There is some interpretation to be done.
Many deaths are similar to that of Eddie Large.
He was admitted to hospital - virus free - with a serious heart problem.
He caught the virus in hospital and died.
Death may have been imminent anyway, so a reasonable view is the virus speeded his demise, but didn't entirely cause it.
It was the final straw that finished him off, but it's not quite accurate to day he died of the virus.
The BBC has taken to reporting such cases as '...died with corona virus' which is a fair attempt at getting the meaning across.
The NHS reports deaths as those with underlying health issues and those without.
Apportioning the impact of the two things is difficult.
No doubt some underlying health issue deaths will have been of patients who had lived with their underlying issue for a long time, and would have lived with it for years to come had they not caught the virus.
But some patients will already have been on borrowed time.
Ultimately, it may not matter.
The virus is fiercely contagious and can kill anyone, so the case to throw everything at it to stop it is already made.
