In clinical practice, ailments like the common cold, also known as upper respiratory infections, generally occur in patients due to reduced immune function, exposure to cold, or contraction of wind-cold, causing various symptoms such as nasal congestion, runny nose, sneezing, fever, dry and itchy throat, coughing, and pain. Therefore, as with the previous infection, most clinical cases are caused by viral infections. So, when patients suffer from upper respiratory infections, they often experience varying degrees of dry cough, which is very common. Typically, identifying the specific infecting pathogen causing the common cold and providing symptomatic treatment can lead to a full recovery within about a week. For severe dry cough symptoms, appropriate cough suppressant medications can be used for symptomatic treatment.
