特朗普的主张:
总统唐纳德·特朗普在周一晚上的竞选集会上“谎称”这部小说冠状病毒18岁以下的“几乎不影响任何人”,主要威胁老年人和患有潜在疾病的人健康条件，根据华盛顿邮报。
事实检查:
特朗普自相矛盾。在3月份接受《华盛顿邮报》副主编鲍勃·伍德沃德采访时，他承认“许多年轻人”受到了影响，并承认他淡化了病毒的风险。不清楚特朗普说这话时指的是哪个年龄组，但我们知道新冠肺炎是如何影响儿童和年轻人的。
2020年9月21日，星期一，在俄亥俄州斯旺顿，唐纳德·特朗普总统在一次竞选集会上发表讲话。
自3月份以来，越来越多的证据表明，年轻人并不是不受冠状病毒如最初所想。根据疾控中心冠状数据追踪器最近对143，273例死亡的分析显示，843例(约0.6%)发生在30岁以下的人群中，而88例(约0.06%)发生在18岁以下的人群中。
最近MMWR报告关于21岁以下人群中与新冠肺炎相关的死亡，疾病控制和预防中心的研究人员显示，婴儿、儿童、青少年和年轻人中与非典相关的死亡有近四分之三发生在10至20岁的人群中，18至20岁的人群以及西班牙裔、黑人、美洲印第安人和有潜在疾病的人群中的比例过高。
年轻人也有患新冠肺炎综合症的严重风险。最近的美国医学会内科学研究在大约3200名18至34岁的人中，有684人(约21%)需要特别护理，331人(约10%)需要呼吸机。90人，约3%死亡。
该人群的不良结局率低于报告的患有新冠肺炎病的老年人的不良结局率，但高于报告的青年人中其他疾病的不良结局率。例如，作者发现新冠肺炎年轻成年人的死亡率是同一年龄组心脏病发作死亡率的两倍多。病态肥胖、高血压和糖尿病与该年龄组严重并发症的更大风险相关，这与我们在老年人中看到的相似。事实上，患有一种以上这些疾病的年轻人所面临的风险与没有这些疾病的中年人所面临的风险相当。
在所有年龄的儿童和成人中，先前存在的医疗状况无疑增加了新冠肺炎症的严重并发症和死亡的风险。值得注意的是，这些人的死亡原因是新冠肺炎，而不是他们潜在的疾病或年老。
Fact check: Trump's claim about whether coronavirus affects young people
Trump's claim:
PresidentDonald Trump"falsely claimed" at a Monday night campaign rally that the novelcoronavirus"affects virtually nobody" younger than 18 and mainly threatens seniors and people with underlyinghealthconditions, according to theWashington Post.
Fact check:
Trump contradicted himself. In a March interview with Washington Post associate editor Bob Woodward, he acknowledged that "plenty of young people" were affected and admitted that he'd downplayed the risks of the virus. It's not clear exactly which age group Trump was referring to when he said that, but here's what we know about how COVID-19 affects kids and young adults.
President Donald Trump speaks at a campaign rally, Monday, Sept. 21, 2020, in Swanton, Ohio.
Since March, evidence has been building that young people aren't as impervious tocoronavirusas initially thought. According to theCDC Covid Data tracker, a recent analysis of 143,273 deaths revealed that 843, about 0.6%, occurred in people younger than 30, while 88, about 0.06%, occurred in people younger than 18.
In a recentMMWR reporton COVID-19-related deaths in persons under 21, Centers for Disease Control and Prevention researchers showed that that nearly three quarters of SARS-CoV-2-associated deaths among infants, children, adolescents and young adults have occurred in persons aged 10 to 20 years, with a disproportionate percentage among those aged 18 to 20 years and among Hispanics, Blacks, American Indians and persons with underlying medical conditions.
Young adults also are at risk for severe complications of COVID-19. A recentJAMA Internal Medicine studyof roughly 3,200 people ages 18 to 34 showed that 684 people, about 21%, required intensive care and 331, about 10%, required ventilators. Ninety people, about 3%, died.
The rates of poor outcomes in this population were lower than those reported for older adults with COVID-19, but higher than the rates reported for other diseases in young adults. For example, the death rate the authors found for COVID-19 in young adults is more than twice the death rate for heart attacks in the same age group. Morbid obesity, high blood pressure and diabetes were associated with greater risks of serious complications in this age group, which is similar to what we see in older adults. In fact, young adults with more than one of these conditions faces risks comparable to those observed in middle-aged adults without them.
In children and adults of all ages, pre-existing medical conditions undoubtedly increase the risk for severe complications and death from COVID-19. It's important to note that the cause of death in these individuals is COVID-19, not their underlying disease or old age.
