乔·拜登总统的药检呈阳性新冠肺炎(新型冠状病毒肺炎)周四早上，白宫首次宣布。

79岁的拜登有“非常轻微的症状”，正在服用帕昔洛韦，白宫新闻秘书郭佳欣·让-皮埃尔在一份声明中说。

白宫新冠肺炎应对协调员Ashish Jha博士说，拜登正在经历流鼻涕，干咳和疲劳。

Jha说，总统在周三白天感觉“完全正常”。据总统的医生凯文·奥康纳(Kevin O'Connor)博士说，拜登的症状始于周三晚上，然后他在早上作为例行检查的一部分检测出阳性，Jha说。

拜登在推特上说，他“做得很好”，“一直很忙!”

Jean-Pierre表示，随着拜登在白宫“隔离期间继续履行办公室的全部职责”，每天都将提供更新。

Jean-Pierre说，密切接触者，“包括在昨天的旅行中与总统互动的任何国会议员和任何媒体成员”，将在周四得到通知。

拜登(姓氏)周三去了马萨诸塞州的萨默塞特在那里他宣布了应对气候变化的行政措施。拜登在外面发表了演讲，并会见了当地官员。

她说，总统将被隔离工作，直到他的检测结果呈阴性。

让-皮埃尔说:“他今天上午一直通过电话与白宫工作人员保持联系，并将通过电话参加他今天上午在白宫计划的会议，并从住所进行放大。”。

拜登全面接种疫苗，接受了两次加强剂;他的第二次加强注射是在3月30日。

她补充说，拜登最后一次接受新冠肺炎病毒检测是在周二，当时他的检测结果为阴性。

白宫办公厅主任罗恩·克莱恩(Ron Klain)在给工作人员的一封电子邮件中说，“我们已经说了一段时间，总统-像其他任何人一样-有很大的可能性可以得到乔维德，我们已经为这种可能性做好了准备。”

第一夫人吉尔·拜登周四早上在底特律的检测结果呈阴性，她的办公室表示，她将在密歇根和佐治亚州度过这一天。她的办公室表示，她将继续遵循疾控中心的指导，进行掩蔽和保持距离。

杰哈在周四的新闻发布会上说，因为拜登接种了疫苗并接受了双重加强，他“患严重疾病的风险大大降低了”。“他还在接受一种非常有效的抗病毒药物的治疗，这进一步降低了他患严重疾病的风险。”

杰哈说，病毒已被送去测序，以确定总统的新冠肺炎变种。

美国广播公司新闻首席医学记者詹妮弗·阿什顿博士说，治疗中最大的因素将是总统的年龄。

“这就是为什么，”她说，“毫不奇怪，他正在接受抗病毒药物帕罗西汀的治疗。临床试验表明，它在降低严重新冠肺炎病风险方面有89%的有效性，这意味着住院或死亡。”

阿什顿强调，“他将在白宫受到总统私人医生的密切监视，如果任何事情看起来都朝着错误的方向发展，我绝对希望他会住院，如果没有其他事情比更密切的观察更好的话。但请记住，白宫不像你的家或我的家——他们可以在那里进行大量的医疗监测、观察和测试。”

前总统唐纳德·特朗普是短暂住院2020年10月在沃尔特里德医疗中心，在他的新冠肺炎检测呈阳性后。

2021年12月，食品药品监督管理局批准辉瑞公司开发的抗病毒药丸Paxlovid用于12岁及以上的人。

在五天的疗程中，病人每天服用两次，每次三片。这种药丸被誉为改变游戏规则的药物，因为它是第一种不需要输液的新冠肺炎治疗方法，使患者服用更加方便。

Paxlovid由两种药物组成:通常用于治疗艾滋病毒和艾滋病的利托那韦(ritonavir)，以及辉瑞公司开发的用于增强第一种药物强度的抗病毒药物nirmatrelvir。它们一起阻止了病毒用来在人体细胞内复制自身并扩散到全身的一种酶。

尽管越来越多的报道称服用帕罗西汀后出现反弹现象，但阿什顿表示，益处仍大于任何风险。

“如果拜登总统服用了帕罗西汀，出现了这种所谓的反弹现象，最糟糕的情况会是什么?只是更多的时间被隔离。基于这种药物在降低住院和死亡风险方面的临床试验，其益处是显而易见的，这就是为什么给他这种药物治疗是一个直接而简单的临床决定，”她说。

副总统四月份新冠肺炎病毒检测呈阳性。安东尼·福奇博士，总统在疫情的一名高级顾问上个月检测呈阳性。

President Biden tests positive for COVID-19

President Joe Biden tested positive forCOVID-19for the first time Thursday morning, the White House said.

Biden, 79, has "very mild symptoms" and is takingPaxlovid, White House press secretary Karine Jean-Pierre said in a statement.

Biden is experiencing a runny nose, dry cough and fatigue,WhiteHouseCOVID-19Response CoordinatorDr. Ashish Jha said.

The president felt "totally normal" during the day Wednesday, Jha said. Biden’s symptoms started Wednesday evening, according to the physician to the president, Dr. Kevin O’Connor, and he then tested positive in the morning as a part of routine testing, Jha said.

Biden tweeted that he's "doing great" and "keeping busy!"

Jean-Pierre said an update will be provided every day as Biden "continues to carry out the full duties of the office while in isolation" at the White House.

Close contacts, "including any Members of Congress and any members of the press who interacted with the President during yesterday’s travel," will be informed on Thursday, Jean-Pierre said.

Bidentraveled to Somerset, Massachusetts, on Wednesdaywhere he announced executive actions to address climate change. Biden delivered his speech outside and met with local officials.

Sen. Elizabeth Warren, D-Mass., who was with Biden at his event Wednesday, tested negative on Thursday, a spokesperson said.

The presidentgreeted Ukrainian first lady Olena Zelenskaat the White House on Tuesday.

Vice President Kamala Harris, who was with the president on Tuesday, tested negative Thursday morning. Her office said she'll remain masked and continue her schedule as planned.

Zelenska said she doesn't have any symptoms. She said a negative test was required ahead of Tuesday's meeting, adding that she plans on re-testing.

The president will work in isolation until he tests negative, she said.

"He has been in contact with members of the White House staff by phone this morning, and will participate in his planned meetings at the White House this morning via phone and Zoom from the residence," Jean-Pierre said.

Biden is fully vaccinated and received two boosters; his second booster shot was March 30.

Biden was last tested for COVID-19 on Tuesday, when he tested negative, she added.

White House chief of staff Ron Klain said in an email to staff, "We have said for some time that there was a substantial possibility that the president -- like anyone else -- could get COVID, and we have prepared for this possibility."

First lady Jill Biden tested negative Thursday morning in Detroit and will keep her full schedule in Michigan and Georgia through the day, her office said. She will continue following CDC guidance with masking and distancing, her office said.

Jill Biden said she spoke with the president Thursday morning and said "he’s doing fine" and "feeling good."

Sen. Bob Casey, D-Pa., tweeted that he spoke with Biden on the phone and that he "sounded great and is in good spirits."

Because Biden is vaccinated and double boosted, his "risk of serious illness is dramatically lower," Jha said at a Thursday press briefing. "He is also getting treated with a very powerful antiviral that further reduces his risk of serious illness."

The virus has been sent for sequencing to determine the COVID-19 variant the president has, Jha said.

ABCNews Chief Medical Correspondent Dr. Jennifer Ashton said the biggest factor in treatment will be the president's age.

"That is why," she said, it's "no surprise that he's being treated with the antiviral pill Paxlovid. It's been shown in clinical trials to be 89% effective in reducing the risk of severe COVID-19 illness, meaninghospitalization or death."

Ashton stressed, "He is going to be closely monitored at the White House by the personal physician of the president, and if anything looks like it is going in the wrong direction, I absolutely expect that he would behospitalized, if nothing else than for more close observation. But remember, the White House is not like your home or my home -- they can do a lot of medical monitoring and observation and testing right there."

Former President Donald Trump wasbriefly hospitalizedat Walter Reed Medical Center in October 2020 after he tested positive for COVID-19.

Paxlovid, an antiviral pill developed by Pfizer, was approved by the Food and Drug Administration for those aged 12 and older in December 2021.

Patients take three pills twice daily over the course of five days. The pill was hailed as a game-changer because it was the first COVID-19 treatment that did not require an infusion, making it more convenient to give to patients.

Paxlovid is made up of two medications: ritonavir, commonly used to treat HIV and AIDS, and nirmatrelvir, an antiviral that Pfizer developed to boost the strength of the first drug. Together, they prevent an enzyme the virus uses to make copies of itself inside human cells and spread throughout the body.

Although there have been increasing reports of a rebounding phenomenon after taking Paxlovid, Ashton said the benefits still outweigh any of the risks.

"What would be the worst-case scenario if President Biden took Paxlovid and got this so-called rebound phenomenon? Just more time being in isolation. The benefits are clear based on the clinical trials of what this drug can do in terms of reducing the risk of hospitalization and death, and that's why it is a straightforward and easy clinical decision to make to give him that medication," she said.

The vice presidenttested positive for COVID-19 in April.Dr. Anthony Fauci,a senior adviser to the president on the pandemic, tested positive last month.
