Hard to get a handle on the coronovirus issue. The Australian Dept. of Health are claiming a death rate of 3.4%, but seem to be miscalculating it.
They are calculating the number of deaths as a proportion of the number of infections, which is incorrect. When when you contract a deadly disease there are two possible outcomes: you either get better or you die. While you are still sick you are ‘unknown’.
Logically then, the correct calculation is the number of deaths as a proportion of infections which are resolved.
Using the correct calculation shows that it’s killing approx. 7.75% of people infected, though that does seem to be coming down slowly.
