The number of people who have tested positive for Covid-19 in the UK stands at 11,658 the Department of Health has said.

A total of 104,866 people were tested with 93,208 negative results as of 9am this morning.

Hospitals in London are being overwhelmed by Covid-19 patients, the head of an organisation representing bosses in the state-run National Health Service has said.

The chief executive of NHS Providers, Chris Hopson, told BBC Radio that London hospitals had seen an "explosion of demand ... in seriously ill patients", likening it to a "continuous tsunami", with numbers predicted to surge in the next fortnight.

"They talk about wave, after wave after wave," he said. "The word that's often used to me is a sort of continuous tsunami."

According to the latest figures, 463 people have died from the virus. London makes up a third of the UK total.

The government is opening a temporary 4,000-bed hospital at an exhibition centre in London next week to treat patients with the virus.

British media reported ten similar facilities could be set up around the country.

Mr Hopson said the problem of dealing with the increased number of patients was exacerbated by the "unprecedented absence rate" of medical staff.

"We're now seeing 30, 40 and even some places 50 percent sickness rates," he said, adding that there was also a "real problem" with ventilator capacity in hospitals.

His comments came as the government announced it had ordered 10,000 emergency ventilators to help tackle the pandemic from billionaire entrepreneur James Dyson.

In an email to staff, the inventor said his company designed the "CoVent" at the request of Prime Minister Boris Johnson, and promised to donate 5,000 to the international relief effort.

Mr Dyson said teams of engineers had been working on the design since receiving the call ten days ago.

"We have received an initial order of 10,000 units from the UK Government, which we will supply on an open-book basis," he said.

"We are also looking at ways of making it available internationally."

The company is now waiting for the design to receive regulatory approval so manufacturing can commence.

Financial aid for self-employed workers

Meanwhile, a financial package aimed at helping self-employed workers get through the coronavirus crisis will be unveiled by UK Chancellor Rishi Sunak today, with the British government under pressure to throw the sector a lifeline.

The move comes after Mr Johnson told parliament he wanted to achieve "parity of support" so the self-employed could have similar levels of protection to waged workers.

As the Commons shut down early for Easter due to the escalating epidemic, the Prime Minister told MPs: "There are particular difficulties with those who are not on PAYE schemes as ... I think the whole house understands.

"We are bringing forward a package to ensure that everybody gets the support that they need."

He added: "I cannot, in all candour, promise the house that we will be able to get through this crisis without any kind of hardship at all.

"We will do whatever we can to support the self-employed, just as we are putting our arms around every single employed person in this country."

Ahead of the Chancellor's announcement, The Daily Telegraph reported one in three self-employed workers were set to ask the government to support their wages.

The move comes after Mr Sunak set out plans for 80% wage subsidies for PAYE employees last week.

The move should affect 1.7 million of the five million self-employed, according to the Daily Telegraph.

Shortages of personal protective equipment (PPE) fuels the health crisis

The move comes as the health crisis continued to dominate national life with the British Medical Association (BMA) warning doctors and patients would die without adequate personal protective equipment (PPE) across the NHS.

The Department of Health said the number of positive coronavirus tests in the UK had risen by almost 1,500.

As of yesterday morning, 9,529 people had tested positive in the UK, up from 8,077 at the same point on Tuesday.

Around 80% of cases of Covid-19 will be a mild to moderate illness.

A total of 97,019 people have been tested with 87,490 negative results.

The rise in UK coronavirus-related deaths from 422 to 465 is a jump of 43.

Ministers are under increasing pressure to step-up testing for coronavirus, especially among health workers.

Prince Charles tested positive for the virus after exhibiting "mild symptoms" and is self isolating in Scotland.

The BMA said there was "growing evidence that thousands of GPs and hospital staff are still not being provided with the kit they need to properly protect themselves and their patients", despite government assurances.

Health Secretary Matt Hancock has said millions of items of PPE had been sent out in recent days, with a hotline set up so staff could report shortages.

BMA council chairman Dr Chaand Nagpaul said: "A construction worker wouldn't be allowed to work without a hard hat and proper boots.

"Even a bee-keeper wouldn't inspect a hive without proper protective clothing.

"And yet this Government expects NHS staff to put themselves at risk of serious illness, or even death, by treating highly infectious Covid-19 patients without wearing proper protection. This is totally unacceptable.

"We are told that lorries are shipping hundreds of boxes of supplies of PPE to GPs and to hospitals, but that isn't the reality for thousands of our members.

"The type of PPE being supplied is not in keeping with World Health Organisation (WHO) recommendations."

Asked about the latest death toll figures, Business Minister Nadhim Zahawi told BBC2's Newsnight: "Well, at this stage I wouldn't interpret anything into the figures.

"I think the Prime Minister is right to say that the message is very clear - stay at home, make sure we protect the NHS and save lives."
