The most common causes of ear infections in children include viral infections, such as those caused by adenovirus and rhinovirus; bacterial infections, like strep throat or pneumococcal pneumonia; allergies, like hay fever; and immune system deficiencies. Other possible causes can include a blocked Eustachian tube (which connects the middle ear to the back of the nose), swimming in polluted water, and exposure to loud noises.
