Figure 2a and 2b: Year 1 (Figure 2a) and Year 2 (Figure 2b) Comparative Population-based Incidence of Respiratory Viruses by Age Strata. The incidence of each virus per 100,000 persons (95% confidence intervals) overall and by the three age strata 18-49, 50-64, 65-79, and > 80 years of age are shown for year 1 and year 2. For both years and for every virus, the population-based incidence was highest for those > 80 years of age.
