Question

Assume a population of 100,000 people of whom 20 are sick with disease X and in 1 year 18 of the 20 die from Disease X. What is the mortality rate and what is the case-fatality rate? Again, show the formula

Answer #1

mortality rate is calculated by dividing the number of deaths by the population at risk during a certain time frame.

Case fatality rate is calculated by dividing the number of deaths from a specified disease over a defined period of time by the number of individuals diagnosed with the disease during that time;

population consists of 100,000 people; 20 of these people have the specified disease, 18 of whom die from the disease. In this case, the mortality rate for the disease is 18 ÷ 1,00,000 = 0.00018, or 0.018 percent. The case fatality rate is 18 ÷ 20 = 0.90, or 90 percent

. A hypothetical example. In city A, with a population of
100,000 people, the weekly number of new cases of covid19 was 100
while in city B, with a population 1,000,000, the reported weekly
number of new cases was 1000. The news reported that city B
experiences a major epidemic while conditions in city A are under
control. What is the problem (if there is a problem) with this
statement.
a. There is no problem because city B indeed has...

Consider the following hypothetical diseases, and answer part A,
B, and C below: Disease X is very deadly with a mortality rate
>30%. However, it is only spread through bodily fluids and so is
difficult to transmit between people. Disease Y produces mild
symptoms, and has a mortality rate <1%. However, it can be
spread through the air and remains infectious on unwashed surfaces.
Because of this, it is extremely transmissible.
