Incidence refers to:

Incidence refers to:

• A. Occurrence of new cases of disease
• B. Prevalence of disease
• C. Mortality rate
• D. Recovery rate

Answer: (A)

Incidence is about new cases. It measures how many people develop a disease in a population over a defined period of time, reflecting the rate at which new occurrences occur. For example, if 50 people in a city of 100,000 develop a new illness in one year, the incidence is 50 new cases per 100,000 people per year. This is different from prevalence, which counts all people living with the disease at a given moment, regardless of when they were diagnosed. It’s also distinct from mortality rate, which tracks deaths, and from recovery rate, which tracks people who recover.
