A disease that occurs with predictability in one specific region or population is termed

• A. Endemic
• B. Epidemic
• C. Pandemic
• D. Sporadic

Answer: (A)

Endemic refers to a disease that is consistently present in a specific region or population, with a relatively predictable level of cases over time. The description in the question—occurring with predictability in one region—fits this idea of steady, baseline presence. In contrast, an epidemic is a sudden increase above expected levels, a pandemic spreads across many countries, and sporadic means cases occur irregularly without a predictable pattern. So the disease being continuously present in a particular area at a steady rate is the hallmark of an endemic.
