Respiratory syncytial virus (RSV) is one of the most common causative agents of lower respiratory illnesses (including bronchiolitis and pneumonia) in infants and young children. RSV can be fatal and sudden deaths occurring in infants with respiratory disease are often believed to be due to this virus. In older children and adults, RSV causes an influenza-like syndrome, broncho-pneumonia, or exacerbations of chronic bronchitis. Approximately 70 percent of the population have antibody titers to RSV by the age of five years. However, these antibodies are not considered protective, as reinfection can occur.
