Comparison of the fit of the model to weekly influenza-positive SARI cases in all ages. Positive cases detected in the influenza surveillance system (black) with hypergeometric 95% confidence interval. Lines and shading represent the median (red) and 50% (green) and 75% credible intervals (blue) of the fitted model. Note that the model is fitted to age-specific data, but age groups are aggregated here for clarity. a Influenza B. b Influenza A(H3N2). c Influenza A(H1N1)pdm09). Influenza A(H1N1)pdm09) data from January 2010 to December 2012 were excluded from the analysis
