Which term describes a disease that is consistently present in a population?

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

Answer: (B)

Endemic describes a disease that is regularly found within a particular population or area, with a relatively stable level of cases over time, sometimes showing seasonal fluctuations but without sudden large spikes. This ongoing presence contrasts with situations where cases surge beyond the expected level. An outbreak is a sudden, often localized increase in cases; an epidemic refers to a larger-scale increase that spreads beyond a small area; and a pandemic denotes a disease that has spread across many countries or continents. Endemic, in contrast, captures that persistent, baseline presence in the population.
