Ear Infections in Children: Causes, Symptoms, Treatment & Prevention
Ear infection, particularly in the middle ear, often results from fluid buildup that becomes infected by bacteria or viruses. This condition, commonly referred to as acute otitis media, affects the space behind the eardrum, which is crucial for hearing.
What Is an Ear Infection (Acute Otitis Media)?
An ear infection, known medically as acute otitis media, refers to a rapid onset of infection in the middle ear—the air-filled area between the eardrum and inner ear. This part of the ear contains tiny bones that help carry sound vibrations from the outer ear to the inner ear.
The Eustachian tubes, narrow channels that connect the middle ear to the back of the throat, play a critical role in balancing ear pressure and clearing out fluid. When these tubes do not function properly, fluid can accumulate and lead to infection, especially when viruses or bacteria are present. This buildup often results in symptoms like muffled hearing and pain.

Ear infections are one of the most common childhood ailments, second only to the common cold. They are especially prevalent in children aged 6 months to 2 years, although children may continue to experience them until around age 8.
While adults and older children can also get ear infections, they occur less frequently in those age groups.
Why Are Children More Prone to Ear Infections?
Children are at greater risk of ear infections due to several factors:
- Underdeveloped Eustachian tubes, which are shorter and more horizontal than in adults, making fluid drainage more difficult.
- Immature immune systems, which are still learning to combat infections.
- Increased exposure to germs, especially in daycare or group settings.
Symptoms and Causes
What Are the Common Symptoms?
Ear infections typically develop after a cold or respiratory illness. Common symptoms include:
- Earache or a feeling of pressure in the ear
- Decreased appetite
- Difficulty sleeping
- Hearing issues in the affected ear
- Drainage of yellow, white, or brown fluid (may indicate a ruptured eardrum)
Important: If fluid is leaking from the ear, do not insert anything into the ear canal, as this can worsen the damage.
Symptoms in Infants and Toddlers
Since young children cannot always articulate their discomfort, signs to look for include:
- Tugging or rubbing at the ears
- Excessive crying or irritability
- Fever (typically between 100.5°F and 104°F / 38°C to 40°C)
- Refusal to eat or drink
- Breathing through the mouth or snoring, potentially due to swollen adenoids
What Causes Ear Infections Ear Infections in Children: Causes, Symptoms, Treatment & Prevention
Ear infections are typically caused by bacteria or viruses that migrate to the middle ear after a respiratory infection. These pathogens can lead to inflammation and blockage of the Eustachian tubes, resulting in fluid buildup and infection.

Are Ear Infections Contagious?
While the ear infection itself isn’t contagious, the viruses and bacteria that trigger them—like those that cause colds and the flu—are. These germs can spread easily in group environments like schools or daycares.
Risk Factors for Ear Infections Children: Causes, Symptoms, Treatment & Prevention
Several factors can increase the likelihood of developing ear infections:
- Young age (especially 6 months to 2 years)
- Family history of frequent ear infections
- Frequent colds, especially in group childcare settings
- Chronic health conditions, such as asthma or immune disorders
- Ethnicity: Higher incidence noted among Native American, Hispanic, and Alaska Native children
- Exposure to secondhand smoke or poor air quality
Possible Complications
While many ear infections resolve without issue, recurrent or untreated infections can lead to complications such as:
- Temporary or permanent hearing loss
- Delayed speech and language development
- Eardrum rupture, which may heal on its own but sometimes requires surgery
- Infection spread, including conditions like mastoiditis or even meningitis in severe cases
Diagnosis and Tests
How Are Ear Infections Diagnosed
A healthcare provider typically diagnoses ear infections by:
- Reviewing the patient’s symptoms
- Performing a physical exam, including the use of an otoscope to view the eardrum
- Checking for signs of inflammation, such as redness or swelling
- Using a pneumatic otoscope to detect fluid by puffing air into the ear and observing eardrum movement
Additional Diagnostic Tools
In some cases, further tests may be recommended:
- Tympanometry: Measures eardrum movement in response to pressure changes
- Acoustic reflectometry: Uses sound waves to detect fluid behind the eardrum
- Tympanocentesis: Removes and analyzes fluid for bacteria/viruses, used in stubborn infections
- Hearing tests: Especially for children with repeated infections to assess hearing loss
Treatment and Management
How Are Ear Infections Treated?
Treatment depends on several factors, including age, severity, and whether it’s a recurrent issue.
Watchful Waiting
In many cases, especially with mild infections, doctors recommend monitoring before prescribing antibiotics, as the infection may resolve naturally within a few days.
Antibiotics
Antibiotics are prescribed when:
- The infection is severe or prolonged
- The child is under 2 years old with infections in both ears
- Symptoms persist or worsen after 48 to 72 hours
It is essential to complete the full course of antibiotics, even if symptoms improve, to avoid recurrence.
Pain Management
Doctors may recommend:
- Over-the-counter pain relievers such as acetaminophen (Tylenol®) or ibuprofen (Advil®, Motrin®)
- Ear drops for localized pain relief
Avoid giving aspirin to children, as it can lead to Reye’s syndrome, a serious condition.
Ear Tubes (Tympanostomy Tubes)
For children with chronic or recurrent ear infections, ear tubes may be recommended. This involves:
- A brief surgical procedure to place a small tube in the eardrum
- Allowing air to flow and prevent fluid accumulation
- Tubes generally stay in place for 12 to 18 months and often fall out naturally
Outlook and Prognosis
Can an Ear Infection Heal Without Medication?
Yes, most ear infections—particularly mild cases—clear up on their own. Doctors may recommend delayed antibiotic treatment unless symptoms worsen.
When Can a Child Resume Normal Activities?
Once the fever subsides and the child feels better, they can return to school or daycare.
Prevention
Here are key strategies to lower the risk of ear infections:
- Prevent colds by encouraging frequent handwashing and minimizing exposure to sick individuals
- Avoid exposure to smoke, which can inflame the airways and Eustachian tubes
- Breastfeed infants during the first 6–12 months to strengthen immunity
- Feed babies in an upright position to prevent fluid from entering the middle ear
- Keep up with vaccinations, especially flu shots and those for pneumococcal disease
Living With an Ear Infection in Children: Causes, Symptoms, Treatment & Prevention
When Should You Contact a Doctor?
Seek immediate medical attention if:
- Your child has a stiff neck
- They appear very ill, listless, or cry uncontrollably
- Their walk is unstable or balance seems off
- There’s severe ear pain or a fever above 104°F (40°C)
- You notice facial drooping or weakness
Contact your provider during office hours if:
- Fever continues or returns after 48 hours on antibiotics
- Pain persists beyond three days of treatment
Common Questions
Should I Cover My Child’s Ears in Cold Weather?
No, ear coverage isn’t necessary unless it’s for general warmth or protection from extreme weather.
Can My Child Swim With an Ear Infection?
Swimming is generally safe unless there’s a ruptured eardrum or active drainage from the ear.
Is Flying Safe With an Ear Infection
Yes, flying is permitted, though it may cause temporary discomfort due to pressure changes. Encourage swallowing, chewing gum, or using a pacifier during takeoff and landing to relieve pressur.
