Question

Assume a population of 3000 people of whom 20 are sick with lung cancer, and in 1 year, 9 of them die from the disease. Compute case-fatality rate from lung cancer.

A. 45%
B. 20%
C. 3%
D. 9%

Answer 1

The case-fatality rate from lung cancer is calculated by dividing the number of deaths by the number of people with the disease, resulting in a rate of 45%.

Step-by-step explanation:

To compute the case-fatality rate from lung cancer in the given population, we need to divide the number of deaths from the disease by the number of people with the disease, and then multiply by 100 to get a percentage. There are 20 people sick with lung cancer, and 9 of them die from the disease in one year. To find the case-fatality rate, we divide 9 (deaths) by 20 (sick with cancer), resulting in 0.45. When we convert this to a percentage, we get a case-fatality rate of 45%.

Calculation: Case-fatality rate = (Number of deaths from disease / Number of people with the disease) x 100 = (9 / 20) x 100 = 45%. Therefore, the correct answer is A. 45%.
