Respiratory syncytial virus, or RSV, is a respiratory virus that infects the lungs and breathing passages. Most otherwise healthy people recover from RSV infection in 1 to 2 weeks. Infection can be severe in some people, however, and infants born prematurely are particularly at risk – although babies born full term also contract the virus and can have complications or need to be hospitalized.
