And here is an overview of some of the biggest coronavirus-related stories from around the world:
We're about to wrap up for the day. Here's what you need to know about coronavirus in the UK today if you're just catching up:
Image source, Mind the GapA social-distancing app that alerts someone when a colleague is too close is being used by Network Rail, which looks after Britain's railways.
Mind The Gap uses audio and Bluetooth signals to detect if users are in close proximity to one another.
It has been piloted at Network Rail, whose staff now use the app widely, and it's being rolled out to other companies.
The technology uses inaudible ultra-high frequency sounds and Bluetooth to calculate the distance between phones, so it does not require an active internet connection to work.
Although many contact-tracing apps have found it hard to accurately detect distances with Bluetooth, Hack Partners, which designed the app, says the combination of the technology with audio measuring, gives an accuracy of between 6-8cm.

Hannah Batchelor runs both a dance academy and a children's party business in the city and she believes both will be affected by the new limit of six people, particularly the party side.
"It is definitely going to have a negative impact on my party business as with the new guidelines I can't really run children's parties.
"It would make such parties effectively illegal gatherings and I don't think that's something parents are going to want.
"That part of my business I won't be able to run for the foreseeable future."

As we reported earlier, a new book has shed light on what US President Donald Trump knew about the coronavirus, and how dangerous it was, as early as February.
A short time ago, White House press secretary Kayleigh McEnany responded to questions about the book. In it, Trump was quoted as saying he wanted to play down the virus to avoid causing panic.
McEnany told reporters that Trump's only motivation in downplaying the dangers had been to reassure the public.
"It's important to express confidence, it's important to express calm," she said. "The president has never lied to the American public on Covid."

Canadian Prime Minister Justin Trudeau has warned against complacency after a spike in coronavirus infections as children returned to school.
"Canadians need to continue to be vigilant," Trudeau said at a media briefing in Toronto. "The last thing that anyone wants is to have to once again shut down our economies and spend our lives to try and counter a massive second wave."
A further 1,606 new infections of coronavirus were confirmed in Canada on Tuesday, bringing the country’s overall tally to 133,748.
Health authorities said the coronavirus reproduction number, which shows how many people someone with Covid-19 is infecting, has risen to just above one, an indication that the virus is spreading.
Up to now, new coronavirus infections have been relatively stable in Canada, hovering at or below the 1,000 cases-a-day mark since the end of May.
The rise in cases comes as schools across the country started to reopen after a nearly five-month forced shutdown.
With the rules for social gatherings in England set to change, here is a refresher of what the guidance is across the UK:
Image source, ReutersEarly in the pandemic, President Trump played down the seriousness of Covid-19
US President Donald Trump was aware in February that the coronavirus was “deadly stuff”, but wanted to publicly downplay the threat of the disease, a new book by American journalist Bob Woodward has revealed.
Trump discussed the seriousness of the disease with Woodward in a series of interviews between December 2019 and July 2020.
On Wednesday several US media outlets, including CNN, external, published excerpts of the interviews, due to be featured in Woodward’s upcoming book Rage.
In one interview on 7 February, Trump admitted the virus was dangerous, airborne, highly contagious and “more deadly than even your strenuous flus”.
“This is deadly stuff,” Trump told Woodward of the coronavirus.
At the time, Trump was casting doubt on the threat posed by the disease, insisting it would disappear soon and was no worse than seasonal flu.
On 19 March, as the US coronavirus crisis began and the White House declared it a national emergency, the president told Woodward: "I wanted to always play it down. I still like playing it down, because I don't want to create a panic."
Trump is yet to comment on Woodward’s book.
Volunteers are to plant hundreds of trees in Berkshire, south-east England, over the coming months to create living memorials to those who died during the pandemic.
Environmentalist Dr Susan Millington said the three new woodlands would become somewhere beautiful for people to relax while coming to terms with their loss.
Residents can also dedicate trees to a loved one, struggling family and friends, or to honour key workers.
During lockdown, councils across England announced plans for green spaces to remember people who have died.

Following a rise in coronavirus cases, the government has announced that social gatherings of more than six people will be illegal in England from Monday.
But there are exemptions - in workplaces and schools, for example.
So where will the new rules apply? Will places of worship be exempt? Can a children's party still happen?
Image source, ReutersThe WHO's Soumya Swaminathan said vaccine safety comes "first and foremost"
Countries cannot start “cutting corners” in the race to develop a vaccine against the coronavirus, the chief scientist of the World Health Organization (WHO) has said.
A vaccine is considered vital in building widespread immunity to the coronavirus, which would allow restrictions on life to be lifted.
But there are fears that vaccine developers worldwide are moving too fast, and in doing so, compromising the safety and efficiency of the product.
"Just because we talk about speed and scale doesn't mean we start compromising or cutting corners on what would normally be assessed," the WHO's Dr Soumya Swaminathan said on Wednesday.
"The process still has to follow through rules of the game. For drugs and vaccines which are given to people, you have to test their safety, first and foremost," she said.
Dr Swaminathan issued the plea after the trial of a leading candidate for a vaccine developed by AstraZeneca and Oxford University was paused due to concerns over side effects. AstraZeneca described it as a "routine" pause.
Western experts have also raised concerns about the safety of Russia's fast-track vaccine, which entered its third phase of trials on Wednesday.

Image source, EPAMore than 200 vaccines are in development worldwide
During the press conference, Sir Patrick Vallance said progress on a vaccine which protects people against the virus is going well.
More than 200 vaccines are being developed around the world and a small number are already in final phase-three trials.
It is inevitable that some people taking part in these trials may have side effects, which need to be investigated. Clinical trials are paused all the time. The trial of a vaccine developed by AstraZeneca and Oxford University was paused on Tuesday.
But this isn't necessarily bad news.
The safety of a potential vaccine is paramount. The more time that's taken to research its effects in different groups of people of different ages, the more effective the vaccine will be in the long run.
Vallance also appealed for people to volunteer to take part in clinical trials if they were eligible.
Reality Check
The prime minister said: "To date, we’ve carried out 15.4 million antigen tests. That’s more than any other country in Europe and more per head than other European countries like Germany and Spain."
The overall figure for tests to detect the presence of coronavirus in the body was 16.07 million up to 2 September. , external
That is the number of tests, not the number of people tested, and the figure includes 1.4 million surveillance tests. These are done not on people showing symptoms, but as part of a survey to estimate how many people in the whole population have the disease.
This total is higher than the number of tests carried out in any other European country. But obviously there are huge differences in size of population between those countries.
The Our World in Data website , externalcompares the number of tests per 1,000 people across the world. It does not count surveillance tests.
The UK, with 215.85 tests per 1,000 people, is one of the top countries in Europe, but Luxembourg and Lithuania have performed more tests so far, with 636.42 and 248.54 tests per 1,000 respectively. Germany carried out 147.8 tests per 1,000 people, and Spain 150.6.

During his press conference, Boris Johnson made a direct appeal to students to observe the new rules when their terms start.
He said opening universities was critical for the life chances of young people.
But he acknowledged students were in the age bracket with the highest rate of infections at the moment.
He also appealed to universities not to send students home in the event of a Covid-19 outbreak.
This was so the virus is not spread unnecessarily around the country, he said.
Johnson said: “My message to student is simple - please, for the sake of your education and your parents’ and your grandparents’ health: wash you hands, cover your face, make space, and don’t socially gather in groups of more than six, now and when term starts.”
He also confirmed the Department for Education was due to publish guidance on how universities could re-open safely shortly.
The UK Labour Party leader, Sir Keir Starmer, says he supports the new measures introduced by the government in England.
But he says the government has acknowledged there was a problem in its communications of the earlier rules, and "that has got to be fixed".
Starmer adds: "[The government] also needs to recognise the testing regime is all over the place at the moment. They can't pretend there isn't a problem, so that needs fixing as well."
A further eight people have died in the UK within 28 days of testing positive for Covid-19, bringing the total number to 41,594. Overall, daily deaths in the UK remain low.
But the number of confirmed cases is rising. The latest official figures show that as of 09:00 BST, there had been a further 2,659 lab-confirmed cases of coronavirus - bringing the total to 355,219.
UK Prime Minister Boris Johnson has just finished his press conference on coronavirus.
So, what did he and his scientific advisers, Chris Whitty and Patrick Vallance, say?
Nick Eardley
Political correspondent
That press conference can be broken into two parts.
The first is the sombre message - that the virus is increasing again and new restrictions must be brought in for England.
For many people, the limit on social gatherings will be significant and potentially upsetting.
The introduction of nationwide measures is a big deal and something ministers wanted to avoid.
They’re doing it because they’re worried.
At the same time, the PM wanted to inject some optimism.
Boris Johnson is hoping mass tests - maybe daily - could allow people to leave the house in the morning knowing if they are transmitting the virus or not.
That would be a game changer.
But there are significant issues with the testing programme at the moment, and it is far from guaranteed, as the scientists made clear.
Image source, ReutersJohnson said "we will beat the current outbreak"
Johnson concludes the press conference by saying it has been a "dose of realism and common sense".
But the PM says: "I remain ambitious about the programme and that a lot of progress can be made in a short time".
He reiterates his message, saying: "It is very simple - it remains hands, face, make space and get a test if you have symptoms.
"But also to observe and enforce that rule of six [on gatherings].
"That's the way I think we will beat the current outbreak."
We will be bringing you a round-up of the briefing and more analysis soon so do stay with us.
