This was the scene in Tesco Llansamlet store in Swansea this morning when NHS workers were allowed in early to do their shopping.

All McDonald's restaurants across the UK and Ireland will close by 19:00 GMT on Monday 23 March.

The fast food giant said the decision was "not taken lightly" and was made "with the well-being and safety of our employees in mind, as well as in the best interests of our customers".

Cardiff Council is shutting a car park to the public to provide spaces for doctors, nurses and other NHS staff.

Signs are going up in Heath Park saying the spaces can only be used by staff at the nearby University Hospital of Wales.

Council leader Huw Thomas said: “These are unprecedented times and we want to do everything we can to help our colleagues in the NHS.

"We hope this will make things just a little easier for NHS staff who are doing a remarkable job trying to keep us all safe from this virus.”

The Federation of Small Businesses (FSB) has called on Boris Johnson to quickly deliver his new support measures for the 5,000,000 self-employed people around the UK.

FSB national chairman Mike Cherry said: “These are people who have worked hard to build up their businesses, paid their taxes and helped the economy to grow.

"They now face a crunch point, with many unable to operate – leaving them without money, but with bills still stacking up.

“We have been strongly urging the government not to allow the self-employed to be left high and dry, and it is welcome to hear the that the Prime Minister is listening and offering new hope.

"This must now be turned urgently into practical and easily accessible support. Time is now running out."

South Wales Police has added to the warning about false information by asking people only to take note of official sources and not share rumours which circulate on social media.

Grass fires were started in Caerau, Maesteg, earlier today, which has drawn criticism from South Wales Fire and Rescue Service's chief fire officer

Staff at Cwm Taf Morgannwg health board have been warned about posts on social media purporting to be from management. It seems false information is being handed out.

Adding to the voices urging people not to treat these sunny days as normal days during the coronavirus pandemic, it's the Welsh Local Government Association.

In Ceredigion, the council has thanked the caravan and campsites which have closed following a "high influx" of visitors to the area.

In a statement, it said: "We are aware that this will be a difficult decision for business owners.

"However, it’s the right decision given that people staying at home in their own areas will help reduce the spread of the virus and save lives."

We heard on Saturday from the leader of Anglesey council, who asked vistors to stay away during the coronavirus outbreak.

Now the council says it's closing car parks, nature reserves and country parks on the island.

The economic development member Carwyn Jones said: "These are tough measures but it's essential we take them.

"We must act and stop visitors coming to the island with immediate effect." he said.

"I am also urging local tourism and hospitality providers to close their premises to prevent the spread of coronavirus and help protect public health."

We've been talking about social distancing, so here's a reminder of what that means from the BBC's health reporter Laura Foster.

From tomorrow until the end of April, Transport for Wales has announced there will be free travel for NHS workers.

A spokesman added: “We are doing all we can to keep vital services running, so that emergency service staff who are using our trains and key workers are to travel in safety with confidence.”

A Welsh Government campaign on how to help people who are staying at home because of coronavirus has been launched.

First Minister Mark Drakeford said: “I’ve seen so many good things happening, from online choir groups to grocery deliveries, as people across Wales go out of their way to help others with their everyday needs.

“Communities have pulled together to support neighbours in this time of need. Today, we’re asking others to follow the shining example by doing their bit if they’re able to.”

Earlier, First Minister Mark Drakeford said that letters are being sent to 70,000 of Wales' "most vulnerable people" advising them to stay indoors for 12 to 16 weeks.

In his press briefing Prime Minister Boris Johnson said that such "shielding" measures - which will apply to around 1.5 million vulnerable people in England - will do more than many other measures to reduce the number of coronavirus cases in the UK.

On social distancing, Mr Johnson said that, while he wants people to enjoy outdoor spaces, people must follow the advice.

"Don't think that fresh air in itself provides some sort of immunity," he says.

Homemade signs have been popping up across various parts of Wales.

Here's one from Cemmaes Road in Powys.

And another from Llithfaen in Gwynedd

Carmarthenshire was one of the areas urging people to stay away but the council is going one step further by closing parks, external.

All council-run parks including Pembrey Country Park, Llyn Llech Owain, Mynydd Mawr Woodland Park and Parc Howard will shut from 18:00 GMT.

Rhondda Cynon Taf council is closing play areas.

Earlier, Monmouthshire council's chief executive said the road leading to the Sugar Loaf mountain would be closed if people ignored calls to stay away. Now the police have closed it.

The chief executive of the Welsh Ambulance Service, Jason Killens, has thanked a member of his team, Ieuan Healan, who has tweeted about his experience at work.

Mr Killens said: "I know it is really tough right now and our people are anxious, tired and working very hard.

"I’m immensely proud of you and all our Welsh Ambulance Service people right now doing what is both necessary and right for our patients."

He also encouraged people to stay at home and save lives.

So what should you do if you go for a walk in a park and it is crowded?

Prof Robert Dingwall, a sociologist from Nottingham Trent University who is advising the UK government, said problems occur when people cannot maintain the recommended two metre (6ft) separation.

He says: "If that is the case, then it probably is better to go home and pick a quieter time or a quieter location."

Dr Robin Thompson, an epidemiologist at Oxford University, added: "The key thing is to exercise while minimising contacts.

"There are many walks all across the UK - so, where possible, individuals can research walks without main attractions such as viewpoints or other areas that represent likely gathering points for groups of people."

"Local footpaths are likely to be less crowded than walks through major parks. And we can all try and maintain at least two metres distance between ourselves and others while out exercising."
