Figure 1.

Weekly age-stratified number of GP consultations for ARI in the Netherlands (dots) with model fit (lines) for age groups 0–1, 1–5, and 65+ years. Bold lines correspond to posterior medians, and shaded areas represent 95% credible ranges of the posterior distribution. Gray lines represent the total weekly numbers of ARI and colored lines represent ARI that was attributed to RSV. The sudden changes at the end of calendar years were caused by changes in the number of participating GPs, leading to changes in the size of catchment populations. Abbreviations: ARI, acute respiratory infection; GP, general practitioner; RSV, respiratory syncytial virus.
