Explanation:

What term describes a constant number of infections in a region?

Now, there are a few terms we could use for this.

Sometimes, it may be referred to as a baseline (because that's the level its typically at--the "constant" number)

Baseline also can be called "endemic" (the constant presence)

The -endemic really just means persistent, so "hyperendemic" is a persistent high-level, which could be the baseline for that region

epidemic/cluster/outbreak/pandemic are all when we variate strongly from the baseline/expected number of infections

hope this helps! have a lovely day :)
