How are COVID-19 deaths counted? It’s complicated

From the CDC:

Things to Know About Cause-of-Death Data Quality Getting high quality cause-of-death information can be challenging, especially during emergencies. Certifiers may be faced with heavy workloads, may not have access to complete information about the death, or may not be well trained in how to prepare good quality cause-of-death statements. The quality of cause-of-death data depends on death certificates being complete and accurate. • Complete means describing a clear chain of events from the immediate to the underlying cause of death, reporting any other conditions that contributed to death, and providing information that is specific. • Accurate means reporting the correct conditions as causes of death. Cause-of-death information is not perfect, but it is very useful. Current estimates are that about 20-30% of death certificates have issues with completeness
I have no reason to doubt you.....20-30% of death certificates having issues with being completed and having something wrong is possible but some folks will take that piece of data and run with it, exploit it as a reason that we have a very significant reduction in Covid 19 deaths and that's simply not the case
The misinformation could be cause of death or date of death/time/address, a whole host of issues
