Cold is a disease of the upper respiratory tract, which is often associated with 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 better general condition of the patient), if the cough is only mild, it can be treated conservatively. 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 cough medicines can be given as symptomatic treatment. 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, or sepsis), they should be treated promptly at the hospital and given antiviral drugs (commonly oseltamivir and ribavirin) as soon as possible under the guidance of a physician, in addition to symptomatic treatment to reduce their symptoms. When other complications occur, the complications should be treated promptly and important organ functions should be protected. If a bacterial infection develops, antibiotics should be used as soon as possible and water-electrolyte disorders should be corrected promptly. Cold is a common disease, and symptomatic treatment is sufficient for mild cases, while early measures should be taken to prevent and treat complications in a timely manner to improve the prognosis when the disease is severe.
