在一项尚未经过同行评议的研究中,研究团队请25名专业歌手对着漏斗状的器具呼吸、讲话、咳嗽和唱歌。然后他们测量了由此产生的气溶胶 WhileoneroutebywhichCovid-19 spreadsisviabigdroplets, largelyproducedwhensomeonecoughsandwhichfalltothegroundwithinacoupleofmetres, Reidsaidaerosolswereanotherpossibleroute, notingsuchtinydropletscanlingerintheair.
新冠病毒传播的一条路径是通过飞沫,大多是在某人咳嗽时产生,在一两米的距离内会落到地面。里德表示,气溶胶是另外一条可能的传播路径,他指出微小的飞沫会悬浮在空气中。
