The president had already tested positive Thursday when he appeared on Fox News.
President Donald Trump's condition is continuing to improve as he fights a coronavirus infection, doctors say, and he may be able to leave Walter Reed Medical Center as early as Monday -- even as details emerge that the president allegedly initially tested positive for COVID-19 earlier than he acknowledged.
Doctors also reported that Trump, over the course of exhibiting coronavirus symptoms, had earlier experienced two episodes of "transient drops" in his oxygen saturation.
Yet the president was feeling well enough Sunday evening to briefly leave Walter Reed for a surprise drive-by, waving to supporters outside the hospital.
Meanwhile, numerous questions remain about how many people at the highest levels of government had been exposed to the virus after a week of events involving the president where social distancing and mask-wearing were lax in the White House and elsewhere.
Dr. Sean Conley and the medical team were asked about videos that showed President Trump not wearing a mask while updating the public on his current condition.
Conley told reporters on Sunday that the president "wears a mask anytime he's around us" and that all hospital officials are wearing their N95 masks and full personal protective equipment.
Dr. Garibaldi, part of the medical team treating President Trump, said if the president continues to look and feel as well as he does Sunday, the hope is he can be discharged as early as Monday to return to the White House where he can continue his treatment.
Trump's medical team said the president has remained without a fever since Friday morning and his vital signs are stable. He is not complaining of any shortness of breath or other significant respiratory symptoms.
Trump is walking around the White House medical unit at Walter Reed without any limitation or disability.
Doctors continue to monitor cardiac, liver and kidney function, which continue to show normal findings.
Dr. Conley said over the course of exhibiting coronavirus symptoms, President Trump has experienced two episodes of "transient drops" in his oxygen saturation.
The medical team decided to administer the steroid dexamethasone based on the timeline from the initial diagnosis and concerns over "possible rapid progression of the illness."
"Thursday night into Friday morning when I left the bedside the president was doing well, with only mild symptoms and his oxygen was in the high 90s," Conley said. "Late Friday morning, when I returned to the bedside, the president had a high fever and his oxygen saturation was transiently dipping below 94%. Given these two developments, I was concerned for possible rapid progression of the illness"
