2008—2010年灵山县儿童急性弛缓性麻痹病例流行病学分析

Epidemiological analysis of AFP cases of children in Lingshan County from 2008-2010

目的进一步做好急性弛缓性麻痹(AFP)病例的监测工作,巩固无脊髓灰质炎成果。方法采用描述流行病学方法对灵山县2008—2010年AFP病例的流行病学特征和监测系统运转情况进行分析。结果灵山县2008—2010年分别报告AFP病例9、8和12例,报告发病率分别为2.58/10万、2.59/10万、和3.94/10万,AFP病例监测系统各项指标均达要求,合格粪便标本采集率为96.42%(27/28),分离出非脊髓灰质炎肠道病毒6例,占20.68%;分离出脊髓灰质炎病毒Ⅰ型1例,占3.45%,经国家脊髓灰质炎实验室鉴定后排除。结论灵山县儿童AFP病例监测系统运转情况良好。做好常规免疫、强化免疫、查漏补种和AFP病例合格标本的采集工作,提高首诊报告率,是有效维持无脊髓灰质炎状态的重要工作。
