What Is Swimmer’s Ear?
Swimmer’s ear (also known as otitis externa) is a bacterial infection typically caused by water that stayed in the outer ear canal for a long period of time, providing a moist environment for bacteria to grow. Anyone can get swimmer’s ear, but it is most often seen in children. Swimmer’s ear cannot be spread from one person to another.
Swimmer’s ear is not the same as a middle ear infection, which is also common in children.
