NHS England revealed that from the 260 more people in the UK, 13 were not elderly or vulnerable
More than a dozen of those who died of coronavirus most recently did not have underlying health issues.
Yesterday it was revealed a further 260 people had died from coronavirus in the UK, all between the ages of 33 and 100 years old, marking the country’s worst day yet.
But 13 of those who died had no underlying health issues, NHS England has said.

Those who died that did not have pre-existing conditions were between the ages of 63 and 99 years of age, the organisation said in a statement yesterday.
The latest figures released show that 1,019 people have died from the virus since it started spreading in the UK.
The announcement comes as NHS bosses said keeping coronavirus deaths in the UK below 20,000 would be "a good result".
Speaking at a press conference on Saturday afternoon, Professor Stephen Powis, National Medical Director of NHS England, said: "The number of deaths that arise out of this epidemic in the UK, if it’s less than 20,000 as Sir Patrick Vallance said, that would be a good result, although every death is absolutely a tragedy
“But we shouldn’t be complacent about that, although that would be a good result, it will only happen if we stop the transmission of the virus.”

A total of 120,776 coronavirus tests have taken place, with 17,089 positive results and 103,687 people testing negative.
There has been a slight improvement in the daily rate of new cases, with a further 2,510 patients diagnosed with the virus yesterday, a drop of 411 from the 2,921 new patients diagnosed the day before.
Prof Powis continued: "It is early at the moment and the scientists who are working with the government to model what we can expect are of course adjusting their predictions now as we start to see the actuality of the epidemic in the UK, rather than what we believed might have happened a few weeks ago."
The British government is "very concerned" following the latest figures, senior minister Michael Gove said on Sunday.
"Naturally we are very concerned and our thoughts and prayers are with the families of all those who have lost loved-ones in the last few days," he told Sky News.

Labour MP Dr Rosena Allin-Khan has warned that no single group of people are immune from coronavirus
She said: "We were hearing so often that it only really affects people over 70, it only really affects people that have underlying health conditions, and that's why I asked the Prime Minister in ( PMQs ) - why are the social distancing measures merely just suggestions?
"Because what we were seeing echoed on the NHS frontline was the fact that people were coming in who were young, fit and healthy.
"Of course, the majority of the patients will be older, those that actually require ventilation, but no single group of people are immune.
Governmental advisers warn that even stricter social distancing measures could be put in place if the increase in figures doesn't stop.
