It is very difficult to find the death rate using the previous criteria - I challenge you to find the numbers who died after 28 days with a positive test, and those where Covid was on the death certificate but the test was negative or not done. We are being manipulated - with the economy being the reason - politics is about manipulation, and sometimes it is for the overall good. Whether this manipulation of the numbers is a good thing is of course a matter of opinion.
Don't be mislead by this single case a "second" infection. The 33 year old male concerned had a pretty minor illness first time around, and was asymptomatic the second time. Whether the isolation the second time - with a different strain - was an infection or just "colonisation", like on a door knob, is not known, or, at least, not so far revealed. If they had good evidence of an active infection I would have expected them to give it.
