Patient's question:
Recently, I've been experiencing chest pain and tightness in my chest. The hospital examination indicated a respiratory disease, but the medication hasn't been very effective. Recently, my cough has worsened. Could you please tell me the cause of influenza?Doctor's answer:
Hello, influenza is an acute respiratory infection caused by the influenza virus. It is also a highly contagious and rapidly spreading disease. So, what are the causes of its onset? There are internal and external factors. The external factor is the presence of flu patients around you. So, the environment contains the influenza virus. This means that after inhaling the virus into the body, one becomes sick. After the virus enters the body, it causes illness. The internal factor is that the patient's resistance factors at the time are elevated. This leads to the development of influenza.
