President Trump returned to the White House on Oct. 5, walking up the steps of the South Portico and removing his mask to pose for photos, after three days of hospitalization for Covid-19.
Mr. Trump’s physician, Dr. Sean P. Conley, said on Oct. 5 that the president’s health had improved after three days of treatment at Walter Reed National Military Medical Center and that he would return to the White House. The announcement came after doctors and senior White House staff members had given conflicting updates about the president’s condition, treatments and when he learned he was infected with the coronavirus.
A timeline of events about the president’s illness is drawn from his tweets, news conferences, statements from the White House and reporting from The New York Times.
Mr. Trump and his team traveled to Minnesota for a rally that lasted about 45 minutes — about half the length of his typical campaign speeches.
During the event, one of Mr. Trump’s closest advisers, Hope Hicks, started to have symptoms related to the virus.
On the return trip, Mr. Trump slept as some of his advisers spoke about the condition of Ms. Hicks, who was isolated in the back of the plane.
At the event, Mr. Trump appeared before hundreds of supporters, both indoors and outdoors. One person who saw the president there said he was in contact with about 100 people and appeared lethargic.
On a call with Iowa voters and in an interview with Sean Hannity on Fox News, Mr. Trump sounded raspy.
Later that night, Mr. Trump and the first lady, Melania Trump, tested positive for the coronavirus, officials said.
The president had a mild cough, nasal congestion and fatigue.
Close to 1 a.m., Mr. Trump said on Twitter that he and the first lady had tested positive for the coronavirus.
The doctor recommended that Mr. Trump be given supplemental oxygen.
“He was fairly adamant that he didn’t need it,” Dr. Conley said. “He was not short of breath. He was tired, had the fever, but that was about it.”
After about a minute on two liters of supplemental oxygen, Mr. Trump’s saturation levels were back over 95 percent, Dr. Conley said. The president stayed on the supplemental oxygen for about an hour at the White House.
That evening, Mr. Trump was taken to Walter Reed National Military Medical Center for a more thorough evaluation and monitoring.
Mr. Trump received an 8-gram dose of an experimental polyclonal antibody cocktail. He also took zinc, vitamin D, famotidine, melatonin and aspirin.
The president also was given his first dose of remdesivir, an antiviral drug that has an emergency approval from the Food and Drug Administration as a Covid-19 therapy.
Mr. Trump has mild heart disease, similar to many men in their 70s. He also takes a statin drug to treat high cholesterol and aspirin to prevent heart attacks. His health summary, released in June, showed that he crossed the line into obesity at 244 pounds.
The president’s blood oxygen level dropped for a second time, to about 93 percent, which some experts describe as a potential indicator of severe Covid-19, though it was unclear if the president received any supplemental oxygen.
He was given the steroid dexamethasone, which has been used to treat diseases like lupus, arthritis and cancer. A study conducted by scientists at the University of Oxford showed the drug reduced deaths of Covid-19 patients on oxygen by one-fifth.
Mr. Trump was given a second dose of remdesivir and did not exhibit any known side effects, doctors said.
Dr. Conley said that, as of that night, Mr. Trump remained “fever-free and off supplemental oxygen.”
“While not yet out of the woods, the team remains cautiously optimistic,” he added.
“The president’s vitals over the last 24 hours were very concerning, and the next 48 hours will be…
