无毛阉狗，睁开你的狗眼看看。这是CDC官网的报告：“Seven sequences clustered in Group B, which includes early sequences detected in China and other global sequences, as well as other sequences from New York.”

呵呵，还真有那么一两个懂点英文的。
那好，我就花点时间，继续教教你。
来看看这篇发表在PNAS的文章
https://www.pnas.org/content/117/17/9241
别说不信这里的数据啊，这是英国德国病毒学专家研究的结果，发表在美国国家科学院自己的院刊上。
看完后，来说说病毒的A，B，C之间的先后关系，和他们各自分布在哪里。
然后再看看你自己刚刚放的毒 "裆霉断章取义、颠倒黑白、坑蒙拐骗的又一明证。"
觉不觉得脸有点被扇的有点疼，有点发红发烧。。。
Abstract
In a phylogenetic network analysis of 160 complete human severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) genomes, we find three central variants distinguished by amino acid changes, which we have named A, B, and C, with A being the ancestral type according to the bat outgroup coronavirus. The A and C types are found in significant proportions outside East Asia, that is, in Europeans and Americans. In contrast, the B type is the most common type in East Asia, and its ancestral genome appears not to have spread outside East Asia without first mutating into derived B types, pointing to founder effects or immunological or environmental resistance against this type outside Asia. The network faithfully traces routes of infections for documented coronavirus disease 2019 (COVID-19) cases, indicating that phylogenetic networks can likewise be successfully used to help trace undocumented COVID-19 infection sources, which can then be quarantined to prevent recurrent spread of the disease worldwide.

呵呵，还真异味自己懂点英文？因为是小学博士教的？
看看你自己挑的Abstract里的原话：
“In contrast, the B type is the most common type in East Asia, and its ancestral genome appears not to have spread outside East Asia without first mutating into derived B types, pointing to founder effects or immunological or environmental resistance against this type outside Asia. ”
知道“ancestral"、"founder effects"是什么意思吗？
你查，你细查。
查完后，你再来说说病毒的A，B，C之间的先后关系，谁先谁后。
知道你认识26个字母，但别学小学博士，只知道数字母顺序哈。
“觉不觉得脸有点被扇的有点疼，有点发红发烧。。。” 哈哈哈，你烧，你细烧。
没有那金刚钻，就别干无毛习地的活。记住啦。
裆中央的屎，舔起来容易洗干净难呐，比引刀自宫还难。😂😂😂
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.A不代表就和武汉无关，B也不代表发源地是武汉，C也不代表起源是欧洲。只是区别变异，不是几代顺序
据@CGTN ，美国疾控中心17日发布报告说，特朗普早在2月2日就匆忙发布对中国游客的入境禁令，可直到3月13日才宣布对欧洲国家实行入境限制，但到3月8日，新冠病毒早就开始在纽约市的社区传播。此外，报告还揭示了一个发现：纽约市流行的毒株与中国武汉毫不相干。纽约州长科莫针对该报告回应称，因为政府应对疫情失措，病毒传到了纽约市，导致这么多美国人丢掉了性命。
