Infection with influenza virus means suffering from influenza. Influenza is clinically characterized by acute onset of cold and high fever, headache, fatigue, generalized muscle pain and respiratory symptoms. In general, influenza can be treated with symptomatic treatment and antiviral treatment. Symptomatic treatment can be ibuprofen, compound licorice combination and other drugs, and antiviral treatment can be amantadine, oseltamivir, etc. The specific medication needs to be based on the condition. 1. Symptomatic treatment: for those with high fever and severe myalgia, we can use antipyretic and analgesic drugs, such as ibuprofen, acetaminophen, etc.; for those with dry cough, we can use Glycyrrhiza glabra compound, etc. For those with high fever and severe symptoms of intoxication, we should give them fluids and physical hypothermia, observe their condition closely, deal with the complication in time, and if there are secondary bacterial infections, we can use appropriate antibacterial drugs for the pathogens at an early stage. 2. Antiviral therapy: This method is most effective when used within 48 hours after the appearance of influenza symptoms, which can relieve symptoms and reduce the duration of the disease. For influenza A virus, M2 ion channel protein inhibitors can be used, such as amantadine or amantadine, etc., which may cause dizziness, insomnia and other adverse reactions. Use with caution in hepatic and renal dysfunction, and contraindicated in pregnant women, infants, and patients with psychosis or epilepsy. Neuraminidase inhibitors, such as oseltamivir and zanamivir, may be used against influenza A and B viruses, and oseltamivir is occasionally associated with adverse reactions such as nausea and vomiting. Influenza patients are advised to seek prompt medical attention and follow medical advice.
