The CFR will be an interesting (though tragic) data point, but I wouldn't generalize too much from it. The demographics of the inmates are probably not representative, and the health care that prisoners receive is absolutely not of the same quality that civilians may receive.

The Princess cruise was a good indicator of CFR for a specific demographic range when they tested early, often, and had access to quality care. If the CFR of this prison will tell us anything, it will be a counterpoint to such information showing what happens when quality of care is greatly diminished.
