目的 评价广西壮族自治区2 0 0 3年维持无脊髓灰质炎(脊灰)状态工作。方法 采用描述流行病学分析方法。结果 广西壮族自治区2 0 0 3年急性弛缓性麻痹(AFP)病例监测系统报告AFP病例16 9例,<15岁儿童非脊灰AFP病例报告发病率1 4 7/ 10万,其中临床符合脊灰2例,疫苗相关麻痹型脊灰9例,Ⅰ型疫苗变异脊灰病毒病例1例。口服脊灰疫苗(OPV)常规免疫和强化免疫活动运行良好,覆盖率保持在较高水平。但2 0 0 3年仍有2 8个县无病例报告,16个县AFP病例报告发病率<1/ 10万。农村病例占全部AFP病例的79 .2 8% ,乡、村两级的首诊报告率只有2 1. 95 %。计划免疫薄弱区域和免疫空白依然存在。疫苗变异脊灰病毒病例的发生是对维持无脊灰的预警信号。结论 要继续维持无脊灰状态必须保持高质量的AFP病例监测和高的OPV接种率。
Objective To evaluate the maintenance of non-polio (polio) status in Guangxi Zhuang Autonomous Region in 2003. Methods Describe methods of epidemiological analysis. Results AFP cases surveillance system in Guangxi Zhuang Autonomous Region reported 163 cases of AFP in 2003, and the incidence of non-polio AFP cases in children <15 years old was 147,000 / 2 cases, 9 cases of vaccine-associated paralytic poliovirus, and 1 case of variant poliovirus type I vaccine. Oral polio vaccine (OPV) routine immunization and intensive immunization activities run well, coverage remained at a high level. However, there are still 28 county-free case reports in 2003, and the incidence of AFP cases in 16 counties was <1 / 100,000. The rural cases accounted for 79.28% of all cases of AFP. The first report rate at village and village levels was only 21.95%. Weak areas of planned immunity and immune gaps still exist. Vaccine Variants Polio virus cases occur as early warning signs of maintenance of poliomyelitis. Conclusion High quality AFP case monitoring and high OPV vaccination rates must be maintained to maintain polio-free status.
