Here is the translation of the given content into English: An 8-month-old baby has been running a low fever at night these past few days.

Patient's question:

No

Doctor's answer:

If you have a fever, it's best to find the cause. Low-grade fever is usually seen in viral infections, primarily in infants and young children, and is often associated with throat infections, without systemic symptoms. Routine examinations generally show no significant abnormalities, and there are no respiratory symptoms. Low-grade fever persists for a long time.
