So you are using the number of sick people as the denominator.
Do that.
Divide the number of recovered (8) by the number of sick (1100) and tell me the survival rate.
Divide the number dead (31) by the number of sick (1100) and tell me the fatality rate.
Do those rates add up to 100%?
Why not, hmmm?
1100 sick minus 8 recovered = 1092 dead?
You’re right, it’s panic time.
