If the effect of infusion is not very satisfactory after 3 days, it is necessary to change to a higher level of antibiotics, or check the blood to see if the white blood cells are high.

Therefore, it is recommended to observe the effect according to the clinical manifestation after 3 days of intravenous drug treatment. If the effect is not good, it is considered to be a viral infection, it is necessary to change the antiviral drugs for treatment.
