Cold is a disease of the upper whistle tract, which often results in coughing, and different measures should be taken depending on the condition. For patients with mild illness (i.e., no serious cold complications, no underlying diseases, and the general condition of the patient is also good), if the cough is mild, it can be treated conservatively, and the duration of the cold is often about 1 week, during which the cough can improve after the cold is cured as long as the patient drinks more water, eats regularly, ensures nutrition, and rests more. For those with severe cough, pseudoephedrine treatment can be given to reduce nasal congestion and cough symptoms, or symptomatic treatment with cough suppressant Chinese medicines. For patients with severe disease (e.g., elderly patients, pregnant women, patients with many underlying diseases, immunodeficiencies, or patients with severe complications such as hyperthermia, pneumonia, sepsis, etc.), they should be treated promptly at the hospital and given antiviral drugs (commonly used oseltamivir and ribavirin) as soon as possible under the guidance of a physician, in addition to symptomatic treatment to reduce the patient’s symptoms. When other complications occur, the complications should be treated promptly to protect the function of important organs, such as using antibiotics as soon as possible in case of secondary bacterial infections and correcting water-electrolyte disorders in a timely manner. Cold is a common disease, and symptomatic treatment is sufficient in mild cases, while preventive measures should be taken early in severe cases to prevent and treat complications in a timely manner in order to improve the prognosis.
