Bronchiolitis

Bronchiolitis is an inflammation of the bronchioles or small passages in the lungs. (Read about "Respiratory System") This inflammation can be caused by several kinds of viral infections, such as respiratory syncytial virus (RSV). (Read about "Respiratory Syncytial Virus") Children under age 2 are especially vulnerable, according to the American Academy of Family Physicians (AAFP), and most children are sick for about a week before getting well.

Symptoms can include a runny nose, slight fever, coughing, and wheezing. AAFP says mild cases can be helped by:

• using a humidifier to relieve your child's cough
• encouraging your child to drink plenty of fluids
• giving acetaminophen to reduce fever

AAFP says bronchiolitis is very contagious and it's important to wash your hands after taking care of your sick child to avoid spreading the virus to others.

You should also keep monitoring your child's symptoms and call a doctor if your child is vomiting and can't keep liquids down, is having difficulty breathing, or if your child has had heart disease (Read about "The Heart & Cardiovascular System") or was born prematurely.
