疫苗和群免悬了，唉 A 25-year-old man becomes first in the U.S. to contract coronavirus twice, with second infection ‘more severe’ It is the first confirmed case of a U.S. patient becoming re-infected with Covid-19, and the fifth known case reported worldwide. The resident of Washoe County, Nevada, who had no known immune disorders or history of significant underlying conditions, required hospital treatment on testing positive for Covid-19 for the second time. He has now recovered, though the case raises further questions about the prospect of developing protective immunity against the coronavirus. https://www.cnbc.com/2020/10/13/coronavirus-first-case-of-covid-19-reinfection-confirmed-in-the-us.html
看来是重染了变异的新冠，而不是自身隐藏病毒复发，也算是好消息，至少说明也许像中国的严防严控才是终极解决办法 Scientists said the patient caught the coronavirus on two separate occasions, rather than the original infection bouncing back after becoming dormant. This is because a comparison of the genetic codes showed “significant differences” between each variant associated with each instance of infection. “These findings suggest that the patient was infected by SARS-CoV-2 on two separate occasions by a genetically distinct virus. Thus, previous exposure to SARS-CoV-2 might not guarantee total immunity in all cases,” the authors of the study said.

哎，希望疫苗快出来吧，估计以后像流感一样年年都得打疫苗。

你这么严重？难道只能拼健康了？
看来没测，上次的样本肯定丢了。
那你要小心。science有文章说，流感容易得的人，可能在一些基因段有变异；同样的变异也会让这些人得了新冠容易重症
别指望疫苗了，只要他会变形，就没啥用
这不是说了俩virus genetic codes不一样吗
天呀！我来美国10多年,只得过一次流感。
你确定你说的流感不是感冒？一种是influnza，一种是普通的RSV引起的，去年那种广泛流行两个株有人得两次的已经是比较少见的
美国流感实在吓人，我好多年前得过一次，感觉就是像要死了，本来一直自信满满觉的在国内历练过五毒不侵，结果，压根不是同一级别的感冒
1. 已經證明是不同病毒株。 2. 該名25歲患者已康復出院，這個報導是基於一篇最近才發表的柳葉刀論文進行探討，並不是最近才查出二次感染。
flu跟普通感冒本来就不是一回事，跟国别没关系吧。我以前在国内得过一次流感，那是第一次感受到那么严重的感冒，站都站不起来了，高烧不退，身体可虚荣了。来美国以后我每年都打flu shot，倒是再也没得过了。
你确定你得的是流感？病毒引发的流感要靠抗生素治疗？华人大妈起码的科学知识都没了吗？
first case 和 几百万感染的，
这时候我不会 panic， 再等等。。。
像中国这样一刀切的严控严防只有极权独裁国家做的到，民主国家没有这可能。
现在很关键的问题是，病人好了以后，病毒在体内是否完全消失，还是像HIV一样永久隐藏，随时可能复发，那中国就有几万，美国几百万带毒者，到处都是星星之火可以燎原，那才真没戏了
不过看中国的控制，如果是这种情况，应该到处都是自主复发的此起彼伏，所幸没出现，所以也许最坏的情况不会发生，那人类还有救~
