Respiratory syncytial (sin-SISH-uhl) virus, or RSV, is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older adults. There is no vaccine for RSV but you can increase your child’s immune system by vaccinating against the flu. For more information on RSV visit: www.cdc.gov/RSV
