In a population of 1000, if 50 people are infected with a disease, what is the prevalence rate of the disease? (2023)

In a population of 1000, if 50 people are infected with a disease, what is the prevalence rate of the disease? (2023)

Step 1: Identify the total population. In this case, the total population is 1000.
Step 2: Identify the number of people infected with the disease. Here, 50 people are infected.
Step 3: Use the formula for prevalence rate, which is (Number of infected / Total population).
Step 4: Plug in the numbers: (50 / 1000).
Step 5: Calculate the result: 50 divided by 1000 equals 0.05.
Step 6: To express the prevalence rate as a percentage, multiply 0.05 by 100, which gives you 5%.

Prevalence Rate – The prevalence rate is a measure of the proportion of a population that is affected by a disease at a specific time.
