CDC稱病毒空氣傳染力強 新指引籲嚴守6呎社交距離

國家疾病控制及預防中心(CDC)週日(20日)更新疫情指引,稱新冠病毒能以空氣為媒介,「透過呼吸道飛沫或微粒,例如氣溶膠之中的微粒」感染他人,更是傳染力最強的病毒。

CDC以往已經表示,新冠病毒主要影響6呎範圍內的密切接觸者,並且可透過感染者咳嗽、打噴嚏、說話時產生的呼吸飛沫傳播。

該部門在18日更新網站資料,形容新冠病毒除了普遍在密切接觸者之間傳播外,患者咳嗽、打噴嚏、唱歌、說話甚至呼吸後,產生的呼吸飛沫、微粒或氣溶膠都同樣會停留在空氣中,繼而影響其他人。

更新內容還表示,民眾一旦透過口鼻、氣管和肺部吸入這些微粒,便會受到感染,這也是新冠病毒目前最主要的傳播方式。

愈來愈多證據也顯示,水滴、空氣傳播的微粒能夠懸浮在空氣中,並且飄到6呎之外。在通風不良的室內環境中,這種風險尤其較高,更建議國民「盡可能與其他人保持至少6呎距離」,並繼續要求人們戴口罩,生病時要留在家中隔離,並且使用淨化器來過濾室內的空氣。
