Surely if someone died with the virus, rather than from the virus, then Covid19 is a contributory factor in their death, and should be on the death certificate along with whatever else killed them.
It reminds of my brother in law, who had cancer of the bowel. He died because he developed a pulmonary embolism, and that was the reason given on his death certificate. However, he wouldn’t have had the embolism if he hadn’t had cancer, because apparently cancer often causes people to develop blood clots. So to my mind, he died of cancer and the embolism, not just the embolism. But what do I know? I’m not a doctor.
