Which statement best defines morbidity in public health terms for tuberculosis?

• A. The rate of tuberculosis infection in a population
• B. The death rate from tuberculosis
• C. The extent of TB transmission
• D. The severity of TB symptoms

Answer: (A)

Morbidity is about the burden of disease on a population—the number of people who are ill or affected by TB during a given period. It captures how widespread the illness is in the community, not how many people die from it (that’s mortality), not how the disease spreads (transmission), and not how severe the symptoms are for individuals (clinical severity). Therefore describing morbidity as the rate of TB infection in the population best reflects the overall impact of TB on public health. Keep in mind that infection (including latent infection) can be more widespread than active disease, but in public health terms morbidity focuses on the extent of illness burden in the population.
