Youre looking at a Monday, I'm looking at the 7 day average
https://www.worldometers.info/coronavirus/country/uk/
If you refer to the 'Deaths within 28 days of positive test by date of death' table over at
https://coronavirus.data.gov.uk/details/deaths?areaType=overview&areaName=United%20Kingdom - you can distill the latest seven day rolling average figures by hovering over the days in the table.
The latest 7 day average figure I could find is 164.4 - this was on the 6th February. When you consider that the table represents deaths over the last 28 days, this is essentially reading as an average of 164.4 against a timespan that saw daily case numbers range from 130,000 - 70,000.
So......
If we look at cumulative cases for the latest 28 day period (15th Jan - 13th Feb), we arrive at a total of 2,405,991 cases(nb. the last few days of this data is incomplete but that shouldn't materially change things)
7 day average of 164 deaths within 28 days of a positive covid test would give us an overall % of 0.007%.
At 0.007%, if this ratio continued we would be looking at around 3 deaths per 40,000 infections.
Usual caveats apply: Firstly, some of the data is comprised of an average which is never a great starting point. Secondly, whilst the deaths are averaged over 7 days, the numbers of cases it is measured against are exact and reported on a daily basis over 28 days.
Even so, it's quite clear that this is significantly less than 200 deaths per 40,000 infections.
