US President Donald Trump has spent his first night in a military hospital where he is receiving treatment after testing positive for coronavirus.
“Going well, I think!” Mr Trump tweeted late on Friday. US media say his symptoms include a low-grade fever.
He has so far been treated with an experimental drug cocktail injection and the antiviral medication remdesivir.
In exactly one month, Mr Trump faces Joe Biden in the presidential election.
The president’s diagnosis has upended his campaign and also cast doubt on his attempt to get a new Supreme Court judge confirmed before polling day.
The latest update from Mr Trump’s physician, Sean Conley, in a memorandum late on Friday, read: “I am happy to report the president is doing very well.” He said the president was not in need of supplemental oxygen.
The president, being 74, a man and someone categorised as obese, is in a higher-risk category for Covid-19. The White House said he was flown to hospital “out of an abundance of caution” and would be there for the “next few days”.
