A must-read. Here is a group of medical scientists explaining in lay person’s language why the tried-and-true methods established to determine “death rates” (more accurately case fatality rates) are necessary before making policy decisions based on reports based on faulty methods. The upshot: in this case, politicians will be well served using the best scientific knowledge at hand. The moral of the story: patience and planning are necessary.
