In a population of 10,000, if 200 people are infected with a disease, what is the prevalence rate of the disease? (2022)

In a population of 10,000, if 200 people are infected with a disease, what is the prevalence rate of the disease? (2022)

Step 1: Identify the total population. In this case, the total population is 10,000.
Step 2: Identify the number of infected people. Here, 200 people are infected with the disease.
Step 3: Use the formula for prevalence rate, which is (Number of infected / Total population).
Step 4: Plug in the numbers: (200 / 10000).
Step 5: Calculate the result: 200 divided by 10,000 equals 0.02.
Step 6: To express the prevalence rate as a percentage, multiply 0.02 by 100, which gives you 2%.

Prevalence Rate – The prevalence rate is a measure of the proportion of a population that is affected by a disease at a specific time, calculated as the number of infected individuals divided by the total population.
