Protect Against Respiratory Syncytial Virus

Grandson and grandfather

RSV usually causes mild, cold-like symptoms, but it can lead to serious illness, especially for infants and older adults. Wash your hands often to help protect yourself and others from RSV.

Respiratory syncytial virus, or RSV, can cause severe lung infections, including bronchiolitis (infection of small airways in the lungs) and pneumonia (an infection of the lungs). Each year in the United States, more than 57,000 children younger than 5 years old are hospitalized due to RSV infection. Additionally, about 177,000 older adults are hospitalized annually with an RSV infection, and about 14,000 of them die from it.

Those who have a higher risk for severe illness caused by RSV include:

  • Premature babies
  • Older adults, especially those 65 years and older
  • People with chronic lung disease or certain heart problems
  • People with weakened immune systems, such as from HIV infection, organ transplants, or specific medical treatments like chemotherapy

Know the Symptoms

Many of the first symptoms of RSV infection are similar to the common cold. Infants and young children may have:

  • Fever
  • Reduced appetite
  • Runny nose
  • Cough
  • Wheezing

Call a doctor if you or your child is having difficulty breathing, not drinking enough fluids, or experiencing worsening symptoms.

RSV is most common during fall, winter, and spring. It can spread through coughing and sneezing. You can also get RSV by touching surfaces that have RSV on them, then touching your eyes, nose, or mouth. Almost everyone gets RSV by the time they are 2 years old. Healthy people usually experience mild, cold-like symptoms and recover on their own within a week or two.

Help Prevent the Spread of RSV

You can help protect yourself and others from RSV infection by following a few prevention tips:

  • Wash your hands often. Wash your hands often with soap and water for 20 seconds, and help young children do the same. If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol. Washing your hands will help protect you from germs.
  • Keep your hands off your face. Avoid touching your eyes, nose, and mouth with unwashed hands. Germs spread this way.
  • Avoid close contact with sick people. Avoid close contact, such as kissing, and sharing cups or eating utensils with people who have cold-like symptoms.
  • Cover your coughs and sneezes. Cover your mouth and nose with a tissue or upper shirt sleeve when coughing or sneezing. Throw the tissue in the trash afterward and wash your hands.
  • Clean and disinfect surfaces. Clean and disinfect surfaces and objects that people frequently touch, such as toys and doorknobs. When people infected with RSV touch surfaces and objects, they can leave behind germs. Also, when they cough or sneeze, droplets containing germs can land on surfaces and objects.
  • Stay home when you are sick. If possible, stay home from work, school, and public areas when you are sick. This will help protect others from catching your illness.

If you have cold-like symptoms, you should take extra care to stay away from people who have a higher risk for severe illness caused by RSV. Whether this is possible or not, you should carefully follow the prevention tips above.

Children often pass the virus to one another at their school or childcare center. Limiting the time that high-risk children spend in these settings during the RSV season may help protect them from infection. For more information, see Reducing the Spread of Illness in Child Care.

There is no vaccine to prevent RSV infection yet, but scientists are working hard to develop one. There is a medicine that can help protect some babies. This medicine (called palivizumab) is a series of monthly shots. Doctors usually give the shots once a month during RSV season to infants and young children who have a higher risk for serious illness caused by RSV. If you are concerned about your child’s risk for RSV, talk to your pediatrician about these shots.
