Any death that has had a confirmed positive test in the last 28 days is not necessarily a Covid death.
I'm not sure why you’re finding this so hard to grasp. It's not always the immediate thing that kills someone that's the important factor in the death. The
underlying cause of death is key.
To give an example from my work recently, a patient with leukaemia didn’t respond to treatment. Ultimately they got an infection (because they had no white blood cells) and died. What do you think should go on the death certificate? Is this an infection death or a leukaemia death? (it's leukaemia)
Or from the example of someone getting hit by a bus. No other factors, then fine, death by bus. Someone wandering along full of COVID keels over, unconscious, off the pavement and gets run over? That's a COVID death.
Ultimately, at the moment, the question is less important. Thousands more people are dying this year than in previous years. What are they dying from?
