早前,挪威公共研究所表示於國內發現一種前所未見的變種冠狀病毒,並表示新變種病毒更具傳染性。是繼早前美國從豬隻中發現變種冠狀病毒後,再次發現另一種傳播率比現時新冠肺炎更高的冠狀病毒。
據報指,變種的新冠病毒於特隆赫姆市發現,由10月16日至18日期間已有8名當地市民受感染。
科學家表示,變種的冠狀病毒名為M439K,屬冠狀病毒B.1.5.的子群組,病毒的結構令它更容易依附於細胞上並感染身體中的細胞。
而M439K病毒的另一個特性是其傳染性比現時的新冠病毒更高,特隆赫姆市首席醫生指,不少病例均不需要近距離接觸亦被感染,加上病發速度快。
另外,外國有機構針對多個新冠病毒案例進行研究,發現病毒會隨時產生變異並且累積,意味著當有新患者受感染都有可能令病毒變種成新的病毒,而隨著病毒不斷變異,傳染力可能會越來越高。
