【摘要】 目的分析绵阳市急性迟缓性麻痹(AFP)病例流行病学特征,发现工作中的薄弱环节,为进一步提高全市免疫规划工作质量,维持全市无脊灰状态提供策略。方法收集整理全市2012-2017年AFP病例流行病学调查及日常督导等资料,运用描述性流行病学方法进行统计分析。结果绵阳市2012-2017年非脊灰AFP病例报告发病率均维持在2/10万以上,监测敏感性较高。地区分布主要集中在总人口50万以上的县市区,每年均有病例报告,占全市病例报告数的55.65%,AFP病例呈散发状态,各病例间无流行病学联系。季节性不明显,11、12月及1月病例报告相对较多,与近年流感高发,急性肌炎病例增多有关。发病人群以1～9岁组为主,占79.13%。4～14岁组脊灰类疫苗免疫史不详比例占2.53%,不足4剂次的占16.46%。结论绵阳市AFP病例监测敏感性总体较好,但监测医院在病历管理的规范性及每旬主动监测落实性上还有待提高,学校预防接种证查验及流动儿童管理上还存在薄弱环节,需进一步加强。更多还原

【Abstract】 Objective To analyze the features of AFP cases in Mianyang and find out the weak points. To expand the immunization programs, and provide the strategies for consolidating the polio-free situation. Methods Collect and investigate the AFP cases in the whole city in 2012-2017. Analyze and gather statistics by describing the epidemic. Results The incidence of AFP is 2 out of 100,000, which lead to a high sensitivity. The AFP cases were highly sporadic, mainly distributed in all counties that has a population of 500,000 and account for 55.65% of all. Every year the cases had been reported and showed no epidemic relationship. November, December, and January had more cases, possibly related to the more flu infections that cause acute myositis. The seasonal changes weren’t significant. Children at the age of 1 to 9 were the main patients, which was 79.13% in total. The rate of AFP vaccine between 4 and 14 years old is 2.53% in total. The number of children that didn’t get 4 doses of medicine is 16.46%. Conclusion Although the sensitivity gauging of AFP in Mianyang city is excellent, the approach nitidity gauging of AFP in Mianyang city is excellent, the monitoring needs improvement. We should check the immunization cards of students. We need to enhance the management of migrant children at the same time.更多还原
