Influenza outbreak in a school of 420 students and the effect of symptom-based isolation policies in baseline scenario with no vaccine. Median (interquartile range) of all simulations in the baseline scenario. The duration measures the interval between the first and last day with at least two infected cases, and peak date is the day from January 1st.
