武漢肺炎病毒現時的主流品種為D614G，一道較為簡易的說明方法就是原來的D614品種變異成為G614品種。563Please respect copyright.ＰＥＮＡＮＡqUZtjR5nju

563Please respect copyright.ＰＥＮＡＮＡFaEcF4Uwrt
而根據GISAID公開資料庫記錄，G614品種最先在1月24日的四川病毒樣本出現。563Please respect copyright.ＰＥＮＡＮＡRpCEiqeMvB

（圖2）何解G614品種能夠成為主流，一直是科學家想解答的問題。563Please respect copyright.ＰＥＮＡＮＡU5H1hzn8Sb

之前所獲得的實驗數據，大多是從病毒一小段的部份、或者是合成病毒獲取結果，沒能百分百反映現實。563Please respect copyright.ＰＥＮＡＮＡpraYK7Ml3g
563Please respect copyright.ＰＥＮＡＮＡYDPAxuA5ws
直至最近，才有科學家利用真實存在的武肺病毒進行實驗。563Please respect copyright.ＰＥＮＡＮＡfHEq44opLc
563Please respect copyright.ＰＥＮＡＮＡpEGF53ENU9
（圖3）在研究中（Ref1)，科學家將D614品種及G614品種以1 : 1的比例從倉鼠的鼻孔注入其體內。563Please respect copyright.ＰＥＮＡＮＡeEjyKoqNKR
563Please respect copyright.ＰＥＮＡＮＡHpJeJs3QQm
563Please respect copyright.ＰＥＮＡＮＡ7skZxEyV3V
如果最終G614品種/D614品種的比例大於1的話，亦即是代表G614品種在繁殖方面比D614品種更為優勝。563Please respect copyright.ＰＥＮＡＮＡ2KeGzAK4gf
563Please respect copyright.ＰＥＮＡＮＡ33RfSeMLAX
（圖4）倉鼠受病毒感染7日後，鼻孔、氣管及肺部個別區域的G614品種/D614品種均大於1，顯示G614品種在上述區域有著較佳的繁殖優勢。563Please respect copyright.ＰＥＮＡＮＡ6XA14UBPgr
563Please respect copyright.ＰＥＮＡＮＡRdfI7sgdgF
563Please respect copyright.ＰＥＮＡＮＡPzSqmjo6Mz
同時在實驗室的人體肺部細胞中，就算用上D614品種及G614品種以9 : 1的比例方式感染，G614品種/D614品種在其後感染日子均呈大於1的狀態，更進一步顯示G614品種的繁殖優勢。563Please respect copyright.ＰＥＮＡＮＡQauUqTdY9M
563Please respect copyright.ＰＥＮＡＮＡOmtXkDu89U
563Please respect copyright.ＰＥＮＡＮＡYzPyPkWrR4
（圖5）科學家同時亦發現，G614品種的病毒在各種溫度上均比D614品種相對為穩定。563Please respect copyright.ＰＥＮＡＮＡX0Hw23wJpU
563Please respect copyright.ＰＥＮＡＮＡevLKxStL0w
563Please respect copyright.ＰＥＮＡＮＡL5FaazDbrK
不過好消息是，對抗D614品種的抗體，其對抗G614品種品種效率並無任何損傷。563Please respect copyright.ＰＥＮＡＮＡn5dL9E3t2N
563Please respect copyright.ＰＥＮＡＮＡCHPeF1HwA2
這亦即間接顯示出以D614品種作原材料的疫苗，其產生的抗體亦能有效對抗G614品種病毒，而事實上現今亦有疫苗是利用G614品種作原材料，奈何是鄰國出品。563Please respect copyright.ＰＥＮＡＮＡcM7k583MjM

（圖6）至於近來在挪威發現的新變種M439K品種，基於是新發現的關係，現時醫學界及學術界均無任何學術文章作詳細研究其特性。563Please respect copyright.ＰＥＮＡＮＡbhCq57EvwH

莫論病毒變種與否，只需一個乞嗤，病毒就已經不需近距離接觸，便能透過體液傳播至他人。563Please respect copyright.ＰＥＮＡＮＡlKp5bkaCKH
563Please respect copyright.ＰＥＮＡＮＡhbJGaXUYmB
將「新變種」及「不需近距離接觸」串連在一起的報導手法，有著混淆視聽的成份，並不可取。563Please respect copyright.ＰＥＮＡＮＡGFixPrO1vQ
