醫用口罩擋不住新冠傳播?美研究:病毒恐穿透防護 編輯 王翊綺 報導 2020/04/07

口罩是醫療必備物資。 新冠肺炎(COVID-19)肆虐全球,許多專家呼籲民眾常洗手、戴口罩,可有效阻絕病毒。不過最新研究卻發現,「無論是醫
療口罩或棉口罩,都無法有效過濾病毒。」雖未顯示穿戴口罩是否減低飛沫飛行的距離,
也未測試N95口罩的防護性,詳細內容仍待進一步研究,但「口罩的實用性」仍引起外界
關注。
根據外媒報導,美國醫學期刊「內科學年刊」近日有一份實驗報告,內容顯示「無論是醫療口罩或是布口罩都無法完全過濾病毒」。該研究以南
韓首爾的2間醫院為實驗地點,找來4名新冠肺炎確診病患進行對照,並將培養品放在距離
病患18公尺的地方,請患者咳嗽5次。結果發現,「病患佩戴的口罩外層,比內層的污染
來得多」,顯示新冠病毒可穿透防護,到達口罩外層,並散布至環境中。雖然實驗範圍小,也僅使用醫療口罩及布口罩,未使用N95口罩進行實驗,實
驗報告也沒有說明病毒外漏原因;目前尚不明白是否與「患者咳嗽力道」或「病毒大小」
有關。但若依照實驗結果來看,「口罩無法有效過濾病毒」,恐顛覆以往人們對於防疫方
有關。但若依照實驗結果來看,「口罩無法有效過濾病毒」,恐顛覆以往人們對於防疫方
法的認知
3.心得/評論:
明天口罩股價不知道會如何反應?
不過有總比沒有好吧!
什麼能代替口罩成為新貨幣?
