Prevention

No vaccine exists for respiratory syncytial virus. But these lifestyle habits can help prevent the spread of this infection:

• Wash your hands frequently. Teach your children the importance of hand-washing.
• Avoid exposure. Cover your mouth and nose when you cough or sneeze. Limit your baby's contact with people who have fevers or colds.
• Keep things clean. Make sure kitchen and bathroom countertops, doorknobs, and handles are clean. Discard used tissues right away.
• Don't share drinking glasses with others. Use your own glass or disposable cups when you or someone else is sick. Label each person's cup.
• Don't smoke. Babies who are exposed to tobacco smoke have a higher risk of getting RSV and potentially more-severe symptoms. If you do smoke, never do so inside the house or car.
• Wash toys regularly. Do this especially when your child or a playmate is sick.

Protective medication

The medication palivizumab (Synagis), given in the form of a shot (injection), can help protect certain infants and children 2 years old and younger who are at high risk of serious complications from RSV. High-risk children in this age group include those who:

• Were born prematurely
• Have chronic lung disease
• Have certain heart defects
• Have a weakened immune system

The first injection is given at the start of the RSV season, with monthly injections given during the season. This medication only helps prevent RSV infection. It does not help treat it once symptoms develop.

Talk with your child's doctor to find out if your child would benefit from this medication and to learn more about it. This medication is not recommended for healthy children or for adults.

Scientists continue working to develop a vaccine to protect against RSV.
