RSV can infect anyone, but is most dangerous in infants and the elderly. Its symptoms are similar to those of the common cold. They tend to run their course with only mild intensity in adults and older children. In infants and elderly, symptoms tend to be more severe, and can include fevers and wheezing. Some cases may require hospitalization, but most infections run their course within 1 to 2 weeks. A baby contracting RSV may require a lot of attention until recovery. However, be on the lookout for serious symptoms that can indicate a need for emergency treatment. If your baby is unusually tired, breathing rapidly or has bluish fingernails, call 911 or go to the ER immediately.
