An increase, often sudden, in disease cases above baseline level is called

Explanation:
The main idea here is recognizing how we describe unusual increases in disease frequency. An epidemic is an increase in the number of disease cases above the expected baseline in a population, and it is often sudden and observed over a defined area and time. This makes it the best fit for the description, since it captures a broader rise in cases rather than just a few scattered ones. An outbreak is a more localized form of this phenomenon, typically confined to a smaller setting like a school or a neighborhood. A cluster refers to a group of cases in a specific area or time frame that appears to be more than expected, but isn’t necessarily wide-ranging. Sporadic describes cases that occur irregularly with no clear pattern.
