An ear infection can be caused by bacteria or a virus. It happens when fluid builds up in the area behind your baby's eardrum and then becomes infected. Normally any fluid that enters this area leaves pretty quickly through the eustachian tube, which connects the middle ear to the back of the nose and throat.
Identifying an Ear Infection. 1  1. Know who is most at risk for an ear infection. In general, children are more likely to get ear infections than adults. 2  2. Recognize the symptoms of a middle ear infection. A middle ear infection (acute otitis media) is the most common type of ear infection and is caused by a virus or bacteria.
