Respiratory Syncytial Virus (RSV)

What is RSV?

Respiratory syncytial virus (RSV) is a common virus that infects the lungs and airways, including the nose, mouth, and throat. Most people who get RSV experience mild illness and recover at home within one to two weeks. However, infants, young children, older adults, and certain other groups are at higher risk for severe RSV disease.

Symptoms

RSV symptoms may include:

  • Runny nose
  • Coughing
  • Sneezing
  • Fever
  • Wheezing
  • Decreased appetite

Infants typically show symptoms, while adults can sometimes be infected without any signs. In children under 6 months, symptoms may include irritability, trouble breathing, loss of appetite and thirst, and reduced activity.

Vaccination

RSV vaccines are available for different age groups:

  • Older adults: Three single-dose vaccines are available for adults ages 75 and older, and for adults ages 50–74 who are at increased risk of severe RSV disease.
  • Pregnant people: Those who are 32–36 weeks pregnant between September and January can receive the RSV vaccine to help protect their babies from severe RSV.
  • Infants and older children: Young infants under 8 months old who are born during or entering their first RSV season, as well as some older children, may be eligible for RSV immunizations or monoclonal antibody treatments. Speak with your child’s pediatrician to determine the best protection for your child.

Prevention

In addition to vaccination for high-risk groups, help prevent the spread of RSV by:

  • Washing your hands often
  • Covering your coughs and sneezes
  • Sanitizing surfaces
  • Avoiding direct contact with others while sick
