Question 1: Define "incidence" and "prevalence" and explain how they differ.
Answer:
● Incidence refers to the number of new cases of a disease occurring in a specific
population during a defined period. It measures the risk of developing the disease.
● Prevalence is the total number of cases of a disease (both new and existing) in a
population at a given point in time. It reflects the overall burden of the disease in the
population.
● Difference: Incidence measures new occurrences, while prevalence accounts for all
existing cases at a specific time.

strengths, and limitations.
