报告AFP病例131例,<15岁儿童非脊灰AFP病例报告发病率1.79/10万,合格粪便标本采集率98.5%。分离出脊灰病毒(PV)9例,非脊灰肠道病毒10例;所有PV均为疫苗株。全省2003年口服脊灰疫苗(OPV)基础免疫报告接种率99.2%,加强免疫报告接种率96.8%。杭州、嘉兴、湖州3市开展了对0~3岁儿童OPV强化免疫活动,第1、2轮常住适龄儿童接种率分别为96.5%、96.4%,流动适龄儿童接种率分别为98.4%、96.8%;其余8个市开展了OPV查漏补种活动。结论浙江省2003年继续保持无脊灰状态。
Objective To evaluate the work of a surveillance system for acute flaccid paralysis (AFP) in Zhejiang Province in 2003 in order to maintain poliomyelitis-free (polio) status. Methods Describe epidemiological analysis. Results AFP case surveillance system in Zhejiang Province in 2003 reported a total of 131 cases of AFP cases. The incidence rate of non-polio AFP cases in children <15 years old was 1.79 / 100 000 and that of qualified stool samples was 98.5%. Nine cases of poliovirus (PV) were isolated and 10 cases of non-polio enterovirus were isolated; all PVs were vaccine strains. The province in 2003 oral polio vaccine (OPV) basic immune reporting inoculation rate of 99.2%, strengthening the immunization coverage rate of 96.8%. In Hangzhou, Jiaxing and Huzhou 3 cities, the immunization activities of OPV for children aged 0-3 years were carried out. The coverage rate of 96.5% and 96.4% for the first and second round of permanent school-age children was 98.4% and 96.8% respectively, ; The remaining eight cities carried out OPV leak detection and replanting activities. Conclusion Zhejiang Province continued its polio-free status in 2003.
