There is no easy way to work out exactly how many people are only there due to covid though, there has to be a standard or we will never have figures at all.
Take my mam for example. She had a collapsed lung (already had the other one collapse when she was 16), and at the same time developed bad COPD, so much so that she required oxygen for the rest of her life. Had she been around now and caught covid, I can pretty much guarantee she would have died.
After her first operation, the Doctor told me to prepare as the state of her lungs meant she would be lucky to have 6 months left. She survived over 3 years after that point.
So if she caught Covid a year after the Dr told us that, and it killed her (as it likely would have). Would it be put down as a Covid death or COPD? If she was fit and healthy Covid wouldn't have killed her so COPD?. If the Doctor was right, then she should have been dead by then anyway, so COPD? But she actually lasted over 3 years, and as she didn't catch Covid, then a Covid death had she have died?
Point is, when people have serious medical conditions, then it's not that easy to say what killed them. My view is, if Covid brought the death on sooner, or had any part in it, then it's a Covid death. If someone who died yesterday having tested positive for Covid, would have been alive today without a positive test, then the pre-existing condition didn't kill them.
