This is more of a clinical question and I am not a clinician. I do know from reading definitions in the methods sections of studies that the symptoms your client had fit the diagnosis "chorioamnionitis," which translates "inflammation of the fetal membranes." The "itis" ending means "inflammation" not "infection," so I misspoke when I called it "infection," although in my defense, it does seem to be loosely regarded as "infection."

My guess is that with mom and babe doing fine after the birth, their care providers decided there wasn't anything to be concerned about. They may also have done some testing such as, maybe, a white blood cell count, that was reassuring, but as I said, I'm not a clinician so I don't know what would be the usual follow up. Anyone who knows more about this can feel free to chime in.
