Trump's medical team is "extremely happy with the progress the president has made", says his personal doctor, Dr Sean Conley.

He was brought into hospital as a "precautionary measure", Dr Conley says.

The medical team say President Trump is not on oxygen or having difficulty breathing,

One of the doctors says Trump told him: "I feel like I could walk out of here today."

He has been fever-free for over 24 hours, the doctors say.

President Donald Trump is doing "very well" after spending the night in a hospital, his physician Dr Sean Conley has said.

We're still waiting for Donald Trump's personal doctor to give an update on his health.

It's unclear exactly how the president caught the virus, but scientists say it is best for people to maintain physical distance and to wear a face covering over their noses and mouths.

Making sure you're wearing a mask - and doing it right - is key, as BBC health correspondent Laura Foster explains.

Trump's Democratic opponent, Joe Biden, and Biden's running-mate, Kamala Harris, said on Friday they had both tested negative for Covid-19. Both wished Trump and his wife Melania well.

The Democratic campaign has moved to take down all its negative ads regarding Trump temporarily, but election campaigning has continued. Harris addressed a mobilisation drive-in event in Las Vegas, Nevada, overnight, while Biden campaigned in Grand Rapids, Michigan, earlier on Friday.

CBS reports that Biden campaign manager Jen O'Malley Dillon has emailed campaign staffers across the country to reassure them that precautions will be taken with Biden, 77, and Harris, 55, travelling.

The next key event for the race falls on Thursday when Harris is due to debate Trump's running-mate, Vice-President Mike Pence, in Salt Lake City, Utah.

It's no surprise that "Trump coronavirus" queries dominated online searches across the US on Friday.

According to Google Trends,, external the interest peaked at 14:44 GMT (10:44 EST) on Friday (on the chart above 100 = popularity peak), but the phrase continues to be one of the most searched queries today.

The top five most-searched items in the past day were all associated either with "Trump", "coronavirus", "update", "cases" or "US".

With Trump's doctors due to give an update shortly, a well-known US cardiologist has weighed in with a few questions about his condition and treatment.

Jonathan Reiner is the longtime cardiologist to Bush-era Vice-President Dick Cheney, and co-authored a book with him about his heart condition.

His questions for Dr Sean Conley include wanting to know when the president last tested negative for Covid-19, and why an experimental drug was administered in the White House and not in the hospital, where more monitoring facilities were available.

Dr Reiner has previously speculated about Trump's health. In 2019 he told US media he was sceptical that a visit to the Walter Reed military hospital - where the president is currently being treated - could be described as "routine", which was the White House characterisation of the visit.

The president's physician Dr Sean Conley is due to give an update from the Walter Reed military hospital where he is being treated at 11:00 Eastern Time (16:00 BST) - or any minute now.

It will be the first public update since Friday evening, when Dr Conley said "the president is doing very well".

A tweet by Biden's wife Jill today contains just two words: "One month".

It is indeed just a month until election day on 3 November, but Americans don't have to wait until then to cast their ballots: depending on which state they live in, early voting has been under way since 4 September, as an Associated Press guide, external explains.

In the 2016 presidential election, nearly one quarter of votes were cast by post, external, and that number is expected to rise this time around due to public health concerns over coronavirus.

Of course, postal voting this year has been something of a red flag for Trump, who controversially suggested that it encouraged fraud.

Ellen Weintraub, commissioner of the Federal Election Commission, said of the issue: "There's simply no basis for the conspiracy theory that voting by mail causes fraud."

The president's physician Dr Sean Conley is due to give an update on Trump's condition from the Walter Reed military hospital where he is being treated at 11:00 Eastern Time (16:00 BST), according to US media.

There has been little news on how he is since Friday evening, when Dr Conley said in a memorandum that he was "happy to report the president is doing very well" and was not in need of supplemental oxygen.

Mr Trump tweeted "going well, I think!" after his arrival at Walter Reed. 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, after both he and First Lady Melania Trump tested positive for Covid-19.

With the presidential election just weeks away, Trump's condition throws up a host of questions about what this could mean for campaign events, the election, and whether power would need to be transferred if he becomes incapacitated.

Joe Biden, Donald Trump's rival for the presidency, has urged Americans to "do their part" and wear masks to protect themselves and those around them from Covid-19.

His intervention comes as the president is in hospital with the virus, and a growing number of people in his inner circle have also tested positive.

President Trump's eldest son Don Jr has shared his thanks with supporters, a day after his father and First Lady Melania confirmed they had Covid-19.

Donald Jr says he has tested negative for the virus. His siblings Eric and Ivanka also reported negative tests.

The younger Mr Trump added that "even yesterday" his father was "working hard for the American people".

As America comes to terms with the president having coronavirus just a month before election day, we asked some older voters with a range of political views how they reacted when they heard the news.

Republican Senator Ron Johnson has tested positive for Covid-19 but appears to be an asymptomatic case, his spokesperson says.

The Wisconsin senator, who heads the Senate Homeland Security and Governmental Affairs Committee, had the result confirmed on Friday.

He "feels healthy and is not experiencing symptoms" but will stay in isolation until he is cleared by a doctor, the spokesperson said.

They did not indicate how Sen Johnson might have caught the virus. Wisconsin news provider Wkow 27 quoted his office as saying he had become infected shortly after returning to Washington on 29 September, following two weeks of self-isolation during which he had twice tested negative.

Sen Johnson becomes the third Republican senator to test positive in the past two days - in addition to Thom Tillis and Mike Lee - along with others including former Trump aide Kellyanne Conway, Trump campaign manager Bill Stepien, Republican National Committee (RNC) Chairwoman Ronna McDaniel, and three White House correspondents.

Since the pandemic began, what was once highly normal behaviour has become anything but. Hugging is off-limits; masks are commonplace.

This video from last Saturday's event in the White House Rose Garden could have been filmed in September 2019, rather than 2020. In it, Republican Senator Mike Lee is seen shaking hands, touching people on the arm and dispensing hugs.

He's now tested positive for the coronavirus - one of seven people who were there to do so, at this point.

After the US president announced he and his wife had tested positive for Covid-19, Twitter warned users , externalthat tweets which "wish or hope for death, serious bodily harm or fatal disease against *anyone* are not allowed".

Such tweets would "need to be removed", it said, explaining its policy on abusive behaviour, but it added that posting them would not automatically mean suspension from the platform.

Some users have accused Twitter of not taking similar abuse as seriously when it is directed at other people, however.

Before he fell ill, Donald Trump was hoping to seat Judge Amy Coney Barrett on the US Supreme Court to fill the place left vacant by the death of Ruth Bader Ginsburg. The timetable was already tight: the presidential election is on 3 November.

But now, several of those who were at the Rose Garden event last Saturday to unveil Judge Barrett's nomination have been infected with the coronavirus. They include two key Republican senators, Mike Lee and Thom Tillis, who both serve on the judiciary committee which is scheduled to begin hearings on 12 October. Senator Tillis has said he's self-isolating for 10 days.

However, even if the nomination process is delayed until after the election, it could be completed in the so-called "lame duck" session of Congress - before January, when the new session begins. With a third of the Senate up for re-election, including some vulnerable Republican seats, this could affect the vote.

The basic precautions against the coronavirus include wearing a mask, washing hands, and keeping a safe distance from other people. Even after Trump fell ill, not all White House officials were wearing masks in public. Here's Chief of Staff Mark Meadows defending his stance to reporters on Friday:

Coronavirus is continuing its spread across the world, with more than 34 million confirmed cases in 188 countries and more than one million deaths.

The virus is surging in many regions, and some countries that had apparent success in suppressing initial outbreaks are seeing infections rise again.

New cases have risen over the last few months in several regions and the World Health Organization (WHO) has warned the global death toll could hit two million before an effective vaccine is widely in use.

As well as an experimental antibody treatment, President Trump is also being treated with the drug remdesivir. But what is it, and how well does it work?

Remdesivir is an anti-viral medicine developed by Gilead Sciences. It has previously been used to treat cases of the Ebola virus.

It's undergoing clinical trials for the treatment of Covid-19 in several countries, including the Recovery trial in the UK, thought to be the world's largest study of potential coronavirus treatments.

Early data suggests it can cut recovery time by about four days, external, but there is no evidence yet that it can save lives.

Dr Anthony Fauci, the leading US expert on infectious diseases, said a US trial showed the drug has a "clear-cut, significant, positive effect" in reducing the time needed to recover from the coronavirus.

Regulators in the UK, US and Japan have made urgent arrangements to make it available to some patients.

Donald Trump has clear risk factors - including his age, weight and being male - that all raise the chances of a severe coronavirus infection.

He is 74 and has a Body Mass Index (BMI) over 30, which is the clinical definition of obesity.

At this point, Mr Trump has only "mild symptoms" and is being treated with drugs that slow the virus's assault on the body.

But age is a clear and strong link to developing a severe infection, leading to hospital treatment and in some cases death.

"But most people who get an infection also get better," Dr Bharat Pankhania, from the University of Exeter medical school told the BBC.

An early analysis of more than 100 studies, external, taking in data from around the world, showed the risk for children and young adults was tiny.

However, at age 75 it is estimated that one in 25 people who catch coronavirus dies. This rises to one in seven people aged over 85 and one in four over the age of 90.

A similar pattern has been seen by the US Centers for Disease Control (CDC).
