There is no “fastest way” to treat influenza. The treatment of influenza includes general symptomatic treatment and early antiviral treatment. 1. General symptomatic treatment: Influenza is mainly characterized by sudden high fever, headache, fatigue, muscle pain, etc. Respiratory symptoms are mild. Respiratory isolation should be carried out as far as possible, pay attention to rest, oxygen therapy, high fever can be given antipyretic sedatives such as ibuprofen tablets, children should avoid the use of aspirin. If the vomiting is severe, appropriate rehydration can be given. 2. Early antiviral therapy: it can inhibit viral replication, reduce symptoms, shorten the course of the disease, and prevent complications. 48 hours of medication is effective. Commonly used drugs include amantadine, oseltamivir, zanamivir. Amantadine is only effective for influenza A. Oseltamivir and zanamivir can interfere with the release of the virus, and the course of treatment is usually 5 days. Vaccination is the basic measure to prevent influenza. Influenza treatment and medication should be standardized in accordance with medical advice.
