Colds are generally divided into common colds and influenza. For a common cold, one can visit the department of respiratory medicine; if this department is unavailable, one may alternatively visit the general internal medicine department. This disease can also be treated at community hospitals under the general practice department. Additionally, influenza is a contagious disease, so it is typically advised to seek treatment at a fever clinic or a clinic specializing in infectious diseases. If these options are not available, it is recommended to go to a hospital that can treat influenza.
