Introduction

Influenza refers to the flu. Generally, if the infection caused by the influenza virus is mild, the flu may resolve on its own. However, if the flu is severe and the patient's immune system is weak, it may not heal without treatment. If in doubt, it is recommended to consult a doctor. During flu season, try to minimize visits to crowded places to reduce the risk of infection.

　　Influenza refers to the flu. Generally speaking, if the influenza virus infection is mild, the flu may resolve on its own. However, if the flu is severe and the patient's immune system is weak, it may not be self-limiting. If in doubt, it is recommended to consult a physician. Detailed explanation is as follows:

　　If the influenza virus infection is mild and the patient only exhibits mild symptoms such as fever, cough, and fatigue, the immune system can gradually eliminate the virus through adequate rest, increased fluid intake, sufficient sleep, and consumption of nutrient-rich foods, leading to self-recovery.

　　If the influenza is severe, with widespread presence of the influenza virus in the patient's body and a weakened immune system, the likelihood of self-resolution is low. In such cases, patients may experience high fever, body aches, coughing, difficulty breathing, and even complications such as lung damage, heart damage, or nervous system impairment. Under these circumstances, prompt medical attention is necessary to prevent further deterioration of the condition.

　　During influenza season, try to minimize visits to crowded places to reduce the risk of infection. If travel to such areas is necessary, wear a mask to reduce the chance of viral transmission via droplets.

Can flu patients recover without taking medication?

If a patient with influenza has a good physical condition and strong immunity, their active immune response, combined with measures such as keeping warm, proper ventilation, hygiene, and a nutritious diet, may help eliminate the influenza virus from the body and achieve self-recovery. Many young, healthy individuals who regularly exercise and maintain a regular作息 (routine/lifestyle) may gradually recover within about a week.

Can mycoplasma pneumonia resolve on its own?

In general, a mild case of mycoplasma pneumonia may resolve spontaneously, but whether it can self-resolve depends on the individual patient's condition. During the self-recovery process, patients may experience symptoms such as coughing and low-grade fever. As the immune system gradually clears the pathogen, these symptoms will progressively subside and eventually disappear. If the patient's symptoms persist or worsen, or if complications arise, timely medical attention should be sought.

Does influenza A resolve on its own?

In general, for individuals with strong immune systems and mild symptoms, influenza A may resolve on its own. However, for those with weakened immune systems or severe symptoms, spontaneous recovery may not occur. For individuals with strong immunity, especially those without underlying medical conditions, infections with mild or common strains of the influenza A virus typically result in non-severe illness.
