美最新研究!病毒最愛塑膠與不鏽鋼 遇上銅四小時就消失
2020/03/17 11:29
國際中心/陳佳鈴報導
武漢肺炎(COVID-19、新冠肺炎)具有超強的傳染力,因此專家多次提醒應該戴口罩、常
洗手。至於病毒(Covid-19)的傳播力究竟有多強,美國研究人員將病毒嘗試性散布在家
庭和醫院常見的 7 種材料上發現「塑膠」、「不鏽鋼」表面存活時間最久,長達三天。
病毒最不喜歡「銅」,短暫停留 4 小時就消失了。

過去科學家已知,一些如流感病毒光是觸摸表面,便可讓人短短幾秒內沾上數百萬個病毒
顆粒,但為了更精確了解新型冠狀病毒的運作方式,遏制流行,華盛頓大學與美國國立衛
生研究院(NIH)研究人員,找來 7 種在家庭和醫院常見的材料,將病毒散佈到表面,在
等待幾小時至數天後,再擦拭材料表面並檢查病毒是否仍可感染培養皿的細胞。結果顯示
,病毒最喜歡的材料「塑膠」、「不鏽鋼」,研究人員 3 天後仍可收集到病毒。而這兩
種材質是ㄧ般民眾生活中最容易接觸到的,像是扶梯把手、門把、任何塑膠製品,最好都
要先使用酒精消毒。

研究指出,病毒最不喜歡「銅」,短暫停留 4 小時就消失了。而氣溶膠的狀態,病毒能
保持活力近 3 小時。值得一提的是,研究也證實病毒至少可沾附在紙箱包裹或手機外殼
長達 1 天。雖然新型冠狀病毒的傳染力看似很強,但冠狀病毒其實很容易殺死。2 月時
德國相關研究人員便表示,只要花 1 分鐘使用酒精清潔表面,病毒顆粒便可從 100 萬迅
速減少到 100 個,有效降低感染風險。
3. 不知道這樣的研究结果,是否有機會能促進銅的需求,而讓銅的價格自低點有機會反彈
呢?
