What should I do if a child has a low fever of 37.1-37.4 at night for a long time?

Patient's question:

Main symptoms: Same as normal people
Onset time: 2-3 years
Laboratory test results: Normal

Doctor's answer:

Hello, in such cases, it is generally considered that tuberculosis is more likely. It is necessary to go to the hospital or epidemic prevention station to do a tuberculin test to check if there is a positive reaction. The results need to be observed after 72 hours, and after confirmation, treatment should be based on the symptoms.
