The writer, or one of them, on how to understand and report figures for Covid deaths, is Dr John Lee. He is a recently retired professor of pathology and a former NHS consultant pathologist. There is an article by him in this week's Spectator though that's not where I first saw it.
I think the 'academic' side of this issue is important. It may seem removed from hard life, but it's pathologists and epidemiologists who, in practical terms, ultimately help us deal with things like Covid19 precisely by working out differences, and why they matter, such as the 'academic' one I mentioned above.
