How long it takes to recover from influenza A virus infection varies from case to case, and the time to recover is related to the patient’s own immunity and the amount of infected virus. The cold caused by influenza A is more serious than the common cold, if the patient’s body resistance is normal, the amount of influenza A virus infection is small, the symptoms such as fever, muscle aches and pains are not serious, and the mental condition is good, then drink more hot water and pay attention to rest to promote metabolism and ensure good immunity, usually about 1-2 weeks can be self-cured. If the patient’s body resistance is low and the amount of infection with influenza A virus is large, the patient often shows serious symptoms, such as high fever and generalized aches and pains, at this time, influenza A will not heal on its own and should be treated under the guidance of a respiratory doctor to avoid complications such as pneumonia. If you have a high fever, you should take cooling measures as soon as possible, such as placing a cooling ice pack on your forehead or wiping your whole body with warm water to physically cool your body, and give medication to cool your body if your temperature does not drop. In case of serious symptoms, it is recommended to go to the respiratory department of a regular hospital as soon as possible.
