总统唐纳德·特朗普周四三次谎称疾病控制和预防中心研究发现绝大多数戴口罩的人都感染了新冠肺炎，但一些专家表示，总统以一种潜在的危险方式曲解了这些数据，因为疾控中心仍然建议当不可能保持社交距离时，每个人都会在公共场合戴上面具。
特朗普周四在接受美国全国广播公司新闻采访时表示，“就在几天前，他们发表声明说，85%戴口罩的人都会感冒。”
主持人萨凡纳·古斯瑞立即推后。
“他们没这么说，”格思里说。“我知道那项研究。”
“嗯，我就是这么听说的。这就是我看到的，”桀骜不驯的特朗普回答道。

当天早些时候，总统在北卡罗来纳州格林维尔的一次集会上发表了同样的错误言论。
“看看所有的面具。你知道，他们一直在说，‘没人戴面具，戴面具。’尽管如此，他们今天还是拿出了东西。你看疾控中心了吗?85%戴口罩的人都抓到了，好吗?”特朗普告诉挤满的观众。
周四早上接受福克斯新闻特朗普的采访说“然后你会看到疾控中心发表声明说85%戴口罩的人会感冒，”问，“这是怎么回事?”

2020年10月15日，美国总统唐纳德·特朗普在北卡罗来纳州格林维尔的皮特-格林维尔机场举行的集会上发表讲话。
疾病预防控制中心报告特朗普指的是上个月发表的一篇文章，该文章发现外出就餐比其他社交活动更容易感染新冠肺炎病毒。这项研究不是为了观察口罩的有效性，而是调查了314名有症状的人的行为冠状病毒7月在全国11个特定地点进行测试。
研究发现，在154名测试呈阳性的有症状的人中，85%的人表示，他们在发病前的14天里“总是”或“经常”戴口罩——特朗普的数字来自哪里。它还发现，在其余160名报告症状但测试呈阴性的研究人员中，88.7%的人说他们“总是”或“经常”戴口罩。
这项研究本周在社交媒体上引起了关注，用户对戴口罩的有效性提出了质疑，此后，疾控中心周三下午在推特上表示，“与不戴口罩的人相比，更多戴口罩的人受到感染的解释是不正确的。”
特朗普政府前食品和药物管理局局长斯科特·戈特利布(Scott Gottlieb)博士周五上午反驳了总统的不准确解释，并强调口罩在减缓传播方面是有效的。
戈特利布说:“口罩不是万灵药，但它们会给你提供一定程度的保护。”讲述CNBC。“在另一种选择是肆虐的流行病将迫使某种经济混乱的环境中，我宁愿尝试让每个人都戴上口罩，我宁愿尝试让他们戴上高质量的口罩，因为我们知道这将减缓传播。会有影响的。”
他指出，大多数关于口罩有效性的研究表明，戴口罩可以通过阻止呼吸道飞沫来减少病毒的传播。

这项研究的合著者之一，范德比尔特大学医学中心健康数据科学中心的联合主任克里斯托弗·林赛，讲述CNN周四在一封电子邮件中称特朗普歪曲了数据。
“数据表明，在一组已经表现出促使他们进行病毒测试的症状的患者中，没有统计证据表明测试阳性和测试阴性的患者之间佩戴口罩的行为存在差异，”林赛说。
Trump falsely cites CDC data on mask-wearing, catching COVID-19
PresidentDonald Trumpfalsely claimed three times on Thursday that a Centers for Disease Control and Preventionstudyfound the vast majority of people who wear a mask contract COVID-19, but several experts say the president misinterpreted the data in a potentially dangerous way as theCDC still recommendseveryone wear a mask in public when social distancing isn't possible.
Trump, during a town hall with NBC News Thursday, said that "just the other day, they came out with a statement that 85% of the people that wear masks, catch it."
Moderator Savannah Guthrie immediately pushed back.
"They didn't say that," Guthrie said. "I know that study."
"Well, that's what I heard. And that's what I saw," a defiant Trump replied.

The president made the same erroneous claim during a rally in Greenville, North Carolina, earlier in the day.
"Look at all the masks. You know, they keep saying, 'Nobody wears a mask, wear the mask.' Although then, they come out with things today. Did you see CDC? That 85% of the people wearing a mask catch it, OK?" Trump told the packed audience.
And a Thursday morning interview with Fox News Trumpsaid, "Then you see CDC comes out with a statement that 85% of the people wearing masks catch it," asking, "What's that all about?"

The CDCreportTrump was referring to was published last month and found that dining out raised the risk of COVID-19 infection more than other social activities. The study was not designed to look at mask effectiveness but surveyed the behaviors of 314 symptomatic people who sought outcoronavirustesting at 11 particular sites around the country in July.
It found that of 154 symptomatic people who had tested positive, 85% said they had worn a mask either "always" or "often" over the 14 days prior to the onset of their illness -- where Trump's number came from. It also found that of the remaining 160 people in the study who reported symptoms but had tested negative, 88.7% said they had worn a mask either "always" or "often."
After the study gained attention on social media this week with users raising questions on the effectiveness of wearing a mask, the CDC tweeted on Wednesday afternoon that "the interpretation that more mask-wearers are getting infected compared to non-mask wearers is incorrect."
Dr. Scott Gottlieb, former Food and Drug Administration chief in the Trump administration, pushed back on the president's inaccurate interpretation Friday morning and stressed that masks are effective in slowing the spread.
"Masks are not a panacea, but they're going to afford you a level of protection," GottliebtoldCNBC. "In an environment where the alternative is having a raging epidemic that's going to force some kind of economic dislocation, I'd rather try to get everyone in masks and I'd rather try to get them in high-quality masks because we know it's going to slow down the transmission. It's going to have an impact."
He noted most studies on the effectiveness of masks have shown that wearing one reduces the transmission of the virus by blocking respiratory droplets.

One of the study's co-authors, Christopher Lindsell, co-director of the Health Data Science Center at Vanderbilt University Medical Center,toldCNN in an email Thursday that Trump misrepresented the data.
"The data suggest that among a group of patients who are already showing symptoms that prompted them to get testing for the virus, there was no statistical evidence of a difference in mask wearing behavior between those who tested positive and those who tested negative," Lindsell said.
"This is very different from the question of whether wearing masks prevents you becoming infected with the virus, and it is also different to the question of how many or what percentage of people who wear masks contract the virus. The study was not designed to answer these questions."
Trump's continued false claims come as he pushes for an end to COVID-19 restrictions, repeating on Thursday what's become a mantra to him throughout the pandemic, "The cure cannot be worse than the problem itself."
