Question

A study starts with 4,875 healthy people. Over the next 2.5 years, 75 develop the disease. What is the incidence rate of disease over the study period?

Answer 1

The incidence rate of disease over the study period is 1.54%.

Step-by-step explanation:

The incidence rate of disease over the study period can be calculated by dividing the number of new cases of the disease by the total number of people at the start of the study, and then multiplying by a factor of 100 to express it as a percentage.

In this case, the number of new cases of the disease is 75, and the total number of people at the start of the study is 4,875. To calculate the incidence rate, we can use the following formula:

Incidence Rate = (Number of New Cases / Total Number of People) x 100

Plugging in the values, we get:

Incidence Rate = (75 / 4,875) x 100 = 1.54%

Therefore, the incidence rate of the disease over the study period is 1.54%.
