That would be a good joke, if not for the fact that COVID-19 can lead to cardiac problems. If there are deaths being mis-labeled, we need to get to the bottom of it. However, if coronavirus put you in the hospital and you die, then coronavirus killed you. They count flu deaths the same way.
If you have a heart attack and you die, you died from heart attack, irrespective of if some signs of coronavirus were found or not.
If you are shot and died, you died from gun shot wounds irrespective of any coronavirus anti bodies.
Next you are going to tell us the coronavirus made the guy go and provoke someone to shoot him.
Your double speak will not be out of place in Orwell’s 1984.
