冠状病毒何时结束？我们在美国达到了顶峰？
根据一项新的预测，到12月1日，该病毒可能夺走近30万人的生命。
随着世界继续与冠状病毒大流行的严酷现实作斗争，大多数（如果不是全部的话）公民的日常生活发生了巨大变化：整个国家和城市都被封锁，并且安全距离已经强制执行。
但随着越来越多的地方取消家庭订单，重新开放关闭的企业，现在每个人都在想同样的事情：最糟糕的情况是否已经过去，如果没有，冠状病毒大流行何时结束？简短而简单的回答是：没有人确切知道。这完全取决于冠状病毒爆发本身以及我们如何应对。
尽管如此，SARS（严重急性呼吸综合征）和Covid-19之间的相似性：两者都是冠状病毒，并具有类似的DNA，Ravina Kullar，Pharmd，MPH，专家管理公司的传染病研究员和传染病学会美国专家讲述健康. 它们也有相同的呼吸道飞沫主要传播途径和相似的潜伏期。
但随着2003年SARS的爆发，全世界只有8098人患病，根据疾病控制和预防中心在八个月的时间里，只有774人死亡。另一方面，2019冠状病毒疾病已经超过2000万例，自爆发以来已经有760000人死亡，其中包括超过160000人死亡。
Kullar博士说，1918 PANDEMAXY的流感可能表明与Covid-19更类似的模式，但即使这不是一个完全的比较。“我认为你可以看到的是[所谓的西班牙语]流感是一种非常相似的模式，就有多少人受到影响，有多少人被杀，以及社会疏散措施如何快得足够快，”Kullar博士说。
供参考疾控中心说据估计，在1918年流感大流行期间，全世界有5000万人死亡，其中约67.5万人死于美国。据CDC报道，1918年流感大流行始于1918年3月，经过多次病毒传播，1919年2月左右在美国开始消退。
因为很难确定2019冠状病毒疾病何时会以其他流行病的轨迹为结束，一些专家提出一个比“冠状病毒何时结束”更好的问题，而是“冠状病毒何时会达到高峰？”
库利亚尔博士指出来自卫生计量和评估研究所的数据（IHME）是华盛顿大学医学院的一个人口健康研究中心。自二月以来，2019冠状病毒疾病专家、计算机科学家和流行病学家一直在追踪和预测美国的COVID-19。最初，目标是预测死亡人数何时达到高峰，以及卫生系统何时会出现医疗需求激增。IHME的模型发现，在流感大流行的最初几天，美国每天的死亡人数和住院人数在4月中旬达到了第一个高峰，主要集中在纽约市地区。4月15日，根据C2019冠状病毒疾病的调查，59940人被送往医院。新冠病毒追踪项目.
此后，病例开始2019冠状病毒疾病的发病率开始下降，直到六月底再次发生再发，美国地区的太阳辐射带最终在7月24日达到另一个峰值，共有59716个COVID-19住院。
华盛顿乔治敦大学奥尼尔国家和全球卫生法研究所高级学者、医学博士丹尼尔·鲁西（Daniel Lucey）用涨潮和低潮的比喻来描述他所看到的全国范围内冠状病毒感染高峰的持续模式。”整个夏天到秋天，海浪都会持续不断，”他在最近的美国传染病学会简报会上告诉记者。
基本上：即使美国的一股浪潮消退，另一波可能在拐角处.
IHME对疫情下一阶段的预测反映了在全国城市发生公众抗议后，美国人的流动性增加，社会距离放松。该研究所现在预测，几乎30万人将死亡从12月1日到2019冠状病毒疾病。
希望是政府和个人的行动将减少传播，但目前的模型显示整个9月每天的死亡人数急剧增加。”如果美国无法控制9月份的增长，我们可能会在10月、11月以及接下来的几个月面临恶化趋势，如果我们预期的流感大流行遵循肺炎季节性，”IHME主管Christopher Murray医学博士说。
You might have wild dreams when you're ill—fever can do that. But bizarre or emotionally intense fever dreams are not recognized as a symptom of COVID-19.
