If you or your child has an ear infection, you might wonder: are ear infections contagious? The short answer is no—ear infections themselves cannot spread from person to person. However, the illnesses that cause ear infections, like colds and flu, are contagious.
What Causes Ear Infections?
Ear infections happen when bacteria or viruses get into the middle ear. This usually starts with another illness like a cold, flu, or allergies. According to the CDC, Streptococcus pneumoniae and Haemophilus influenzae are the two most common bacteria that cause middle ear infections.
When you have a cold or respiratory infection, the eustachian tubes (small tubes connecting your middle ear to your throat) can swell and become blocked. This traps fluid in the middle ear, creating a perfect place for germs to grow and cause an infection.
Why Ear Infections Seem to Spread
It may seem like ear infections spread between family members, but what actually spreads is the cold or flu virus. When one child catches a cold and their siblings catch the same cold, they may all develop ear infections. The infection is contained in the middle ear space and cannot jump from one person to another.
Why Children Get More Ear Infections
Children are more likely to get ear infections because their eustachian tubes are shorter, narrower, and more horizontal than adults'. This makes it harder for fluid to drain properly. The NIH reports that five out of six children will have at least one ear infection by their third birthday.
Prevention Tips
While you cannot prevent all ear infections, you can reduce your risk by:
- Washing hands regularly to prevent spreading cold and flu germs
- Staying up-to-date on vaccines, including flu and pneumococcal vaccines
- Avoiding secondhand smoke
- Breastfeeding infants for at least 6 months when possible
When to See a Doctor
See a healthcare provider if you or your child experiences ear pain lasting more than 2-3 days, fever of 102.2°F (39°C) or higher, pus or fluid draining from the ear, or hearing loss. Many ear infections clear up on their own, but some may need antibiotics.
