In Miami Beach, police have declared a state of emergency as they struggle to control large crowds of mostly students intent on partying during the Spring Break. An 8pm-6am curfew has been imposed immediately and will last for 72 hours, official said citing an unacceptable level "of chaos and disorder".
Face coverings in future: What have other key experts said?
We earlier highlighted the comments from Dr Mary Ramsay, head of immunisation at Public Health England, that people may need to wear face coverings and socially distance for several years.
She is not the first expert to suggest the basic measures could be in place until other countries successfully roll out jabs.
Survivors of 1972 Andes plane crash call for patience in Covid crisis
Survivors of the famous 1972 Andes plane crash have united in a video campaign calling for Uruguayans to be resilient in the face of the coronavirus crisis.
A Uruguayan rugby team was on board a plane that crashed into the mountain range. When emergency teams couldn't find the wreckage, 29 survivors were forced to hike for days through the snow, with some eventually resorting to cannibalism. After 72 days, the 16 people left alive were rescued. The events were dramatised in the 1993 film Alive.
The Covid-19 campaign, which features 13 survivors, has been shared on social media including by President Luis Lacalle Pou.
“The Andes and the pandemic have a lot in common. The anguish, uncertainty and helplessness is exactly the same as when we crashed on the mountain,” says one.
Another says the questions are the same: "And now, what do we do? How do we get out of this? When is it going to end?"
They urge Uruguayans to be patient and follow Covid restrictions until vaccinations are available for the whole population.
The campaign has been organised by the government as authorities are concerned about rising infection rates.
"A group of Uruguayans can together... survive a mountain range and even control the coronavirus," the survivors conclude.
Venues such as bars and nightclubs may not be able to open as planned if they cannot find enough bouncers to supervise them, a body representing security staff is warning.
The UK Door Security Association (UKDSA) says more than half of positions may not be filled.
After a year of closure many security staff have moved into other work - and some, who are not UK nationals, have returned to their home countries amid Brexit and the pandemic.
New, more rigorous training regulations are due to come in next month, but the UKDSA is calling for them to be postponed - to help agencies recruit new security staff more quickly.
"When we go back on 21 June every operator in our field, every festival, nightclub, bar, restaurant, theatre, every event has been gagging to get back on track - and suddenly everyone is going to say we need security staff," says Stuart Glen, who runs a nightclub in north London.
Having the correct ratio of security staff is a condition of holding a licence to operate, he adds.
"If we can't find the staff then we physically can't open. It's a major issue," Glen says.
The ministry has not specified how many doses have been sold on, but in February South Africa had 1.5 million.
Many African countries have struggled to get their hands on vaccine supplies, though first batches have begun arriving through the global Covax intiative that distributes jabs to poorer countries
"The first batch of vaccines that is being delivered will
benefit nine (African Union) member states and the balance will be collected this
week to be delivered to five other member states," the South African health ministry has said today.
A bit more now from Sir Paul Nurse, speaking earlier on BBC Radio 4's The World This Weekend. The scientist said it was "extraordinary" that the government "is drifting, apparently rather leaderless, into a situation where it seems to be cutting support from science".
“Really it is science that is saving the world from Covid, nobody disagrees with that," said the Nobel laureate, adding the proposed cuts "could be existential" for scientific research.
"Over £1bn cuts just at the time when science is saving the nation. It makes no sense," he says.
"The prime minister and the chancellor have got to realise the danger of the decisions they are making - or rather not making. They still have time to reverse it.
"Our future will depend on science, and it is really being damaged by the decisions they are thinking about.”
The government has said "high-risk, high-reward" scientific research will be funded through the new Aria programme. Aria has £800m funding over four years but the amount it will get is a fraction of the money pumped into existing government research bodies such as UK Research and Innovation.
Town residents urged to get tested amid flare-up

People living in a town in Wales experiencing a Covid flare-up have been urged to get tested for the virus.
Holyhead's infection rate is 466.5 cases per 100,000 people compared to the Wales average of 42.
Anglesey council says mass testing is "a vital step to identify as many positive cases who will be unknowingly infectious and stopping the virus from spreading further" in Holyhead - and Holy Island where the town is located.
Wales-wide restrictions have started to ease - on 13 March the nation's stay-at-home rules were lifted and replaced by a "stay local" message.
People are expected to stick to a five-mile travel rule, and there is flexibility for those in rural areas. But the rise in cases prompted Anglesey council to issue a no travel warning in the area on Friday.
Brazil's Covid 'catastrophe' shows no signs of slowing
Throughout the pandemic, Brazil has rarely escaped the headlines. Infection and mortality rates continue to be sky-high with 2,438 deaths and nearly 80,000 cases recorded on Saturday by the health ministry.
A Nobel Prize winner has called for an immediate investigation into how the first months of the pandemic were handled in the UK.
Sir Paul Nurse, cancer expert and chief executive of the Francis Crick Institute says a full inquiry would "take too long" while we are still in the midst of the crisis.
But he tells Radio 4's The World This Weekend: "I do think we should look at what happened in the first wave of the pandemic, I’m thinking around January to June... The fact that we weren’t prepared as a nation, the slowness in political response - almost casual really - suggesting a failure of scientific and medical advice reaching political power..."
“There are lessons to be learned, and those lessons are important because we are not out of it yet, and, of course, this isn’t going to be the last time that we have to deal with issues like this."
The Indian factory making 6,000 syringes a minute
To vaccinate the global population of nearly 8 billion people, a huge number of syringes will be needed.
Factories like Rajiv Nath's Hindustan Syringes & Medical Devices in India are ramping up production to try to meet demand.
Watch Mr Nath explain how even though his factory is making four million syringes a day, it's still not enough.
Record number of jabs given in England on Saturday
PA MediaCopyright: PA Media
We'e got more vaccination figures - following on from Boris Johnson hailing a record number of jabs given in the UK yesterday, official NHS figures for England show a record 756,873 Covid jabs were recorded on Saturday.
This comes at the end of a week which saw the highest number of vaccine doses delivered since the rollout began.
NHS England said 686,424 first doses were administered yesterday.
Dr Emily Lawson, NHS England's chief commercial officer and senior responsible officer for vaccine rollout, ascribes the "remarkable" figures to "the sustained hard work of NHS staff and all those involved in delivering jabs up and down the country".
"I could not be more proud of all those involved who have helped us to achieve this latest milestone," she says.
NHS chief Sir Simon Stevens says: "The speed and precision of the NHS vaccination campaign has been on full display this weekend.
"Yesterday NHS staff across England administered a remarkable 27 jabs a second. In just one day we vaccinated the equivalent of the entire adult populations of Liverpool, Southampton and Oxford combined."
Official government figures for the whole of the UK are expected within the hour - though as we reported a few minutes ago Boris Johnson says 873,784 were given yesterday.
Another vaccine record set, says PM
Saturday was another record-breaking day for the UK vaccine rollout, the prime minister has announced.
The official data is due to be released in the next hour, but writing on Twitter, Boris Johnson says 873,784 people received a jab yesterday.
A combined 711,156 first and second doses were given to members of the public on Friday.
"A huge thank you to everyone involved and please come forward to get your jab when you are invited to do so," Johnson tweets.
Palestinian authorities begin vaccination campaign
Medical staff and cancer patients in the Palestinian territories will be the first to be vaccinated as authorities announce the start of the nationwide campaign. People in both the West Bank and Gaza will be eligible.
On Saturday President Mahmoud Abbas received the opening jab of the Covid-19 vaccine programme, reported local media.
Last week, 62,000 vaccines doses were delivered to the health minstry from the global Covax initiative that aims to distribute jabs to poorer countries.
A total of 2,656 Palestinians have died of Covid-19 since the start of the pandemic last year, according to the health ministry.
Meanwhile, Israel has so far delivered the world's fastest innoculation campaign.
A critical care nurse who tearfully urged the public to stop panic buying in the first wave of the pandemic last year has said she is considering leaving her profession.
Dawn Bilbrough says the past year has been "relentless, incredibly traumatic and emotionally and physically exhausting".
The 52-year-old, from York, tells BBC Radio 4's The World This Weekend nothing in her 20-year nursing career could have prepared her for the last 12 months.
"There have been times when I've come home and had a good cry, because we have witnessed so much… we're at the patient's bedside 12 hours a day and they haven't had that usual psychological support from their families.
"So we've been there… and got to know them as people, their likes and dislikes, their dreams; and then they've become really unwell and been placed on ventilators and quite often they haven't got through that.
"And that's been difficult because personally I've felt a bond to my patients, and to witness them not progress as we would wish, that's been really hard."
Ms Bilbrough says she and others medical staff needed support for the long-term stress, anxiety and depression those in her profession are experiencing.
"There's just this overwhelming sense of sadness that creeps in… and I think we have to kind of bury that because we're professionals and we can't explore that too deeply when we're at work," she says.
"So we're…carrying it around with us and for me, it's starting to come up a little bit and it needs to be addressed and processed, and it's going to take some time."
We are expecting the latest government figures on Covid to be released in about two hours.
Saturday's data showed there have been nearly 4.3 million confirmed cases of coronavirus in the UK and more than 126,000 people have died. And almost 27 million people have now had their first dose of a coronavirus vaccine.
The average number of new daily cases in the UK has fallen substantially in recent weeks, although the decline does appear to have slowed in recent days.
The number of deaths has also been falling after reaching a peak in January.
Meanwhile, the number of people receiving the vaccine is on the rise.
