There are certainly cases where Covid-19 is a contributory factor to a death but is not the sole cause. This happens particularly where the patient has a serious underlying condition which could have caused death in due course but was hastened by Covid-19. It then becomes difficult to decide what was the true cause of death. This happens all the time, whether or not Covid-19 is involved. A patient with a severe heart condition develops pneumonia and dies. What killed them? The heart condition or the pneumonia? Surely the answer is that both problems, working together, caused the death. The same applies with Covid-19, and it would not be right to discount all such cases from the statistics and therefore seek to prove that the death rate from Covid-19 was going down.
