广西学校细菌性肠道传染病疫情特点及其影响因素分析

　　【摘要】 目的  了解广西近年发生于学校的细菌性肠道传染病爆发疫情的流行病学特点及影响处理效果的因素，为预防与控制学校肠道传染病的流行提供依据。 方法  收集广西2001-2004年各级疾病预防控制机构对学校爆发疫情的调查处理报告和资料，对资料进行流行病学描述并进行多因素逐步回归分析。 结果  64起爆发疫情中伤寒副伤寒35起、细菌性痢疾15起、感染性腹泻14起，共报告病例5795例。疫情多发于乡镇和城乡结合部的寄宿学校（82.81%），以春、秋季节尤其是秋季开学为高发，传播途径以水型为主（65.63%）。多因素逐步回归分析，首例与疫情报告时间间隔、病例隔离措施、病种和传播途径影响疫情处理效果。 结论  农村学校以水型传播为主的细菌性肠道传染病是当前广西学校卫生工作的突出问题;疫情报告是否及时、病例隔离措施是否落实是影响疫情处理效果的关键因素。
