CDC Director变CDC老板。CDC Director在真实感染数据未出炉前，目前预估已被感染人数可能介于30 and 60 million之间，到你这立刻变 已有6千万人感染了新冠。唉。。

As many as 60 million Americans could have been infected with coronavirus, Director of the US Centers for Disease Control and Prevention Dr. Robert Redfield told the Journal of the American Medical Association Thursday.
The CDC released a report in June, published in JAMA, showing an infection rate in the United States of about 10%. Redfield said at the time he believed testing had missed 90% or more of cases.
Redfield said Thursday an infectionrate of between 10-20% translates into as many as 60 million people who may have already been infected, but there’s not really any good data on the numbers yet.
“We’re in the process of obviously following up with the report that we did in JAMA that kind of let us understand that maybe for the 2 million cases we diagnosed, we had an estimated 20 million people infected,” Redfield said in the video interview.
“We've now expanded that throughout the country, so very large surveillance work in progress,” he said.
Redfield said he didn’t want to speculate on the number of Americans who may actually be infected with the virus, but he did offer an estimate.
“I really want to be data driven but there is enormous geographic variation. I can tell you that we have some areas that we're looking at less than 1% and we have other areas we're looking at 20%,” he said.
“I think if you're going to do a crude estimate, somewhere between 30 and 60 million people -- but let's let the data come out and see what the data shows.”
Confirmed cases: As of Thursday night, at least 5,573,501 coronavirus cases have been recorded across the US, according to Johns Hopkins University. The total includes at least 174,248 deaths

CDC老板前2天作报告给出来美国新冠已感染人数的最新估计，不是几百万，而是6千万人。也就是说近20%的美国人已有抗体了。
本玩家根据疫情数据统计估算得出了到今天为止，美国已被感染过的人数(有抗体的人数) 应该接近2千万至2千300万人之间，这个数字虽然比CDC老板的6千万低很多，全美抗体人口还只有6-7%。但也远远超过了官方新冠已确认的感染人数。 本玩家和CDC至少都一致认为，美国实际新冠感染人数远远超过确认感染人数。LOL
美国很多县有抗体的比率惊人，很多地方已经达到/接近群体免疫了。有空本玩家也许会公布US 人口TOP100 县人口COVID 抗体比率数据。

反正我觉得实际感染人数大大超过公布的统计，很多无症状/很轻微症状被感染者只能估计。西班牙和意大利都有严重的第一感染暴发峰。但西班牙有第二波感染峰，意大利没有。奇怪。病毒变异的缘故？其他因素？
could have been infected. 不是实际感染发生之前，对感染人数的估计。是疫情感染已经发生了，对感染情况的估计。
不是你指的疫情发生前或感染之前。 原文特指在真实感染统计数据未出炉之前对未来数据的估算，你的时间点与此文章的焦点不同啊。 别歪。。读文章得看愿意，抓重点焦点啊。。
在“XX之前”对未来的预测当然能叫预先评估“预估” 也可说对将可能达到的数据的估算“估计”。
“I think if you're going to do a crude estimate, somewhere between 30 and 60 million people -- but let's let the data come out and see what the data shows.”

你的理解错误显然是因不了解随机抗体测试是什么意思，为什么随机测试数据抗体可以估计已被感染人口比率的数学根据啦，LOL
