What is the reason for a 4-year-old child's high fever that doesn't go away for several days?

Patient's question:

No

Doctor's answer:

Okay, here is the translation following your instructions:
It is okay to give the baby Hu Tong and Meilin Oral Liquid, the fever and cold medicine, for treatment. If a high fever occurs, you can use physical cooling methods. If the effect is not good, please go to the pediatric department quickly for a detailed examination and consultation.
