Public Health England has changed its definition of Covid deaths. Hitherto, it counted anyone who died who had previously had a laboratory-confirmed positive Covid-19 test – irrespective of how long ago that test was The new definition introduces a time limit: the death of someone who tested positive no more than 28 days before death. The new data (here) means England has had 36,695 deaths using this definition as opposed to the previous reported 42,072 – a difference of 5,377. Here’s how the figures compare:
So the difference is more marked in June, July and August. For example, under the old system, 2,086 deaths were reported in England. With the 28-day cutoff, this number is 574 – nearly a quarter of what was previously reported.
The last two days illustrate the difference this change makes. As opposed to 100 deaths reported on the 11th of August, 11 would now be reported, and today, whereas 72 were reported there are only 15 under the new system.
Date | Ever had a positive test | Test with 28-day cut-off |
11/08/2020 | 100 | 11 |
12/08/2020 | 72 | 15 |
We have illustrated this effect on the seven-day moving average for July:
The change in definitions means the current moving average, as of the 12 August, is down to approximately ten deaths per day. But this still doesn’t change the league table for total deaths: the UK (and England) remain in the same position, above Italy. When it comes to deaths per million (i.e. adjusting for the population size) it means the UK’s death rate is similar to Italy and Spain and above France, whereas England alone death rate per million remains higher.
Country | Total deaths | Per million | Population |
UK | 41,329 | 609 | 67,926,890 |
England | 36,695 | 655 | 55,980,000 |
Italy | 35,225 | 465 | 65,290,273 |
Spain | 28,581 | 611 | 46,756,895 |
PHE uses two definitions of death in a person with Covid-19 in England, one broader measure and one measure reflecting current trends:
- A death in a person with a laboratory-confirmed positive Covid-19 and either: died within 60 days of the first specimen date or died more than 60 days after the first specimen date, only if Covid-19 is mentioned on the death certificate
- A death in a person with a laboratory-confirmed positive Covid-19 test and died within (equal to or less than) 28 days of the first positive specimen date.
