This program allows users to graphically enter population and disease characteristics (e.g., the virulence of the pathogen, the likelihood of transmission), to set up an initial population, and then observe the changes in population characteristics and the prevalence of the disease through time.

Using modified SIR-type models (Susceptible-Infected-Recovered), Epidemiology allows students

  • to ask a variety of "what if" questions
  • to design and perform their own investigations
  • to explore the implications of various public health policies

The direct-manipulation, graphical interface encourages exploration, and makes the program accessible to introductory students.
