来来来，你的英文鸡然是白人恩客教的，那你一腚读得懂下面这段原文吧？
你一腚知道最后一句“ This viral journey from Wuhan to Mexico, lasting a month, is documented by 10 mutations in the phylogenetic network.“是什么意思吧？
One practical application of the phylogenetic network is to reconstruct infection paths where they are unknown and pose a public health risk. The following cases where the infection history is well documented may serve as illustrations (SI Appendix). On 25 February 2020, the first Brazilian was reported to have been infected following a visit to Italy, and the network algorithm reflects this with a mutational link between an Italian and his Brazilian viral genome in cluster C (SI Appendix, Fig. S1). In another case, a man from Ontario had traveled from Wuhan in central China to Guangdong in southern China and then returned to Canada, where he fell ill and was conclusively diagnosed with coronavirus disease 2019 (COVID-19) on 27 January 2020. In the phylogenetic network (SI Appendix, Fig. S2), his virus genome branches from a reconstructed ancestral node, with derived virus variants in Foshan and Shenzhen (both in Guangdong province), in agreement with his travel history. His virus genome now coexists with those of other infected North Americans (one Canadian and two Californians) who evidently share a common viral genealogy. The case of the single Mexican viral genome in the network is a documented infection diagnosed on 28 February 2020 in a Mexican traveler to Italy. Not only does the network confirm the Italian origin of the Mexican virus (SI Appendix, Fig. S3), but it also implies that this Italian virus derives from the first documented German infection on 27 January 2020 in an employee working for the Webasto company in Munich, who, in turn, had contracted the infection from a Chinese colleague in Shanghai who had received a visit by her parents from Wuhan.

【环球时报-环球网报道 记者 李司坤】福克斯新闻4月15日援引多位消息人士的话宣称，美国政府怀疑新冠病毒是因为武汉病毒研究所安全措施松懈而意外泄漏，美国总统特朗普同日回答福克斯提问时表示，美国政府正在进行彻查。4月16日，有外媒记者在中国外交部例行记者会上就此事提问，发言人赵立坚回应称，关于新冠病毒源头和传播途径问题，中方立场是明确的，我们始终认为这是一个科学问题，应该交由科学家和医学专家去研究。
“我想提醒你注意的是，世卫组织负责人已经多次表示，没有任何证据表明新冠病毒是在实验室产生的。世界上很多知名医学专家也都认为所谓实验室泄露等说法毫无科学依据。”赵立坚指出，流行性疾病是人类共同的敌人，国际社会只有合理应对，才能战而胜之。中方将继续与各国同舟共济、守望相助、携手赢得这场人类同重大传染病的斗争。
