Prevalence vs incidence

# For a given population, the number of disease cases are divided by the total number of people. Which of the following rates were calculated?
A. Odds ratio
B. Prevalence
C. Incidence
D. Specificity

The prevalence of a condition describes the proportion of a population who have acquired a condition.

Prevalence proportion is computed by comparing the total number of people affected with a condition against the overall number of people being studied. The result is usually written as a percentage, fraction, or by noting the number of known cases per 10,000 people or 100,000 people.

Incidence describes the number of new cases that occurred in a given population within a certain period.
