“Host and Viral Determinants of Infant and Childhood Allergy and Asthma”

Duration:  08/01/16 – 07/31/26

Current Year Direct Cost: $1,082,276

RSV is the leading cause of bronchiolitis and causes >100,000 infant hospitalizations in the US each year.  Studies have also revealed that severe RSV infection in infancy is associated with the later development of childhood asthma.  This application will examine the effects of both host genetic and immune response determinants, as well as the influence of specific RSV strains on severity of RSV bronchiolitis and childhood asthma.  The long-term objective of this proposed project is to define the relationship between infant respiratory syncytial virus (RSV) infection and the host response that enables asthma inception.
