Swimmer’s Ear Treatment and Prevention

What Is Swimmer’s Ear?

Acute otitis externa — commonly known as swimmer’s ear — occurs when water is trapped in the outer section of the ear canal, resulting in inflammation and infection. When water remains in the ear, it creates a moist environment that aids bacterial growth. According to the Centers for Disease Control and Prevention (CDC) Associate Director for Healthy Water Michael Beach, swimmer’s ear is responsible for millions of dollars in medical costs each year.
