Endemic is disease that occurs at an expected level in a population or in a certain location.

• A. True
• B. False
• C. It means the disease is eliminated
• D. It means the disease is newly emerged

Answer: (A)

Endemic describes a disease that is regularly present in a population or location at a baseline, expected level. It means the disease maintains a steady presence with incidence that stays within the historical or expected range given the setting, even though there may be some natural fluctuations. For example, malaria is endemic in parts of tropical regions, and chickenpox used to be endemic in many communities before widespread vaccination changed transmission patterns. This differs from elimination, which means transmission has been stopped in a defined area, and from a newly emerged disease, which has appeared in a population for the first time or after a long absence. So the statement is true.
