New figures have shed more light on which groups are extremely vulnerable to coronavirus and where the bulk of the deaths are occurring in the UK.
Data released by the Office for National Statistics revealed 38 deaths in a single week that were previously unreported because they occurred outside hospitals.
The figures suggest one in 14 coronavirus-related deaths in England and Wales could be taking place outside hospitals and the overall toll is much greater than thought.
Covid-19 was linked to five per cent of deaths in the week up to March 27.
The report was released as the Department of Health's official coronavirus death toll, which only accounts for in-hospital deaths since the outbreak began, was set to surpass 5,400 on Tuesday.

The true total is likely to be several hundred higher due to deaths in private homes, care homes, hospices or other places.
A total of 1,639 deaths in England and Wales that occurred up to March 27 (and which were registered up to April 1) involved Covid-19, according to the ONS.
Of these deaths, 1,568 were in England.
This compares with 1,649 deaths reported by NHS England for the same period, the ONS said.
What groups have been worst affected?
Separate figures from the ONS show that of the 647 deaths involving Covid-19 registered in England and Wales up to March 27, 233 (or 36 per cent) were people aged 85.
A further 215 (33 per cent) were people aged 75-84.
A total of 120 deaths (19 per cent) were people aged 65-74.
Seventy (11 per cent) were people aged 45-64.
Nine deaths (one per cent) were aged 15-44 years.
Where are people dying from coronavirus?
The highest number of deaths was recorded in London, while the lowest number was in the East and Yorkshire and the Humber, the ONS said.
For the week ending March 27:
South East: 69
West Midlands: 67
North West: 60
East Midlands: 24
South West: 19
North East: 15
Yorkshire and the Humber: 12
Separate figures from Public Health England, which are broken down by NHS region, show that London has recorded the most confirmed cases (12,636), as of 9am on Monday.
It is followed by the Midlands (7,385), the North West (5,549), and the North East and Yorkshire (5,422).
The South East has recorded 4,897 cases, followed by the East (3,402) and the South West (1,976).
How many people are dying at home?
The ONS report revealed 38 deaths (in the week up to March 27) that were not included in the Department of Health's official tally because they occurred outside hospitals.
Of those, 15 occurred in private homes and 20 were in care homes.
Two were in hospices.
One was listed as "elsewhere" with no further information.
It means that seven per cent of Covid-19 deaths that week occurred outside hospital.
Overall, just under five per cent of all deaths registered in the week up to March 27 mentioned "novel coronavirus (Covid-19)".
More men dying than women
More men are dying than women in all age categories, the statistics show.
The largest difference was in age group 75 to 84 years where there were 138 deaths involving coronavirus in males and 77 in females, the ONS said.
Here is a breakdown:
Under 1 year - Males: 0. Females: 0.
1 to 14 - Males: 0. Females: 0.
15 to 44 - Males: 6. Females: 3.
45 to 64 - Males: 44. Females: 26.
65 to 74 - Males: 81. Females: 39.
75 to 84 - Males: 138. Females: 77.
Over 85 - Males: 128. Females 105.
Is the overall death rate higher than it was in previous years?
The ONS wrote in its report: "The provisional number of deaths registered in England and Wales in Week 13 (week ending 27 March 2020) increased from 10,645 in Week 12 (week ending 20 March 2020) to 11,141.
"This is 1,011 more deaths than the five-year average of 10,130.
"The number of deaths mentioning 'Influenza or pneumonia' on the death certificate increased from 1,841 in Week 12 to 2,090 in Week 13.
"In Week 13, 18.8% of all deaths mentioned 'Influenza or Pneumonia', Covid-19, or both.
"In comparison, for the five-year average, 19.6% of deaths mentioned 'Influenza and Pneumonia'.
"'Influenza and Pneumonia' has been included for comparison, as a well-understood cause of death involving respiratory infection that is likely to have somewhat similar risk factors to COVID-19."
What age was the youngest person to die from coronavirus in the UK?
A five-year-old child became the youngest person to die in the UK and in Europe after contracting coronavirus.
The child, whose death was announced on Saturday, had underlying health conditions, said Cabinet Office Minister Michael Gove.
Other recent victims include 13-year-old Ismail Mohamed Abdulwahab, from Brixton, south London, and 19-year-old Italian chef Luca Di Nicola, who also lived in the capital.
Both had no known underlying health conditions.
The difference between the coronavirus death figures published by the Office for National Statistics and those published by NHS England is because of different methods of counting and reporting, the ONS explained.
The figure of 1,649 deaths in hospitals in England up to March 27 (published by NHS England on April 5) is slightly higher than the equivalent figure for deaths both within and outside of hospitals in England up to March 27 (and registered by April 1) from the ONS, which is 1,568.
This is because numbers produced by the ONS take longer to prepare as they have to be certified by a doctor, registered and processed.
But once ready, they are the most accurate and complete information available, the ONS added.
The Department of Health provides an update on confirmed cases and deaths every afternoon.
In its most recent update, it said 51,608 people have tested positive as of 9am on Monday.
The number of hospital deaths was 5,373 as of 5pm on Sunday.
