What is the common infection known as 'swimmer's ear'?

The common infection referred to as 'swimmer's ear' is known as external otitis. This term specifically describes inflammation or infection of the ear canal, which can occur when moisture is trapped in the ear, creating an environment conducive to bacterial or fungal growth. Swimmer's ear is particularly common among individuals who swim frequently, as water exposure can lead to this condition.

External otitis typically presents with symptoms such as ear pain, itching, and sometimes discharge from the ear. It's distinct from otitis media, which refers to middle ear infections and is often associated with upper respiratory infections and colds. Aural atresia indicates a congenital condition where the ear canal is underdeveloped or absent, and myringitis involves inflammation of the eardrum itself, often due to infections or allergies. Hence, external otitis is the most accurate term associated with 'swimmer's ear.'
