Bronchiolitis is an inflammation in the lungs. It affects the small breathing tubes. It is most common in children under 2 years of age. Children tend to get better after a few days. But in some cases, it can lead to severe illness. So a child with this lung infection must be treated and watched carefully.
Bronchiiolitis is an infection that involves the small breathing tubes of the lungs. The most common cause is the respiratory syncytial virus (RSV) but it can be caused by other viruses. The virus causes the bronchioles (very small breathing tubes in the lungs) to become inflamed, swollen, and filled with fluid. In small children this can lead to difficulties breathing and feeding. The symptoms start out like those of a common cold. They include stuffy and runny nose, sneezing, and a mild cough. Over a few days, your child may develop wheezing, trouble breathing, and a fever.
Antibiotics are not used to treat bronchiolitis unless a bacterial infection is present. Your child's health care provider may prescribe saline nose drops to help clear the mucus. In severe cases, your child may need to stay in the hospital. He or she may get intravenous (IV) fluids, oxygen, and breathing treatments.
The viruses that caused bronchiolitis spread easily. They can be spread through touching, coughing, or sneezing. To help stop the spread of infection:
Alcohol-based hand cleaners are recommended. Or, wash your hands with warm water and soap often. Do it before and after touching your child.
Keep your child away from other children while he or she is sick.
Call your healthcare provider right away if your child:
Has a deep, harsh-sounding cough
Breathes faster than normal, has trouble breathing, or has wheezing or a whistling sound with breathing
Is very sleepy or weak
Is an infant under 3 months with a rectal temperature of 100.4°F (38.0°C) or higher
Is a child of any age who has a repeated temperature of 104°F (40°C) or higher
Has a fever that lasts more than 24 hours in a child under 2 years old, or for 3 days in a child 2 years older
Has had a seizure caused by the fever
