What we generally call a cold and cough belongs to the common cold, and those who are ill generally do not need to be isolated.
However, influenza is a contagious disease, so during the flu season, the elderly and infirm, pregnant women and children should take care to protect themselves by wearing masks and avoiding public places. Patients who are already infected with the influenza virus should isolate themselves at home, wear a mask and pay attention to cough etiquette.
