The humoral immune response norm eachy results in the development anti RSV neutralizing antibody titers, except they often are suboptimal during an infants initial infection. Even though it is robust, the humoral immunity wanes over time: reinf ection is common. Magnitude and intensit! y of infection and host response determine the severity of the disease. Epidemiology: it accounts for 50% of all pneumonia and 90% of broncheolitis in infancy. Outbreaks are abrupt in barrage and can lead up to 5 months. Epidemics occur annualy at predictable intervals. Peaks in the us are usualy during winter extending into spring, severity of outbreak usually varies. Fluctuations in circulating strands may leave to variation of severity.
