After cold viruses (such as rhinovirus, coronavirus, etc.) enter the human body through the respiratory tract, they first invade the mucosal cells in the throat. The virus replicates within cells, causing cell damage and death, thereby triggering a local inflammatory response. The following are the main mechanisms of sore throat after virus invasion:
| mechanism | Specific performance |
|---|---|
| Virus directly damages | The virus destroys cells in the throat mucosa, causing local tissue damage |
| inflammatory response | The immune system releases inflammatory factors (such as histamine, prostaglandins) that stimulate nerve endings |
| immune response | White blood cells gather and attack the virus, exacerbating local swelling and pain |
