A further 847 coronavirus patients have died across UK hospitals on Friday, with the total now standing at 14,576.
The Department of Health announced that 438,991 people have been tested, this includes those who have been tested more than once.
Those infected with the virus has risen by 21,328 to a total of 108,692 across the UKs four nations.
England reported 738 deaths in hospitals, with the country’s total being 13,134, of these deaths, 138 happened on 16 April, 320 on 15 April with a further 109 on 14 April.
These figures only apply to hospital deaths, those who have died in care homes or in the community are not contained within the figures.
On Thursday the Foreign Secretary Dominic Raab said there will be a further three-week lockdown across the UK.
He also said, there are still “issues with the virus spreading in some hospitals and care homes.”
Professor Costello warned that Britain will most likely have the highest death rate in Europe as the government was “too slow” to act.
He gave evidence to the Commons Health and Social Care Committee on Friday, he said, that the “harsh reality” is “we were too slow with a number of things.”
Professor Costello strongly advised, “If we’re going to suppress the chain of transmission of this virus in the next stage we all hope that the national lockdown and social distancing will bring about a large suppression of the epidemic so far, but we’re going to face further waves.
“And so, we need to make sure that we have a system in place that cannot just do a certain number of tests in the laboratory but has a system at district and community level.”
