RSV is contagious and spreads just like a common cold virus - from one person to another, entering the body through the eyes, nose, or mouth. It spreads easily through the air on infected respiratory droplets. Most commonly, the virus is spread in the following ways:
According to the CDC, symptoms can appear 4 to 6 days after contact with RSV. Symptoms of RSV infection usually include:
These symptoms usually appear in stages and not all at once. In very young infants with RSV, the only symptoms may be irritability, decreased activity, and breathing difficulties.
Almost all children will have had an RSV infection by their second birthday.
Most RSV infections go away on their own in a week or two. There is no cure for RSV and medications, like steroids and antibiotics, do not help with RSV.

The following groups of people are at increased risk of severe and sometimes life-threatening RSV:

Most people who get an RSV infection will have mild illness and will recover in a week or two. Some people, however, are more likely to develop severe RSV infection and may need to be hospitalized.
RSV can cause more severe infections such as bronchiolitis, an inflammation of the small airways in the lung, and pneumonia, an infection of the lungs. RSV is the most common cause of both bronchiolitis and pneumonia in children younger than 1 year of age. Some children with RSV may be at an increased risk of developing a bacterial infection, such as an ear infection.
