What are the symptoms of respiratory syncytial virus infection?

Coughing: In an infant the first signs is nasal congestion. Next there will be coughing and wheezing. The infant may have difficulty sleeping and nursing due to the congestion and cough. Fever is sometimes present. In severe cases there is rapid, labored breathing. An older child will have symptoms of a cold along with a bad cough and wheezing.

Multiple: Rsv has many symptoms and they can vary by age. It is most dangerous for infants, especially less than 6 months of age. Typically there is cough, nasal congestion, wheezing and coarse breath sounds, and fever. For an older child or adult, the symptoms generally mimic that of the common cold. In either case, time and supportive care are the best treatments.
