I recently participated in a science outreach event where I developed a web app to introduce infectious disease modelling to the general public. The main idea is that there has been a recent zombie outbreak and, given some data and models, the participant was required to investigate various hypotheses on its transmission, estimate the transmissibility and finally simulate what types of interventions would be required for its control.
Here is the link to the app or you can navigate to a section of the app from the images below.
