目的分析信阳市2004-2011年急性弛缓性麻痹(AFP)病例的监测情况,更好地发挥监测系统的作用。方法对病例的流行病学特征、病原学检测结果、麻痹后就诊等情况进行分析。结果 2004-2011年信阳市AFP监测系统各项指标的完成均达到国家要求,261例病例散在分布于全市所有县区,10-11月病例较集中占29.89%;0~4岁发病最多223例,占85.44%;所有病例中有3例未进行脊灰疫苗免疫,11.11%的病例未全程免疫;粪便标本的病毒分离率为20.43%,其中脊灰病毒PV占1.28%,非脊灰肠道病毒NPEV占19.15%;乡村级医疗机构AFP病例第一次就诊的确诊率和报告率分别为50.91%和51.89%,低于市县级的80%和95.69%。结论继续加强脊灰疫苗常规免疫和强化免疫活动,保障消除免疫空白;加强乡村医务人员AFP病例监测相关知识的培训,提高对病例的识别能力和报告意识;加强AFP监测工作的督导,提高工作质量。
Objective To analyze the surveillance of acute flaccid paralysis (AFP) cases in Xinyang from 2004 to 2011, and to make better use of the monitoring system. Methods The epidemiological characteristics of the cases, the results of pathogen tests and post-numbness visits were analyzed. Results The indicators of AFP monitoring system in Xinyang from 2004 to 2011 all met the national requirements. 261 cases were scattered in all counties in the city, accounting for 29.89% of cases in the period from October to November. The highest incidence of 0- to 4-year-olds was 223 cases , Accounting for 85.44%. In all cases, 3 cases were not immunized with polio vaccine and 11.11% cases were not fully immunized. The virus isolation rate in stool samples was 20.43%, of which poliovirus PV accounted for 1.28% The virus NPEV accounted for 19.15%. The diagnosis and reporting rate of the first visit of AFP cases in village-level medical institutions were 50.91% and 51.89% respectively, lower than 80% and 95.69% of the municipal and county level. Conclusions The routine immunization and intensive immunization activities of poliovirus vaccine should be strengthened to ensure the elimination of immune blanket. The training of rural medical staffs on AFP case surveillance should be strengthened so as to improve the ability of identifying and reporting cases. Strengthen the monitoring of AFP and improve the quality of work .
