What is the reason for continuous fever?

Patient's question:

Coughing and fever for four nights and five days, now fever 38/39°C, not eating, went to the children's hospital for blood tests, results are good, also taking medicine

Doctor's answer:

Hello, based on the symptoms you described, it is considered to be acute bronchitis or pneumonia, among other conditions. For a definitive diagnosis, it is recommended to visit a hospital and consult a respiratory specialist for lung auscultation, blood tests, and other relevant auxiliary examinations. Generally, an elevated white blood cell count and a higher neutrophil percentage suggest a bacterial infection; if lymphocyte levels are elevated, it may indicate a viral or mycoplasma infection.
For bacterial pneumonia, the first-line treatment should be antibiotics such as penicillin or cephalosporins, along with symptomatic treatments like fever reduction, cough relief, and expectoration. For viral or mycoplasma pneumonia, antiviral medications and macrolide antibiotics should be the primary treatment, supplemented by symptomatic and supportive care.
It is important to rest, drink plenty of fluids, and consume foods rich in vitamins and protein to strengthen the body's immune response. The treatment duration is typically 7-10 days, or it may be extended appropriately based on the recovery progress. Wishing you a speedy recovery.
