目的:分析2014年度苏州市姑苏区外环境监测的数据与该区2014年12月—2015年1月间确诊报告的3例人感染H7N9病毒病例的流行病学特征,以便进一步了解外环境与人感染H7N9病毒发病之间关联,为采取切实可行防控人禽流感措施提供依据。方法:对苏州市姑苏区所有存在禽类交易的农贸市场进行外环境采样,对确诊病例与病例的密切接触者进行个案调查并采样送检,分析其对流行病学特征。结果:3例病例发病时间都与去过农贸市场的外环境监测阳性一致,其病例呈高度散发,病例之间无流行病学关联,发病时间均为冬季,均有农贸市场暴露史;将病例采取隔离治疗,对密切接触者进行医学观察、疫点终末消毒;建议政府对检出阳性标本的市场暂停交易活禽,未检出阳性的市场应加强管理,落实定期休市与消毒的制度,控制疫情扩散。结论:具有活禽交易的农贸市场实施采样,其阳性与3例具有农贸市场暴露史的人感染高H7N9禽流感病毒病例的发病存在关联,暂未发现人传人的证据;早期发现和救治患者是提高患者预后的关键,应加强人感染H7N9禽流感病毒疫情的监测,并根据《苏州市活禽交易管理办法》相关规定,向政府建议对检出阳性标本的市场暂停交易活禽,未检出阳性的市场应加强管理,落实“四分开”和定期休市与消毒的制度。
