running a fever
Body fighting infection
Running a fever means having an elevated body temperature, typically from illness or infection.
The phrase treats fever as a continuous state the body maintains: She's been running a fever since yesterday.
Running here suggests something ongoing, like an engine running—the body keeps producing heat above normal.
