Influenza usually clears up in a few days, mainly related to the patient’s resistance. In most cases, the illness resolves itself in 1-2 weeks, usually in less than 10 days. For people with low immunity, the illness may be prolonged. Influenza, or influenza, is an acute respiratory infection caused by the influenza virus and is a self-limiting disease. The main clinical manifestations are high fever, headache, fatigue, generalized muscle aches and other toxic symptoms, but the respiratory symptoms are mild. If the body’s immunity is normal, the patient’s fever and malaise can generally be relieved in about 1-2 weeks, and most other symptoms such as cough and malaise can disappear in 10 days. In contrast, patients with impaired immune function, if left untreated, can easily develop into severe influenza, causing serious complications in various systems and even leading to death, with specific recovery times varying from person to person. During influenza treatment, patients should pay attention to drink more water and eat more vegetables and fruits. Overexertion should also be avoided.
