Several commenters on yesterday’s post express a strong interest in learning the true level of mortality from the Chinese Virus. Are the numbers reported at sites like Worldometers as “Coronavirus Deaths” accurate and reliable, or are they inflated? Or, for that matter, could it be that the number of “Coronavirus Deaths” is under-reported for reasons that could include people dying at home without ever being tested?
My answer is that it is impossible to know at this point. The best indication we will get will come when the CDC issues final data for deaths from all causes in the U.S. for the month of April. When we get that number, we can subtract from it the approximate “normal” number of deaths that would have occurred anyway during April. The difference will be a good estimate of the number of excess deaths attributable to the virus. My prediction is that that number will be far less than the number of “Coronavirus Deaths” being officially reported. I’ll bet on about half or even less; but I’m the first to admit that I could be proved wrong.
The problem with attributing deaths to the virus begins with the fundamental problem of all scientific endeavor, which is that events in the real world have not just one but many causes. As a common example closely related to the subject of this post, many patients with cancer get pneumonia at the final stage of their disease. Did they die from the cancer or from the pneumonia? Or from both? When you look at the CDC statistics, you will see that each death has been assigned uniquely to just one of the major categories. In this case, each death has been assigned either to cancer or to pneumonia, not both. But how did someone decide that death A was from cancer, but death B was from pneumonia, when the patients had both and were in terminal condition? Generally, there is not much riding on the decision, and if it is made arbitrarily — half to one, half to the other — that’s probably fine.
