There are three types of ear infections, which are classified based on which part of the ear is affected:   ● Outer ear infection - Swimmer's ear, also referred to as otitis externa, is an infection that affects the ear canal. The ear canal is a tube that connects the outer ear to the eardrum. If water gets trapped in the ear after swimming or taking a bath, it can contribute to outer ear infections by creating a moist environment that fosters bacterial or fungal growth. ● Middle ear infection - Otitis media, also known as a middle ear infection, affects the middle ear. The middle ear is the space behind the eardrum and contains small bones that facilitate sound transmission. Most often, bacteria or viruses from the upper respiratory tract cause middle ear infections. ● Inner ear infection - Also known as labyrinthitis or vestibular neuritis, this type of infection affects the inner ear. The inner ear is responsible for balance and spatial orientation. Inner ear infections are usually caused by viruses, and they often cause symptoms such as dizziness, vertigo, and nausea.
