Symptoms and Causes of Ear Infection

Human ear is divided into three sections - outer ear, middle ear and the inner ear. Ear infection is often the reason to visit an ear specialist. There are two main types of ear infection - otitis media and otitis externa. Otitis media is the infection of the middle ear, found mainly among infants and children. Otitis externa also known as swimmer’s ear is the infection of the external ear. Ear infection is more commonly seen in boys and in winter season. Ear infection is not contagious.

Causes for otitis media

The main cause of otitis media is blockage of the Eustachian tube due to cold, allergy or some foreign particles in the ear. This causes fluid to build up in the middle ear. This fluid can cause swelling of the ear drum if infected by the virus. If adenoid glands interfere with the Eustachian tube it will cause otitis media. Weak immune system will not cure the infection.

Causes for otitis externa

Otitis externa is caused by the bacteria or fungi. Moist and wet conditions are favorable for the growth of these bacteria or fungi. Frequent swimming or exposure to water increases the chances of infection. Skin allergies can also cause otitis externa.
