Bronchiolitis

Respiratory syncytial virus (RSV) is a very common virus that leads to mild, cold-like symptoms in adults and older healthy children. It can be more serious in young babies, especially to those in certain high-risk groups.

RSV is the most common germ that causes lung and airway infections in infants and young children. Most infants have had this infection by age 2. Outbreaks of RSV infections most often begin in the fall and run into the spring.

RSV is spread easily by physical contact. Touching, kissing, and shaking hands with an infected person can spread RSV. The disease spreads from person to person through contact with contaminated tiny droplets or objects that the droplets have touched.

RSV can live for a half an hour or more on hands. The virus can also live for up to 5 hours on countertops and for several hours on used tissues. RSV often spreads very rapidly in crowded households and day care centers.

The infection can occur in people of all ages.

Risks include:

• Attending day care
• Being exposed to tobacco smoke
• Having school-aged siblings
• Living in crowded conditions
