Influenza A is self-healing. Mild and common types of the disease can be self-cured. However, in severe cases, it may be life-threatening if medication is not administered in time, so self-cure is not recommended. Influenza A is a contagious disease caused by influenza A. The infection and onset of the disease can lead to a variety of symptoms. After infection and onset of the disease, patients will have different degrees of colds, coughs, fever, sore throats and other uncomfortable symptoms. For people with a healthy immune system, a mild or common type of influenza A infection can be effectively treated by the immune system. However, for people who have been infected with influenza A and have developed severe illnesses or those with weakened immune systems, failure to use antiviral medication in a timely manner may result in a sustained increase in the viral load, leading to serious symptoms such as lung damage and shock, which may be life-threatening. Therefore, self-medication is not recommended and antiviral treatment should be given as soon as possible. After being infected with influenza A, you should go to the hospital to confirm the diagnosis and choose the appropriate medication or treatment plan under the guidance of your doctor.
