NHS England said the country’s first death occurred on February 28, almost a week before its announcement, according to a report.
The first death was released on March 5, but the date of the woman’s death was not released.
Health trusts in England said six people died in Covid-19 hospitals as early as February – the first death being made public on March 5.
The news came as the UK endured its deadliest day of the coronavirus pandemic, in which 569 deaths were recorded.
The death toll in Scotland has also been underreported due to delays in providing government information on the deaths, Prime Minister Nicola Sturgeon said on Thursday.
Forty deaths at the start of the week were not recorded, which increased the total number of people in the country by 31% in one day.
Sturgeon said authorities were awaiting consent from relatives of the dead before the deaths were recorded.
She added: “Part of the cruelty of this virus is that when people are in the hospital and when they die, family members cannot be with them,” said Sturgeon.
“So it took a little longer for families to be informed and to give their consent to whatever is required.”
Scotland’s health protection later confirmed that it had adopted a “new and more effective” notification system that did not require consent, reports The Guardian.
Scottish Labor Health Spokeswoman Monica Lennon has requested that “full facts” about the virus be available.
This occurs after discrepancies have been spotted in the NHS figures, such as when 159 deaths were reported on March 30, only to have the NHS later change the figure to 401.
