A cold should be seen in respiratory medicine because it is the most common respiratory infection, an acute upper respiratory tract infection with clinical symptoms of respiratory symptoms, including nasal congestion, runny nose, cough and sputum. Therefore, colds are usually seen in respiratory medicine in hospitals. If some smaller general hospitals do not have a respiratory medicine department, you can see a general internal medicine department, or you can see a general medicine department. Of course, if you are in a level 1 hospital, you only need to see a separate internal medicine department. However, if the clinical symptoms of a cold are mild and self-limiting, it is not necessary to go to the hospital at all, but just need to rest and drink warm water.
