Ear Infection Symptoms, Causes, and Treatment

What are the symptoms of acute middle ear infection in children and adults?

Signs and symptoms of middle ear infections in infants and children may include:

  • Young non-verbal children may be irritable and pull or tug at their ear(s).
  • Young children with middle ear infections may be irritable, fussy, or have problems feeding or sleeping.
  • Older children may complain about pain and fullness in the ear (earache).
  • Fever may be present in a child of any age.
  • The buildup of pus within the middle ear causes pain and dampens the vibrations of the eardrum (so there is usually temporary hearing loss during the infection).
  • Severe ear infections may cause the eardrum to rupture. The pus then drains from the middle ear into the ear canal.
  • The hole in the eardrum from the rupture usually heals without medical treatment.

These symptoms are often associated with signs of upper respiratory infection such as a runny or stuffy nose, or a cough.

In general, adults with an ear infection may have one or more of these symptoms and signs:

How common is acute middle ear infection or inflammation?

Otitis media is an extremely common diagnosis. In the U.S. it is estimated that 75% of all children experience at least one middle ear infection before the age of three.

Are ear infections contagious?

Ear infections are not contagious; however, many children develop ear infections following a cold or other viral infection, and those infections are contagious.

Why do infants and young children tend to have ear infections?

The Eustachian tube, a canal that runs from the middle ear to the back of the nose and throat, is shorter and more horizontal in infants and young children than in older children and adults. This allows easier entry into the middle ear for the microorganisms that cause infection and lead to otitis media. Young children also have more immature immune systems. The result is that infants and young children are at greater risk of acquiring ear infections than adults.
