你的无知可以得到勋章，因为你解决了世界历史难题。 “While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States,”

因为轻症居多，都flooding医院，就很糟。。。
想当超级毒王？
你这么说很危险，容易反噬啊。
造成人类死亡5千万到一亿的西班牙流感是发源美国的。这个流感可是杀了当时全世界5%的人啊。
1918年流感大流行（英语：1918 flu pandemic）是于1918年1月至1920年12月间爆发的全球性甲型H1N1流感[1]疫情，此次疫情造成全世界5亿人感染[2]，5千万到1亿人死亡，传播范围达到太平洋群岛及北极地区[3]；其全球平均致死率为2.5%-5%（当时世界人口17亿人），和一般流感的0.1%比较起来极为致命，为人类历史上最致命的自然事件之一。 1918年3月4日，疫情在美国堪萨斯州芬斯顿军营出现。其后也在欧洲乃至全世界出现。一般流感通常死亡的是幼童及老年人、或是免疫功能低下的患者。但本次流行事件死者最多的却是青壮年。现今的研究将病毒株从死者的冷冻尸体中分离，显示本病毒致死的原因是因为引起细胞素风暴，导致自体免疫系统过度反应。因此免疫力最强的青壮年反而最容易引起强烈的免疫反应而死[4]。
我看到的记载都是谴责美国隐瞒维稳的罪行，当时运输军队的车上车的健康士兵很多都等不及终点站就去世了， 非常惨烈。
少叫口号，多做分析。
意大利完蛋完全是活该，第一个签一带一路的七国集团成员，苍天绕过谁？韩国也差不多，日本也有毛病！所有献媚TG的国家没一个有好下场的
反过头来看看台湾！防疫方面全球第一这才是各国抄作业的典范
西班牙流感的起源根本就没有确定，你倒是就确定了是美国
这个确实就像一个装满脏水的瓶子放到了大盆里，把大盆的水污染了，就算瓶子自己把里面清得再干净，最终也会被盆里的水反向污染的
最早病例在美国是公认的。
你再做做研究吧，看看英文网站
前几天开车正好转到american family radio， 主持说他看到seattle照片， 说空空的没有人，鼓励他的听众趁着少人去玩。。。。

Wiki在学校都是被禁止引用的，而且Wiki你再往下翻翻。主流观点就是不确定来源，法国英国甚至中国都有人猜
WIKI 没看完吧, 而且WIKi不是credible 来源，请看其他英文信息
我刚刚又去看了，已经被修改过了，而且最近一次修改是三天以前？
然后又去Google了一下H1N1的起源，结果发现当年也有指责是源于实验室的。
说H1N1主要由美国传到全世界的不为过。
最后造成"在流感季中，全世界每5人中就有1人感染甲型H1N1流感"。死亡人数至少几十万。
还有艾滋病，美国也是扩散关键，否则局限于非洲丛林和猩猩同居部落。
这是那个著名的五毛吗？
多亏当初即时切段中国来美的渠道，否则早爆发了。关键是世界应该早把中国这个乱源隔离起来，现在晚了
可是墨西哥就是起源地啊，当年墨西哥是重灾区，死亡率也高于其他国家。现在美国和欧洲新冠也很多来源于意大利呢
病源发生地本来就在加州美墨边境附近。而且当时很多国对墨西哥断航了。
H1N1全世界流行主要是从美国传到全世界应该是蛮合理的推断。否则疫病很可能就局限在墨西哥，全世界不会死那么多人。

2009年甲型H1N1流感[35]是一次由流感病毒新型变体甲型H1N1流感所引发的全球性流行病疫情。最早的已知病例是2009年3月9日墨西哥韦拉克鲁斯市格罗利亚的五岁小孩[36][37]。17日开始有美国病例，并于4月12日发生小范围群聚感染[38]。4月15日于美国确诊首例病患，疫情开始在美国加利福尼亚州、德克萨斯州爆发，其后墨西哥与美国以外的国家也开始出现案例，疫情不断蔓延[39]。
你对这个新病毒了解还是太少了，不是断航的问题，台湾，香港都没大爆发，什么原因？你现在还没明白？
台湾，香港和大陆都是同步防控，而且规格都是一样，戴口罩，减少大型集会，学校停课
戴口罩，减少大型集会十分重要，一个人可以传遍一个国家。
为什么我讲美国要大爆发，美国到现在还提倡不戴口罩，还讲大型集会没风险，这是巨大的错误。
整个美国都要为 川普无知，愚昧，自大 付出巨大的代价
中国如果像美国这样防控，现在恐怕 几千万人感染了
希望天下好人都能活着看到这一天
确实是这样的看看日本，韩国，欧盟各国，之前对美国的不要用华为5G的警告爱理不理结果全中招了还挺严重！尤其是韩国和意大利！联合国还判定TG侵略过韩国，韩国人应该是这个世界上最恨TG的，朝鲜半岛的国家统一是让TG搅黄的，TG还侵略过韩国！意大利作为七国集团第一个签一带一路的国家，苍天绕过谁？
反观人民坚决和美国走一起的加拿大澳大利亚新西兰香港和台湾，这次表现很出色
孤预测疫情结束后全球会集体右转紧密团结在以美国为核心的北约领导者周围对抗嘻嘻皮，那些亲嘻嘻皮领导人都将被他们愤怒的人民赶下台，文在寅，孔特，默克尔，马克龙等
冰冰是翻墙的吧，看的新闻嘛估计不全
我们要体谅他时不时暴露，可怜
同意你的大部分观点。
美国不宣传带口罩是没有口罩，美国3亿人只有4500万口罩，还不够六分之一的人带一天，这个病毒又不是一天两天能解决的，口罩缺口太大。
如果宣传带口罩又没有办法提供口罩，就会造成巨大的社会恐慌，未治病先乱阵脚。
（这些数字参见：http://company.stcn.com/2020/0308/15710692.shtml）
我个人理解：家里有条件带口罩的最好还是戴，但是处于各种原因不想戴口罩的，尽可能减少外出也是一个不错的办法。
自己去查查，香港，台湾，澳门的防控新闻吧
你在监狱里做梦呐

真的是任大嘴写的? 他不要命了?
突然觉得很无所谓了
最早有据可查的爆发是在美国堪萨斯的军营里
源头不会被公之于众的
CDC一个月前就这么对公众说了。你才醒？
