Whether or not to use infusion therapy for acute upper respiratory infections mainly depends on the specific conditions of each patient with the infection. Generally, acute upper respiratory infections can usually be controlled within about a week with timely and effective treatment. However, a small number of patients may have persistent high fever or more severe clinical symptoms. In cases where oral medications are not effective, it is appropriate to use infusion therapy for symptomatic treatment. It is important to understand that the type of pathogens causing acute upper respiratory infections differs from patient to patient, as does each individual's immune function. Therefore, the clinical symptoms caused can also vary significantly. For cases of severe acute upper respiratory infections, or those with complications, it is sometimes necessary to use infusion therapy for treatment, as it can be more effective.
