JAMA Intern Med:浙江地区一次新冠肺炎公交车传播案例分析研究

2020-09-07 MedSci原创 MedSci原创

本次队列研究表明,与COVID-19确诊患者同乘的接触者感染SARS-CoV-2的风险更高,在高度封闭的环境中,必须考虑SARS-CoV-2病毒在空中传播的可能性

寻找严重急性呼吸系统综合征冠状病毒2型(SARS-CoV-2)气溶胶(即空气传播)传播的证据具有重大的公共卫生意义。近日研究人员利用COVID-19疫情的流行病学证据,探讨SARS-CoV-2感染的潜在传播途径。

研究人员分析了浙江省一次社区COVID-19疫情数据。在2020年1月19日,128人乘坐2辆公交车(60[46.9%]接触者来自公交车1,68[53.1%]接触者来自公交车2)往返100分钟,参加了一个150分钟的礼拜活动。在公交车2上有一名确诊患者。研究人员考察了乘坐公交车1(n=60)和公交车2(n=67[确诊病人除外])和所有其他参加礼拜活动的个人(n=172)感染SARS-CoV-2的风险。根据与确诊病人的距离将公交车座位分为高风险区和低风险区,在这两辆公交车上,中央空调都处于室内循环模式。研究的主要终点为核酸检测证实的SARS-CoV-2感染。

在128名接触者中,15名(11.7%)为男性,113名(88.3%)为女性,平均年龄为58.6岁。 在公交车2上,68名接触者中有24人(35.3%)在事件发生后确诊COVID-19,但与此同时,在公交车1的60名接触者中无一人感染。 在参与礼拜活动的172名接触者中,有7人(4.1%)感染。 在公交车2感染COVID-19的风险比在公交车1高34.3%,并且与参加礼拜活动的所有其他个体相比,患COVID-19的风险高11.4倍。在公交车2中,高风险区域的接触者与低风险区域的接触者相比,COVID-19感染风险中度提高但不显著。

本次队列研究表明,与COVID-19确诊患者同乘的接触者感染SARS-CoV-2的风险更高,在高度封闭的环境中,必须考虑SARS-CoV-2病毒在空中传播的可能性。

JID:流感患者或可通过气溶胶传播流感病毒

流感被认为主要是通过飞沫传播(微粒直径>5μm,并且在3-6英尺内沉淀);然而在某些特殊情况下,空气传播(微粒直径<5μm ,在空气中处于悬浮状态)也被认为与流感传播有关,比如流感病毒通过气溶胶进行传播。在美国职业安全与卫生管理局(OSHA)和公共卫生流行病学专家间,关于空气传播在流感发生过程所起作用的讨论早已展开,特别是在2009-2010年流感季节期间H1N1病毒株大规模爆发之时。 B
