The head of the UK's national academy of science has called for everyone to carry a face covering when they leave home in order to tackle coronavirus.

Currently, face coverings are compulsory on public transport in England and Scotland, but advised to be worn elsewhere. From 10 July, masks will be required in shops. In Wales and Northern Ireland coverings are not compulsory.

Prof Sir Venki Ramakrishnan, president of the Royal Society, said the coverings should then be worn "whenever you are in crowded public spaces".

He said evidence shows they protect the wearer and those nearby, and the UK was "way behind" other countries in usage.

No 10 said the use of face masks is always kept "under review".

If you didn't think you'd ever see the Duchess of Cornwall and TikTok in the same sentence, well neither did we.

Camilla - who is married to Prince Charles - has been speaking to Dame Judi Dench about their shared experience of having to use the internet in lockdown to keep in touch with family.

Camilla guest edited The Emma Barnett show for BBC Radio 5 Live today.

Dame Judi told Camilla about her new found fame on TikTok (largely thanks to her grandson) saying: "I love TikTok stardom better than anything."

Parents of school-age children in Wales are still waiting to find out exactly what will happen in the new term in September.

Now Education Minister Kirsty Williams has said any decision on how schools will return will be based on coronavirus transmission rates.

Regular reviews are to be carried out during the summer, she says. She hopes to outline her plan for pupils this week.

Pressure has been growing on the Welsh government to reveal how many schools might return. Read the full story here.

Burundi has launched a mass testing campaign for coronavirus, in a fresh campaign by the new government to fight the spread of the pandemic.

Former president Pierre Nkurunziza was accused of downplaying the issue, saying "God had cleared [coronavirus] from Burundi's skies", almost a fortnight before he died last month of cardiac arrest.

But last week, his successor Evariste Ndayishimiye, declared coronavirus a "major enemy of Burundians" and vowed "to start the fight against that enemy".

At the launch of the campaign in Bujumbura, many people were, unusually, seen wearing masks.

A record 640 tests were taken on the day, the highest number since March when the virus was first reported in the country.

Burundi has so far reported 191 cases from 3,200 tests done in the past three months.

Some of Florida's hospitals are coming under immense pressure with coronavirus patients, with intensive care units at 57 hospitals at full capacity.

According to a report from the state's Agency for Health Care Administration, the hospitals are spread out across 25 of the state's 67 counties. More than 300 hospitals were included in the report, but not all of those have ICUs.

Cases of the virus have surged in US southern states, including in Florida. In the last week, Florida has recorded more than 10,000 new cases in a 24-hour period three times in the last week.

The state's total death toll is now more than 3,800.

We will be hearing from Chancellor Rishi Sunak on Wednesday, as he delivers his summer statement.

Among those particularly interested in what he has to say are some of the young people whose lives have been upended by the coronavirus pandemic.

There could be more than one million young workers who are without a job, if the overall UK level of unemployment goes up from the current 4% of workers to 10%, according to the Resolution Foundation think-tank.

On top of that, under-30s have been hardest hit by a fall in their income during lockdown as more of their money goes on essentials.

So is there anything the chancellor could announce in his speech on Wednesday to help them? BBC Business spoke to some of them to find out.

At least 84 prisoners and nine prison guards and employees have died from the coronavirus so far, according to the Texas Department of Criminal Justice.

The latest victim was Correctional Officer V Kenneth Harbin, 60, who died on 4 July.

According to figures released last week by Texas officials, 8,811 offenders and 1,556 employees have tested positive.

Prisons and jails around the US have been outbreak epicentres since the early days of the pandemic. Inmates have no ability to practice social distancing and sometimes little access to basic hygiene products such as soap and warm water.

In California, San Quentin prison has been hit by a deadly outbreak after infected prisoners were transferred there from another facility.

As of Monday, six San Quentin inmates have died and another 1,387 inmates have tested positive. Officials say they are urgently trying to reduce the prison's population to below 3,000.

We reported earlier that Brazilian President Jair Bolsonaro has tested positive for coronavirus.

Now, footage shows him removing his mask in front of a group of reporters.

Shortly after confirming his test result, he stepped back a few feet and took off the mask. He then told journalists that he looked "fine".

Mr Bolsonaro has consistently downplayed the threat of the virus, and has called it a "little flu".

Dr Mike Ryan, emergencies director for the World Health Organization (WHO), has sent his 'get well soon' wishes to Brazilian President Jair Bolsonaro and said that his infection should serve as an example for others.

"We wish him a speedy and full recovery from this disease," he said on Tuesday. "I think the message to us all is: we are vulnerable to this virus.”

WHO regional director Carissa Etienne echoed his comment while speaking from Washington DC to the directors of the Pan American Health Organization (PAHO).

"This is a pandemic of staggering proportions and we have no option but to continue to put all our energy into controlling it," she warned.

PAHO director for communicable diseases Marcos Espinal added: "The message is that this virus in unpredictable and does not respect race, class or people in power, despite security around any president."

This morning I installed Ireland's just-released contact-tracing app on my phone, where it joined Germany's Corona Warn-App, which was released three weeks ago.

Gibraltar recently released its Beat Covid Gibraltar app, based on the Irish code.

The Republic's Covid Tracker software is also the foundation of an app Northern Ireland is promising to release within weeks. And now there's a hint Wales could go the same way.

"We remain in discussion about a range of options to achieve a working app, including development in Northern Ireland," a Welsh Government spokesman told the BBC.

So when is England finally going to get its app?

The US ambassador to Brazil, who hosted President Jair Bolsonaro at an American Independence Day Party over the weekend, will undergo testing amid news that the Brazilian leader has been infected with Covid-19.

On Saturday, Mr Bolsonaro was photographed by the Brazilian foreign minister embracing US Ambassador Todd Chapman at the 4 July celebration.

After Mr Bolsonaro displayed Covid-19 symptoms on Monday, the US embassy tweeted, external (in Portuguese) that Mr Chapman "has no symptoms, but he is taking precautions".

The US statement added that he will be tested and and will "follow the screening protocols".

The US federal government will pay $1.6bn (£1.3bn) to drug maker Novavax to produce 100m coronavirus doses.

The payment is the largest made so far by the US "Operation Warp Speed" - a partnership between the federal government and the private sector to find a coronavirus vaccine - and the fourth made to a drug manufacturer.

Novavax, which is based in Maryland, has never before brought a product to market, according to the New York Times.

“Adding Novavax’s candidate to Operation Warp Speed’s diverse portfolio of vaccines increases the odds that we will have a safe, effective vaccine as soon as the end of this year,” US Health and Human Services Secretary Alex Azar said in a statement on Tuesday.

Novavax CEO Stanley Erck told CNN on Monday that the deal with the US government "speaks to the confidence that they have in our platform to be able to develop a vaccine". He added that the company aims to ship out 100m vaccination doses by February 2021.

Brazilian President Jair Bolsonaro, who took his fourth coronavirus test on Monday after developing Covid-19 symptoms, has tested positive for the virus.

Mr Bolsonaro has repeatedly played down the risks posed by the virus, calling it "a little flu" and saying that he would not be seriously affected by it.

He has also urged regional governors to ease lockdowns, which he says hurt the economy, and on Monday he watered down regulations on wearing face masks.

As of Monday, the number of deaths in Brazil was over 65,000 and infections were over 1.6m, second only to the United States.

The latest figures from the Department of Health and Social care, external have been released, showing that a further 155 people in the UK have died after testing positive for coronavirus.

It makes the total number of deaths after a positive test in hospitals, care homes and the wider community 44,391.

But it does not include all deaths involving Covid-19 across the UK. That figure is now thought to have passed 55,000.

The DHSC also said that in the 24-hour period up to 9am on Tuesday, there were 581 positive test results. A total of 286,349 cases have been confirmed in all.

No 10 has rejected calls for Boris Johnson to apologise after he said "too many care homes didn't really follow procedures" over coronavirus.

Labour called the PM's comments "crass" and said government advice to care homes had been "conflicting". And one union accused the PM of blaming care workers for government "failings".

But Downing Street said Mr Johnson had been pointing out that not enough was known about the virus in the early stages of the outbreak. The PM's official spokesman added that the care homes had "done a brilliant job under very difficult circumstances" and the government had "put in place rigorous testing and additional funding".

Care homes were hit particularly badly by the coronavirus with nearly 20,000 people confirmed to have died of coronavirus in care homes in England and Wales since the outbreak.

Israel's director of public health has resigned after the country experienced a sharp rise in cases.

Siegal Sadetzki, an epidemiologist, criticised the government's response and said it had lifted lockdown restrictions too quickly.

“The achievements in dealing with the first wave [of infections] were cancelled out by the broad and swift opening of the economy," she wrote in a statement.

Israel imposed a national lockdown in April, and by the following month it had reduced the number of new cases to about 20 a day.

But it reopened schools and businesses shortly after and the rate of infection rose sharply. The daily number of new cases hit 1,000 last week.

On Monday, Prime Minister Benjamin Netanyahu said the country needed to take “limited actions” to avoid another full lockdown.
