Which statement best defines morbidity in the context of tuberculosis as described?

• A. The rate of tuberculosis infection in a population
• B. The effect of tuberculosis on a defined group of individuals
• C. The death rate from tuberculosis
• D. The extent of communicability of tuberculosis within a community

Answer: (A)

Morbidity is about the illness burden a disease causes in a population. It focuses on the impact of tuberculosis on a defined group—the number of people who become sick, how severely they are affected, and how illness affects daily functioning and quality of life. That’s why describing the effect on a defined group best captures morbidity. The other ideas point to different concepts: infection rate measures how many people are infected, not necessarily ill; mortality is about deaths; and the extent of communicability relates to how easily the disease spreads.
