Otitis media is a common and frequent disease in the field of otorhinolaryngology, mainly caused by bacterial infections, such as Streptococcus pneumoniae and Staphylococcus aureus. Therefore, otitis media is generally not contagious. In certain situations where families live closely together, it is possible for two children to be sick at the same time; however, this is often related to the living environment or other upper respiratory infections, which does not indicate that otitis media is contagious. On the other hand, some specific infections may be contagious, such as tuberculous otitis media. The secretions from tuberculous otitis media are contagious, so it is important to differentiate between types of otitis media to determine whether they are contagious. Generally, otitis media is not contagious.
