COVID-19 is believed to have originated in horseshoe bats and transferred to humans via an intermediary animal such as a pangolin. The epicentre is thought to be a Wuhan seafood market. Surprisingly however, researchers found the A variant was not Wuhan’s dominant virus type. Instead, mutated versions of A were found in Americans that lived in Wuhan and A-type viruses were also found in patients in Australia and the US. Type B is derived from A and separated by two mutations. This was the main type found in Wuhan city and across East Asia. However it has not been found much beyond East Asia, suggesting a “founder event” in Wuhan or some form of resistance to the strain outside of Asia. Instead, a third virus strain known as C – which is the “daughter” of B – has been found across Europe and is also present in Sydney, according to the virus tree.
There are two subclusters of A which are distinguished by the synonymous mutation T29095C. In the T-allele subcluster, four Chinese individuals (from the southern coastal Chinese province of Guangdong) carry the ancestral genome, while three Japanese and two American patients differ from it by a number of mutations. These American patients are reported to have had a history of residence in the presumed source of the outbreak in Wuhan. The C-allele subcluster sports relatively long mutational branches and includes five individuals from Wuhan, two of which are represented in the ancestral node, and eight other East Asians from China and adjacent countries. It is noteworthy that nearly half (15/33) of the types in this subcluster, however, are found outside East Asia, mainly in the United States and Australia.
英文都读不懂，也来献丑，这文章正打TG的脸。 看文章学英语了，一直有人想看我翻译文章，现在出来献丑了！ 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. A的突变版本的病毒是在居住在武汉的美国人中发现的，并且大量的A类型病毒在美国和 澳大利亚被发现。 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. 武汉的主要病毒类型B，在东亚病人中流行。然而，这一种群在没有进一步突变的情况 下没有跨区域流行，暗示了武汉的奠基者事件，或者说，阻力抵挡了这一类型在东亚以 外的地区传播，据研究人员说。 科普一下 the founder effect The founder effect is a case of genetic drift caused by a small population with limited numbers of individuals breaking away from a parent population. The occurrence of retinitis pigmentosa in the British colony on the Tristan da Cunha islands is an example of the founder effect. https://zh.wikipedia.org/zh-cn/奠基者效应 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. C种群是欧洲主要类型，在法国，意大利，瑞典和英国的早期病人中被发现。他们在中 国大陆的研究采样中缺失，但是在新加坡，香港和韩国被发现。 这几段上面说明几个问题： 第一，美国人主要流行的A类型，有武汉居住史。 第二，美国的大流行类型，不是从欧洲来的，而是从中国来的。 第三，中共隐瞒了C类型数据。 最重要的一点：只在武汉才发现有奠基者效应！

“mutated versions of A were found in Americans that lived in Wuhan” What do you call this mutated A ? A-type? “Type B is derived from A and separated by two mutations.” Does “derived” mean type B mutated from type A too? So they call it type b?
五毛不懂英文。告诉你文章第一段就是说病毒来自中国， Australians diagnosed with coronavirus could be suffering from one of two different strains of the disease, one of which is a “daughter” to the original strain found in China, new research has found.

所有的病菌生物都是为了适应当地的环境来演变的。如果A型不适应武汉亚洲人身体环境，当初根本不会变成A型好不好。变成B型并在亚洲传开说明B型适合亚洲人。而A型适合美国澳大利亚说明是在那里的环境适应和演变的。世界上没有那么巧合的事情，一个不适应当地的病菌到外国人身上就如鱼得水，马上就适应了。这个是不可能的事情。 美国的A型刚开始症状也是非常轻的，传播越多，变异也越多。目前美国的新冠杀伤力越来越强。纽约市不缺医疗设备病床和ICU死亡率已经突破6%，7%再过几天就到了。
报道说的非常清楚了，澳大利亚和美国发现A型，在武汉的美国人发现A型。武汉人民是B型！
A型在美国和澳大利亚被发现。大家看清楚了！武汉的美国人，和“大量”的A型病毒在美国和澳大利亚！如果是武汉先有的，不应该武汉有大量的A型病毒吗
======
与蝙蝠体内新冠病毒最接近的病毒类型是A型，即原始的人类病毒基因组A型。该病毒基因组在武汉出现，但不是武汉地区的主要病毒类型。在居住于武汉的美国人身上发现了突变的A型病毒，在来自美国和澳大利亚的患者中也发现了大量的A型病毒。 武汉患者的主要病毒类型是B型，B型也在东亚各地的患者中存在，然而，如果没有进一步的变异，它不会在该地区以外传播太多。 C型病毒是欧洲的主要类型，在来自法国、意大利、瑞典和英国的早期患者中均发现C型病毒。C型病毒没有出现在该研究中的中国大陆患者样本中，但在新加坡、中国香港和韩国都曾发现C型病毒。
研究结果认为，A型病毒与蝙蝠和穿山甲体内发现的病毒关系最密切，研究人员将其描述为疫情暴发的根源。B型病毒由A型衍生而来，被两个突变分开，然后C型反过来又是B型的“女儿”。

你个白痴不会自己去读论文吗，不知道什么叫ancestral genome吗，人家文章写的很清楚了只不过本着一种科学态度来探讨。
不过目前看来这个mutation好可怕一种mutation可以强烈感染一个地方的人

我觉得她是50pct of each
🛋️ 沙发板凳
但目前的观点是各个 strain 差别非常小，没有致病力的大差别。
放屁。我就是澳洲人。澳洲的病毒有两波，第一波是过年假期的中国游客！第二波是邮轮和欧美疫情起来以后的游客澳洲政府网站有明确数据，来源最多的是欧洲。全世界的源头就是中国武汉，提这个是一个纪念和哀悼！
这是楼主一贯的行为。
不屏蔽，就是看它怎么作妖。

赞翻译和清晰分析。
澳大利亚早就说了中共病毒是武汉来的
你自己翻译的： A的突变版本的病毒是在居住在武汉的美国人中发现的，并且大量的A类型病毒在美国和
澳大利亚被发现。
武汉的美国人，和“大量”的A型病毒在美国和澳大利亚！如果是武汉先有的，不应该武汉有大量的A型病毒吗？你的逻辑有问题啊！
A型到了武汉，因为环境关系和中国人身体基因和澳大利亚和美国人不同，传到中国人身上就容易变异了，变成B型，A型在中国人身上不起作用。中国人去欧洲再传给老外，又容易变异成C型，应该B型在老外身上也传播力不强。

就说你说是五毛，不识字，果不其然人家澳大利亚完整的一句话，被你的国翻译得断章取义，下半句那个"美国的病毒也是中国传过来的"你怎么不说?
请问读过书吗，会看英文吗，学过GRE 逻辑吗？疫情之下人比较直白，对不住了！
present不奇怪啊，因为武汉有发现美国人有A型。而且大量A型在澳大利亚和美国发现。武汉肯定有A型，可是不多。就像欧洲肯定也有A型和B型，可是也不多。
这是从mitbbs剽窃来的，还是两个handles背后一个人？
蠢货一枚，学过科学吗，武汉感染的人那么多，这篇文章分析了多少。而且你不知道共党下令销毁标本这些遮掩的鬼祟行为吗，不让WHO去武汉，现在连发个文章都要批准。为啥？！因为 2 月有篇武汉的教授的文章分析病毒来源于实验室然后撤稿，被老美找出来了。不懂去上个本科或者高中学位。中国搞成这样都是你们这种信仰党没有思想的愚民惯的，如果你在美国应该让移民局好好审查你们的背景。

我目前是美国公民，在美国拿到的硕士学位，在华尔街金融公司任职20年左右，现在已经40岁，退休状态。非要说我是五毛。随便说，反正改变不了任何事情。
剑桥的研究报告会传遍全世界，大家都会读到。
真替雇你的公司感到羞愧。不会是国内白手套洗钱的公司吧。别说你是美国硕士，丢不起这个人。
翻译得很好！ 我不是抬杠，就事论事。你第一段英文翻译，文中没说 large number。 我觉得这样说的好像是美国和澳洲的大量感染是中国来的有争议性。我不肯定，但我觉得美国被欧洲感染的比较多。
下面红框引文是你们总理说的，到底你放屁还是你们总理放屁呢？
既然澳大利亚没有从美国来的病毒，都是中国和欧洲的错。
为什么澳大利亚流行美国a毒株，而不是武汉和欧洲的b和c。tom hanks夫妇又是怎么回事。
人傻，被卖了还帮着数钱，说的就是你这号的。
20岁就进华尔街金融公司了，硕士毕业？ 18岁国内本科毕业来美国？神童咩？
请问读懂英文不？混了这么多年难道天天在华尔街说中文？
笑死 明明快50了 说自己40 还真会round down
我在华尔街帮我工作的公司赚了很多钱，我也学到了很多，所以我自己也可以早退休了。雇我的公司谢谢我还来不及呢，想要留我多做几年，我婉拒了，钱是赚不完的，时间留给自己太舒服开心了。
你太负面了，要不就羞愧，要不就丢不起脸。做人得阳光一点，世界是美好的，生活是舒怡的。即使在纽约的疫情里，也可以开开心心的做自己喜欢做的事情。
中国上传的数据相比中国的病例数是非常少的，而且时间和地点都非常有限。只上传很少的数据是怕其他数据说明什么吗？
时代广场溜娃的睿大妈，领7毛就变成华尔街退休的用私人飞机精英了。
四十几也是四十嘛。快五十多难听啊。
你再怎样说我差也避免不了我现在所有问题都解决了，已经早退休，不愁钱，不愁生活。

承认自己智障了？拿钱说事了？
我没有说武汉没有啊，如果A和B比起来少很多，而且澳大利亚和美国是大量的A型. 从时间上看是A在其他国家先传播开，才来武汉的啊。外国A型都传开了，全中国都应该有很多A啊。可是中国只是B啊
