Dividing the number of deaths by the number of cured patients results in a death rate percentage of 16% or even higher. In Canada, the adjusted rate has been computed to be about 25%. This guy is no mathematician. You divide the umber dead by the TOTAL NUMBER OF CASES, not by the number of survivors. Doing it the way he suggests would lead you to believe that if 100 people get a disease and 10 die, the 10 deaths divided by 90 survivors = 11.1%. Clearly inflated abore the real 10% rate.
The 16% people is taken from the number of people which are finished with the disease. Thus if 200 people are infected and 16 have died and 100 people are still suffering from the disease at present and 86 have recovered then the mortality rate is 16%. The question is how many of the people who have been infected will die from the disease. Thus we get
mortality rate - m
number dead from disease - d
number who have fished disease and survived - s
Thus:
m = d/(d+s)
I am making no statement if this is the best way to calculate probable mortality but I note that China has a vested interest in minimizing the danger of the disease.
