The disease transmission simulation allows you to examine the impact of four disease characteristics on the spread of disease through a population. The four disease characteristics and the range of values for each are listed in the table to the right.

Characteristic Range virulence (likelihood of dying) 0 (no victims die) to 0.75 (75% of victims die) duration of infection 1 day to 20 days rate of transmission 0.1 per day to 10 per day initial percent immune 0% to 100%

To use the simulation:

1. Set the desired values for the disease characteristics.
2. Click "Autorun" (automatically runs for 30 days) or "Run Day-by-Day"
   (allows you to step through 30 or fewer days).
3. Click "Reset" to start a new run using the same or different values for the disease characteristics.
