Answer 1

Answer:

C. An unusual increase in cases of an infectious disease that is already present in a specific region or population.

• Unusual Increase: This refers to a surge in the number of disease cases that is significantly higher than what is normally expected for that area and time period.

• Already Present: The disease isn't new to the region; it's an existing infectious disease whose incidence has suddenly escalated.

• Specific Region or Population: The increase is localized to a defined geographical area or a particular group of people.
