RFK Jr responded to a question by stating he did not know how many died of COVID. At first glance that would be absurd. However after some thought it makes eminent sense. Why? Simple. Many of the nursing home patients for example had massive co-comorbidities. Namely they had cardiovascular issues, pulmonary issues, cancers, Diabetes, etc. So cause of death would be complex even with an autopsy.
If they tested positive for COVID, the actual cause of death may have been a heart attack, a stroke, etc. At best COVID was a co-morbidity. In the long run, no "cause of death" could be attributed. It is like so many aged, cause of death, pneumonia! It would be simple. Death certificates are notoriously in error unless the patient has been tracked with the full extent of the disease. Pancreatic cancer, lung cancer, massive stroke validate by imaging, may satisfy. But COVID and co-comorbidities, not so much.
The CDC should have understood that but they seem not to. Thus understanding COVID is still a mystery!
