There is a very good article in The Spectator this week, by John Lee (a recently retired professor of pathology and a former NHS consultant pathologist) explaining the problems with what the mainstream media publishes about covid numbers and why it is easy to be confused.
He reckons the number of infections is vastly under-estimated, that the number of deaths is vastly over-estimated, and that the time scale of the disease matters.
This is his concluding paragraph:
The UK and other governments have no control over how their data is reported, but they can minimise the potential for misinterpretation by making absolutely clear what its figures are, and what they are not. After this episode is over, there is a clear need for an internationally coordinated update of how deaths are attributed and recorded, to enable us to better understand what is happening more clearly, when we need to.
