Donald Trump returned to the White House after three nights in hospital treated with COVID-19.
Shortly after his return, the US president released two videos – one with photos of his trip accompanied by hot orchestral music, the other talking on the balcony accompanied by US flags.
Mr Trump has told Americans to “get out” and “don’t be afraid” of the coronavirus, even though more than 210,000 citizens have died from the disease and about 7.5 million have been confirmed infected.
“We’ll go back to work, we’ll be ahead. As your leader I should have done that. I stood in front. I led. No leader can do what I did. I know there is danger, there is danger, but that’s okay. physically, I don’t know. “
Responding to Mr. Trump’s comments, Dr. David Nace of the University of Pittsburgh Medical Center said COVID-19 was still “absolutely dangerous” and Dr. Sadiya Khan of Northwestern University Feinberg School of Medicine added: “I would not say Mr. Trump’s words) could reduce or increase spread. “
The 74-year-old president has also promised that the antiretroviral drugs “are all approved” and that vaccines are “temporary”. He did not provide further details but the vaccine is expected to be widely available until next year.
Earlier, Mr Trump had wandered off when he walked out of the gold doors at Walter Reed Medical Center in Maryland after his three-night stay.
He was flown by President Marine One in a helicopter back to the White House, where he flew the stairs of South Portico, removed his mask and searched for photographs.
Sometimes his breath seemed to work and his mask stayed in his pocket as he went inside.
Mr Trump was admitted to hospital on Friday and his doctor Sean Conley said he had received twice as much oxygen since his diagnosis, something he had previously denied.
Mr Trump had not had a fever for more than 72 hours and his oxygen levels were normal, his medical team said Monday. They did not say when she was last diagnosed with the virus.
Dexamethasone is a steroid commonly used in critically ill patients and remdesivir is an antiretroviral drug given to Mr. Trump within five days.
He will continue to receive medical assistance from the White House but it is not yet clear how he will handle his re-election campaign ahead of the November 3 vote.
Meanwhile, Mr Trump’s press secretary Kayleigh McEnany is the latest White House employee to find out she is infected, along with other media office staff.
