Bronchiolitis (brong-kee-oh-LYE-tiss) is an infection of the respiratory
tract. It happens when tiny airways called bronchioles (BRONG-kee-olz) get infected
with a virus. They swell and fill
with mucus, which can make breathing hard.
Bronchiolitis is more common during the winter months. Most cases can be managed
What Are the Signs & Symptoms of Bronchiolitis?
The first symptoms of bronchiolitis are usually the same as those of a cold:
Most cases of bronchiolitis are mild and don't need specific medical treatment.
Antibiotics can't help because viruses cause bronchiolitis. Antibiotics work only
against bacterial infections.
Treatment focuses on easing symptoms. Kids with bronchiolitis need time to recover
and plenty of fluids. Make sure your child gets enough to drink by offering fluids
in small amounts often.
You can use a cool-mist vaporizer or humidifier in your child's room to help loosen
mucus in the airway and relieve cough and congestion. Clean it as recommended to prevent
buildup of mold or bacteria. Avoid hot-water and steam humidifiers, which can cause
To clear nasal congestion, try a nasal aspirator and saline (saltwater) nose drops.
This can be especially helpful before feeding and sleeping.
Talk to the doctor before giving your child any medicine. For babies who are old
enough, you may be able to give medicine to help with fever and make your child more
comfortable. Follow the package directions about how much to give and how often. But
cough and cold medicines should not be given to any babies or young kids. When in
doubt, call your doctor.
Babies who have trouble breathing, are dehydrated, or seem very tired should be
checked by a doctor. Those with serious symptoms may need care in a hospital to get
fluids and, sometimes, help with breathing.
Is Bronchiolitis Contagious?
Viruses that cause bronchiolitis spread easily through the air when someone coughs
or sneezes. Germs can stay on hands, toys, doorknobs, tissues, and other surfaces.
People can be contagious for several days or even weeks.
How Long Does Bronchiolitis Last?
Bronchiolitis usually lasts about 1–2 weeks. Sometimes it can take several
weeks for symptoms to go away.
When Should I Call the Doctor?
Bronchiolitis often is a mild illness. But sometimes it can cause severe symptoms.
When it does, kids need treatment in a hospital.

You know your child best. Call your doctor right away if something doesn't seem
Can Bronchiolitis Be Prevented?
Washing hands well and
often is the best way to prevent the spread of viruses that can cause bronchiolitis
and other infections.
Keep infants away from anyone who has a cold or cough.
