What is the matter with the child suddenly having a fever without any other symptoms?

Patient's question:

No

Doctor's answer:

If a child has a fever, it is best to seek medical attention at the hospital. The doctor will perform lung auscultation and throat examination, among other tests. It is recommended to check a blood test to determine if it is a viral or bacterial infection, and then treat accordingly.
For low-grade fever, drinking more water can help lower the temperature to normal. Generally, antipyretic medication is not recommended. If the temperature is high, exceeding 38.5°C, it is advisable to drink more water while taking antipyretic medication. If an infection is present, antibiotics and antiviral drugs should be taken simultaneously. If the condition cannot be controlled with medication in a timely manner, intravenous treatment is recommended.
