Did not have a high fever during illness? Did you have a high fever after recovery?

Patient's question:

I would like to ask a few questions about persistent low fever after full recovery from acute infectious diseases and the incomplete recovery of the body's temperature regulation system.
Does it refer to not having high fever during the initial illness period? Or does it mean having high fever after recovery? Or does it mean having high fever during the illness and still having high fever after recovery? Thank you.

Doctor's answer:

2-year-old female, persistent low fever after recovery from an acute infectious disease
Advice: Please tell me what infectious disease it is. Some infectious diseases may cause the condition you described, while others may not. It could also be related to medication, or the disease may persist internally even if it appears to have resolved. Additionally, it might be a symptom of another underlying condition.
The above advice is for the question "Persistent low fever and temperature adjustment system after acute infectious disease." I hope it helps. Wishing you good health!
