There are multiple causes for recurring ear infections, ranging from allergies, sinusitis, ear injuries, and bacterial infections from colds or flu. The Eustachian tube, which drains fluids away from the middle ear, may become plugged due to a viral or bacterial infection, allowing a buildup of fluid to press against the eardrum. Young children and infants are more likely to develop ear infections due to the Eustachian tubes' being smaller and more horizontal than those of adults, making it harder for fluid to drain away. Adults are more likely to get infections from swimming, injuries, or following upper respiratory illnesses. Wash hands frequently to reduce the spread of viruses and bacteria—often the root cause of the infection in the first place. Breastfeed infants to reduce upper respiratory illnesses, recommends the AAP. Keep vaccinations up to date for pneumonia, meningitis, and influenza. Since 2000, when the pneumococcal vaccine was introduced, the incidence of ear infections has dropped by over 20 percent.

The Eustachian tubes connect the middle ear to the back of the throat and help equalise pressure within the ear. If these tubes are not functioning properly, fluid can build up in the middle ear, providing a breeding ground for bacteria and leading to recurrent infections. Swollen adenoids can block the Eustachian tubes, leading to ear infections. Allergies and Sinusitis can cause swelling and blockage of the Eustachian tubes, increasing the risk of ear infections. Individuals with weaker immune systems, such as young children or those with certain medical conditions, are more susceptible to infections, including those of the ear. Infections in the tonsils can spread to other parts of your body, including your middle ear.

Ear infections can be more common in children because their immune systems aren’t fully developed yet, so they are more vulnerable to infections that wouldn’t affect an adult. The adenoid glands in the throat are often very active during infections, but they can sometimes trap bacteria that then passes through the eustachian tubes into the middle ear to cause an ear infection. The effects of ear infection in children can also be stronger because their eustachian tubes are smaller and less slanted than an adult's. It can be harder for fluid to drain out of the middle ear, especially when more is being produced because of an infection. The eustachian tubes are more likely to get blocked, meaning that ear infections can be more severe and persistent. The most likely cause of persistent ear infection in children is chronic otitis media. Persistent ear problems in children often happen because there is a build-up of fluid in the inner ear. The Eustachian tube isn’t draining this fluid properly. Fluid can also remain in the middle ear or keep coming back after the infection has gone, which means that the symptoms will persist.

Causes of otitis media, middle ear infections, include allergies, sinusitis, injuries to the ear and bacterial infections resulting from colds or flu. Inner ear infections are most often caused by a virus. Less rarely, they can be caused by bacteria. Outer ear infections are caused by bacteria, often from prolonged contact with water in which the bacteria is thriving. Chronic ear infections in adults can be a sign of a more serious health condition, including meningitis, stroke, heart disease and head injury. Outer ear infections are also sometimes caused by a fungus, such as yeast, as well as eczema. Rare outer ear infections can be caused by the flu or a certain type of shingles (Zoster oticus).

The eustachian tube runs from the middle of each ear to the back of the throat. This tube drains fluid made in the middle ear. If the eustachian tube becomes blocked, fluid can build up. When this happens, infection can occur. Ear infections are more common in children because their eustachian tubes are shorter, narrower, and more horizontal than in adults. A chronic ear infection may be caused by an acute ear infection that does not completely go away or repeated ear infections.
