Suggestions: 1. Check the blood routine again to understand the changes in the blood picture;

2. Do you have other symptoms besides fever? Check chest X-ray if necessary.

3. Try Chinese medicine decoction, it may be effective.

4. This time the blood picture was suspicious of viral infection, so the doctor gave antiviral treatment repeatedly. One possibility is that the antiviral time was short and the disease did not completely relapse; another possibility was that it was combined with bacterial infection. So the blood routine should be reviewed.
