Bronchiolitis is an infection of the bronchioles, the small air passages in the lungs. It is common in infants and is the leading cause of serious lower respiratory illness.
Bronchiolitis is caused by a virus, especially respiratory syncytial virus (RSV), and frequently occurs in the late fall to early spring.
Symptoms of bronchiolitis include runny nose, cough, and fever. After a few days, your child may experience shortness of breath and/or breathing that is rapid and labored with wheezing. A severe infection in infants may cause a noticeably increased breathing rate.
If your child has heart disease or was born prematurely, call your doctor at the first sign of bronchiolitis.
Symptoms of bronchiolitis are the worst in the first 5 days. Most children get better in 1 to 2 weeks.
A doctor may diagnose bronchiolitis based on a medical history, your child's symptoms, and a physical exam. Testing is usually not needed if your doctor suspects the bronchiolitis is caused by RSV.
Home treatment to manage the symptoms of bronchiolitis is usually all that is needed. Have your child drink plenty of liquids to avoid dehydration. If your baby has a stuffy nose, use a suction bulb to remove mucus. Fever medicine (such as acetaminophen or ibuprofen) may help reduce fever discomfort. Over-the-counter cough and cold medicines are not recommended. Be safe with medicines. Read and follow all instructions on the label. Do not give aspirin to anyone younger than 20 because of the risk of Reye syndrome, a serious illness.
The doctor may suggest bronchodilator medicine if your child has shown the tendency to have allergic reactions (atopy). In severe cases, your child may need to stay in the hospital or get extra oxygen.
It is common for children to get respiratory problems (such as bronchiolitis caused by a viral infection), because they are often exposed to people who have infections to which they have not built up immunity. Bronchiolitis is spread just like a cold. To prevent bronchiolitis:
Sometimes medicines are used to help prevent respiratory syncytial virus (RSV) infections in babies and children who are at risk for problems from RSV.
