Respiratory syncytial virus (RSV) infection

Respiratory syncytial virus infection (RSV) is a common childhood infection. It can cause a runny nose, coughing, and wheezing. Most people get over RSV with home care.

In some people, especially young children, RSV may lead to pneumonia or another breathing problem called bronchiolitis. When this happens, oxygen and hospital care may be needed.

It may take older adults longer to recover from RSV and any problems caused by it than people in other age groups.
