What is Swimmer's Ear? Outer Ear Canal Infection FAQ

How do people get Outer Ear Canal Infections?

Outer Ear Canal Infection (acute otitis externa) is commonly known as Swimmer’s Ear because it is frequently the result of trapped water breaking down the earwax and allowing bacteria to grow, but other damage to earwax can encourage bacterial growth.

How can I help avoid Outer Ear Canal Infections?

You should keep your ears dry after exposure to moisture from swimming or bathing. You should also avoid putting foreign objects in your ear2.

Do adults get Outer Ear Canal Infections?

Yes: 53% of Outer Ear Canal Infections occur in people 20 and older3.
