Respiratory syncytial virus (RSV) creates a significant healthcare burden for at least 5 years following acute infection, according to research published in The Journal of Infectious Diseases. The greatest burden occurs within the first two years after infection in infants.

Over a 5-year period, RSV cohorts had higher average all-cause cumulative hospitalization rates per 100 patient-years compared with controls, according to the study.

The rate for these RSV cohorts was 79.9 for early premature infants, 18.2 for premature infants, 34.2 for late premature infants and 16.1 for full-term infants with RSV. Infants with RSV also had higher rates of cumulative ER and physician visits.
