People at risk for TB include individuals who were born in which area?

• A. High prevalence countries
• B. Low prevalence countries
• C. Delaware
• D. Coastal regions

Answer: (A)

TB risk is tied to how common the disease is in the birth region. People born in high TB prevalence countries are more likely to have been exposed to the bacterium and thus have latent TB infection or active TB, especially if they’ve recently immigrated or lived in crowded settings with limited healthcare access. In contrast, those born in low prevalence countries have lower exposure overall, so their risk is correspondingly lower. Being born in Delaware or in coastal regions isn’t a factor by itself; the key consideration is the TB prevalence in the country or region of birth.
