What are the most common causes of ear infections?
assistant
The most common causes of ear infections include bacteria, viruses, and fungi. Bacteria can be spread by direct contact with another person’s infected mucus or saliva, as well as through water droplets that have been in contact with a person's mouth. Viruses are often transmitted through close contact with an infected individual such as kissing, sharing utensils, and using the same bathroom facilities. Fungi can be found in damp environments like bathrooms, swimming pools, and showers.
