Britain reported a record 708 daily deaths from COVID-19, including a five-year-old child who is said to be the country's youngest victim.
The Ministry of Health said 4,313 people who tested positive for the virus in the hospital died at 1600 GMT on Friday, while there were 41,903 confirmed cases on Saturday at 0800 GMT, an increase of 3,735.
The number of victims has risen steadily by more than 500 deaths per day this week, and the country is preparing for an expected 10-day high next week.
A total of 637 of the last deaths occurred in England, the National Health Service (NHS) said.
"The patients were between five and 104 years old. 40 of the 637 patients (between 48 and 93 years old) had no known underlying health condition," said a statement.
The NHS said he would not provide further information about the five-year-old patient at the family's request.
A 13-year-old boy from London, Ismail Mohamed Abdulwahab, died last week, days after he tested positive for COVID-19. His family said he had no underlying illnesses.
Minister Michael Gove told a daily meeting that the teenager's mother and siblings were now showing symptoms.
The total death toll now included seven health professionals, he added.
Prime Minister Boris Johnson, who is self-isolating after developing mild symptoms of the disease, ordered a three-week ban on the country on March 23 to try to reduce infections.
However, there were concerns that the warmer weather forecasts for this weekend could seduce people from their homes to green spaces and public parks.
Health Minister Matt Hancock warned of a loosening of social distance and said: "If we do, people will die."
– & # 39; things become a plateau & # 39; –
Imperial College London epidemiologist Neil Ferguson, who advises the government, told BBC Radio on Saturday that a high point was expected on Easter weekend.
"We still believe things will reach a plateau, but we will have a fairly high level of infection for weeks instead of seeing a fairly rapid decline, as seen in China," he said.
But he said it depends on people staying at home. In this case, less stringent measures could be taken "at least until the end of May," he added.
Another record-breaking death toll was announced after 13 residents of a nursing home in Glasgow had died in a week in a suspected coronavirus outbreak.
The Burlington Court Care Home said that those who died had underlying illnesses and two employees were treated for COVID-19.
Coronavirus testing is currently underway in the most serious cases requiring hospitalization, indicating that the true extent of confirmed cases and deaths is underestimated.
The government has now announced that up to 4,000 low-risk prisoners could be released from prison in England and Wales at the end of their prison terms to stop the spread of COVID-19.
A total of 88 prisoners and 15 prison workers tested positive for the virus, and there is concern that it could spread quickly due to shared cells and overcrowding.
The Ministry of Justice announced that the released people would be electronically marked and gradually released under license. High-risk offenders are not considered for early release.
NHS England national medical director Stephen Powis sentenced vandals who attacked new 5G cell towers after discredited claims that they had contributed to the spread of the virus.
Powis called the theory "absolute and complete garbage" and said he was "absolutely outraged (and disgusted") that vital infrastructure had been targeted during a national emergency.
"The reality is that cellular networks are absolutely critical for all of us, especially at a time when we ask people to stay home and not see any relatives and friends.
"But in particular, these are the telephone networks that are used by our emergency services and our health workers," he added.
Later on Saturday, it became known that the British singer and pop icon of the 1960s, Marianne Faithfull, had been taken to a hospital suffering from the virus.
"It is stable and responds to treatment," tweeted music industry publisher Republic Media.
"We wish her all the best and a full and quick recovery."
