An example of an epidemic model with a population slider and a graph. There are transmission rates and recovery rates built into the code and sliders to manipulate those variables. This model is specific to Ebola. Ebola has a transmission rate between 44-90%. The time as a carrier is between 2 to 21 days. The code accounts for both of these. Items that may be manipulated without changing the code are # of healthy, and sick at start, death rate which in real life is about 50%, days as a carrier, and transmission rate.
