Incidence of hospitalized RSV (per 1000 children) 2005–2013 with 95% confidence intervals.
Legend: Incidence per 1000 person years is given for each fiscal year from 2005 to 2013. Error bars shown are the calculated 95% confidence intervals. Closed circles (•) represent the incidence in the full Ontario cohort of children under 3 years of age. Closed triangles (▾) represent the incidence for children under 1 year of age. Open circles (ο) represent the incidence for children between 1 and 3 years of age.
