COVID-19: The Disconnect between Cases and Deaths

As many (including me) have observed, COVID-19 case statistics don’t give a reliable picture of the spread of COVID-19 in the U.S. Just a few of the reasons are misdiagnosis; asymptomatic (and untested) cases; and wide variations in the timing, location, and completeness of testing.

So when you hear about a “surge” in cases, do not assume that they are actually new cases. It’s just that new cases are being discovered because more tests are being conducted. The death toll, overstated as it is, is a better indicator of the state of affairs. And the death toll continues to drop.
