The types and symptoms of a cold mainly include the common cold and epidemic cold, based on the causes of the cold. The common cold has relatively mild symptoms, mainly showing nasal congestion, runny nose, dry throat, dry tongue, and sometimes fever and headache may also occur. Epidemic influenza, mainly caused by influenza or parainfluenza virus infection, typically presents with symptoms such as chills, body-wide muscle soreness, and fatigue. Compared to the common cold, symptoms like nasal congestion and runny nose are relatively mild, but the principles of treatment are the same.
