Coughing after influenza fever is often considered to be related to the flu itself or a combination of respiratory tract infectious diseases.
1. The flu itself: The flu is an upper respiratory tract infection caused by the influenza virus. The inflammation caused by the influenza virus will stimulate the mucous membrane of the pharynx or trachea and trigger a cough as a stress response. That’s why most patients with influenza fever will experience respiratory symptoms such as sore throat and cough;
2. With the combined respiratory tract infectious diseases: influenza during the onset of the body’s immunity will be reduced, the body’s immunity during the decline in bacteria, mycoplasma and other pathogens are prone to break through the respiratory system’s defense barriers to invade the respiratory mucosa triggered by inflammatory foci. These inflammatory stimulation of the respiratory mucosa can also trigger coughing symptoms, during the onset of the patient may be accompanied by pharyngeal swelling and pain, coughing up sputum, shortness of breath and even dyspnea and other respiratory symptoms.
If you feel unwell, it is recommended that you go to the hospital in time to avoid delaying your condition.
