Question

1. In a country with a population of 16 million people, 175,000 deaths occurred during a year. These included 45,000 deaths from tuberculosis (TB) in 135,000 persons who were sick with TB. Assume that the population remained constant throughout the year. What was the case-fatality rate (CFR) from TBs?

Answer 1

33 %

Step-by-step explanation:

The case fatality rate is defined as the ratio between the total number of people in a population that died from a certain case by the total number of people affected by the case in a population.

Here, the number of people who died from TB is 45000 and the total number of people who were sick with TB was 135000.

`\text{Case fatality rate}=\frac{\text{Total number of people in a population that died from a certain case}}{\text{Total number of people affected by the case in a population}}\\\Rightarrow \text{CFR}=(45000)/(135000)\\\Rightarrow \text{CFR}=0.33`

So, the CFR from TB was 33 %
