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.
Ear Infections-Cause. Middle ear infections are caused by bacteria and viruses. Swelling from an upper respiratory infection or allergy can block the eustachian tubes, which connect the middle ears to the throat.iddle ear infections are caused by bacteria and viruses.
