Ear infections occur due to viral or bacterial invasion of the ear canal, which primarily affects the middle ear. While infants and children are more prone to ear infections, adults can also suffer from the blockage of the Eustachian tube.

Causes of Ear Infections

Common causes of ear infections are:


1. Viral or bacterial infections

Viruses that cause inner ear infections include herpes viruses, polio, influenza, and Epstein-Bar virus. Bacteria associated with ear infections are Streptococcus pneumoniae, Streptococcus pyogenes, and Haemophilus influenza.


2. Eustachian Tube dysfunction

Most common in children, it occurs due to narrow passage of Eustachian tube in babies and toddlers or in adults having improper tube function. Children between the ages of six months to two years are at a higher risk.


3. Allergic Reaction

Children and adults having seasonal hay fever or allergies to environmental allergens can have ear infections.


4. Common Cold

In young children, even common cold can weaken the immune system and increase the chances of ear infections.


5. Family History

People having a family history of ear infections are at a higher risk of getting ear infections.


6. Swollen Structures

Enlarged or swollen parts of throat, ear and nose can lead to infections.

Smoking, excessive mucus in the trachea, changes in air pressure, long-term exposure to moisture and sinus infections.


When Should You Visit the Doctor?

The duration of an infection depends on the severity of the infection and how early you get treated. Middle and outer ear infections are quite mild and can heal over time. However, a chronic infection can take up to 6 weeks to recover.

Inner ear infections are most worrisome as they can lead to partial or complete hearing loss. The vestibular system associated with hearing and balance can get damaged due to prolonged infection.
