Number of patients (cases) and incidence rates (number per million influenza patients) of the most severe abnormal behaviors of 10–19-year-olds in each season.

This figure shows the number of patients with the most severe abnormal behaviors of 10–19-year-olds, which are shown on bar charts, and incidence rates in number per million influenza patients, which are shown as bar charts in each season.
