目的了解眉山市2000年实现无脊灰目标证实后急性迟缓性麻痹(AFP)病例监测系统运转情况。方法应用中国免疫规划监测信息管理系统和Excel软件对数据进行统计。结果2001-2007年共报告AFP病例111例,<15岁儿童AFP病例年均报告发病率2.71/10万,48h调查率94.59%,14d内双份合格大便采集率90.09%,7d内大便送达率96.39%,60～75d随访率95.49%。7年中各区县均有3个以上指标不合格;111例AFP病例中,发病无明显季节性,男女之比1.9:1,5岁以下占65.77%,无免疫史和免疫史不详占12.61%;非脊灰肠道病毒感染占14.41%,格林巴利综合征(GBS)占22.52%,无高危AFP病例报告。AFP病例主动监测系统运转正常,脊灰疫苗免疫接种率在93%以上。结论眉山市2001-2007年继续保持无脊灰状态,各项监测指标均达到卫生部要求。今后仍需保持敏感的AFP病例监测系统,保持高水平的脊灰疫苗免疫接种率。
Objective To understand the operation status of AFP case monitoring system after the achievement of polio-free target in Meishan in 2000. Methods The data of China immunization program monitoring information management system and Excel software were used for statistics. Results A total of 111 cases of AFP were reported in 2001-2007. The average annual incidence of AFP was 2.71 / 100000 in children <15 years old, 94.59% in 48h and 90.09% in 14d. The stool was delivered within 7 days The rate of 96.39%, 60 ~ 75d follow-up rate of 95.49%. In 7 years, all districts and counties had three or more indicators failed; in 111 cases of AFP, the incidence was not significantly seasonal, the ratio of men to women 1.9: 65.77% under 1,5 years of age, no history of immunization and immune history is unknown accounted for 12.61% ; Non-polio enterovirus infection accounted for 14.41%, Guillain-Barre syndrome (GBS) accounted for 22.52%, no high-risk AFP cases reported. AFP cases active monitoring system is functioning properly, the polio vaccine immunization rate of 93%. Conclusion Meishan continued to maintain a polio-free status from 2001 to 2007 with various monitoring indicators meeting the requirements of the Ministry of Health. In the future, it is still necessary to maintain a sensitive AFP case monitoring system and maintain a high level of polio vaccine coverage.
