WASHINGTON, D.C., USA — President Donald Trump's release from Walter Reed National Military Medical Center and return to the White House make one thing blindingly clear: He is eager to get his battle with COVID-19 behind him, as a reelection campaign clouded by the pandemic draws to a close.
Little else about the president's illness was certain, though. Trump’s doctors and aides were withholding key information on just how sick the president was, what risks lie ahead for Trump under progression of the illness and under treatment by a novel combination of powerful medications, and whether the White House’s aides, security guards, cooks, cleaners and servers from infection by the still-contagious president.
What we know, and what we don’t know:
WHAT WE KNOW:
Trump made clear he is eager to put his three-night stay at Walter Reed behind him, and to play down a pandemic that has killed more than 209,000 Americans. “Feeling really good!” he tweeted. “Don’t be afraid of Covid.”
Disclosures over the weekend that the president’s blood oxygen levels had dropped below normal levels at least twice, and that he was receiving steroid treatment typically used in more serious cases, suggested the president was enduring more than a mild case of COVID-19.
Doctors say that Trump will continue to receive his treatments from the White House. Trump on Friday began a five-day course of remdesivir, a Gilead Sciences drug currently used for moderately and severely ill patients. He received a single dose Friday of an experimental drug from Regeneron Pharmaceuticals Inc. that supplies antibodies to help the immune system fight the virus.
Trump’s also received treatment with the steroid dexamethasone. It has only been proven to help in more serious cases. Among concerns with its use — steroids can tamp down the body’s own ability to fight off infection.
Trump's doctor, Navy Cmdr. Sean Conley, said Monday that Trump “may not entirely be out of the woods yet” but he and the team “agree that all our evaluations and, most importantly, his clinical status support the president’s safe return home, where he’ll be surrounded by world-class medical care.”
Conley said the president could resume his normal schedule once “there is no evidence of live virus still present.”
The Centers for Disease Control and Prevention says those with mild to moderate symptoms — and it's not clear if the president's case falls within that range — should isolate for at least 10 days.
Back at the White House, the ranks grew Monday of infected people in the president’s circle. Press secretary Kayleigh McEnany announced she had tested positive for the virus Monday and was entering quarantine.
The White House says it is doing contact tracing for people who have been at White House events and with Trump and that “appropriate notifications and recommendations are being made.”
Stephanie Grisham, the spokeswoman for first lady Melania Trump, said “all precautions are being taken” to safeguard those serving the ailing Trumps in the White House’s residential quarters, in consultation with the White House’s medical unit.
WHAT WE DON’T KNOW
We don’t know how sick Trump got. We don't know how sick Trump is now.
Conley in daily news briefings at Walter Reed has detailed vital signs like temperature and blood pressure when they are normal, but repeatedly refused to give information that would indicate how serious the president’s respiratory troubles may have been, in particular.
Conley also has failed to explain why Trump is receiving treatment typically reserved for difficult COVID-19 cases.
Trump’s doctors said Monday the president had refused to waive patient-doctor confidentiality to allow them to discuss the results of his lung scans. COVID-19 can cause significant damage to the lungs. Scans reveal signs of pneumonia and other problems.
With treatment still evolving in the pandemic, Trump’s doctors concede they themselves don’t know everything about the interplay of the medications he is taking. “We’re in a bit of uncharted territory,” Conley said.
Conley also refused to detail when Trump last tested negative for COVID-19. That's important for contact tracing of those he might have been in close contact after that time.
The White House also is withholding details on what steps it is taking to stop the spread of the outbreak underway in Trump’s circle. More than a dozen aides, lawmakers and political figures around Trump have confirmed positive tests in recent days.
Officials aren’t saying what measures are being adopted to protect the health of White House staffers — from aides and secretaries to cleaners and valets — around Trump as the infectious president returns home.
And it’s not known if Trump — who long mocked people wearing masks — has committed to abide by any precautions. Trump on Sunday insisted on a drive outside Walter Reed to wave to supporters, heightening risk of infection for those guarding and driving him.
WHAT WE KNOW: HOW TRUMP WAS INFECTED
It's not clear, but attention is focusing on a White House event Sept. 26 introducing Trump’s Supreme Court nominee. Trump gathered more than 150 people in the Rose Garden, where they mingled, hugged and shook hands — overwhelmingly without masks. Photos also show several indoor receptions, where Trump’s nominee, Judge Amy Coney Barrett, her family, senators and others gathered in the close quarters in the White House.
Among those who attended who have now tested positive: former New Jersey Gov. Chris Christie, White House counselor Kellyanne Conway, the president of the University of Notre Dame and at least two Republican lawmakers — Utah Sen. Mike Lee and North Carolina Sen. Thom Tillis.
WHAT WE DON’T KNOW: HOW TRUMP WAS INFECTED
There's no way to know for sure if the Rose Garden event was where Trump — who typically shuns a mask and has kept holding big public gatherings during the pandemic — was exposed. The president had a full week of official and campaign events before his hospitalization Friday.
A third Republican senator, Ron Johnson of Wisconsin, announced his positive test Saturday, and he had not attended Barrett’s nomination kickoff.
The administration says a White House medical team is tracing contacts.
