• Situation: Since we had a bad flu season, let's study the sensitivity of the severity of the outbreak on infection rate and time to recover. Assume there is a school with a 1000 students that are susceptible to the flu, 1 student that is infected, and 0 students that have recovered. The infection rate is 0.002 infections per interaction (between susceptible and infected students); i.e., students change from susceptible to infected at a daily rate = 0.002*number of susceptible students*number of infected students per day. If it is a 48-hour flu, then the recovery is 2 days.
•Questions of interest: When does the peak number infected occur? How many students are inflected at the peak? How long before everyone is recovered?
