這是劍橋大學的研究報告,對新冠病毒起源和病毒株分布的研究,懂英文的可以去看看,這報告分析了A,B,C,三大類病毒株型態在世界分布的狀況,A型是蝙蝠體內的發現的病毒原型,但中國大陸和東亞的感染者普遍感染到的病毒株並不是A型,而是B型,住在武漢的美國人帶有變異的A型病毒,而A型病毒株卻大量普遍在美國和澳洲的感染者中存在,歐洲則是C型病毒株, C型並不存在中國大陸患者的sample中,用自己的智商判斷一下, 到底誰才是病毒原產國?
以下是我個人分析?
這報告第一說明美國人和澳洲人和蝙蝠同類, 所以能和新冠原形A型病毒相容,沒有A型哪來的B型, 若是A型到了東亞變異成適應東亞人體質的B型, 也就是東亞人體質絕大的可能是帶B型而非A型, 據說"美國的新冠病毒是中國人傳入的", 由於東亞人的體質容易帶B型, 那麼號稱patient zero,我們假設那些位從中國到西雅圖的中國人把身上的B型病毒傳入美國後,女兒B病株還可以又變身回讓美國人會普遍感染上的媽媽A病毒株?並且兩個月就在美國傳遍確診50萬人, 是這樣嗎? 中國人體質是帶B病毒但美國人普遍是感染A病毒, 還繼續誣賴中國啊
Forster and colleagues found that the closest type of COVID-19 to the one discovered in bats – type ‘A’, the “original human virus genome” – was present in Wuhan, but surprisingly was not the city’s predominant virus type.
Mutated versions of ‘A’ were seen in Americans reported to have lived in Wuhan, and a large number of A-type viruses were found in patients from the US and Australia.
Wuhan’s major virus type, ‘B’, was prevalent in patients from across East Asia. However, the variant didn’t travel much beyond the region without further mutations – implying a "founder event" in Wuhan, or “resistance” against this type of COVID-19 outside East Asia, say researchers.
The ‘C’ variant is the major European type, found in early patients from France, Italy, Sweden and England. It is absent from the study’s Chinese mainland sample, but seen in Singapore, Hong Kong and South Korea.
