Instructions: 1. Set the sliders - Imm% of 80 and infection rate of 4 is a good starting point. 2, click green to populate the world. 3. Then release the virus by clicking the background somewhere.
An experiment in to infection rate and how immunisation rate can create herd immunity. Note the infection rate is a lot higher than it claims to be because each poorly person creates 'infection rate' clones of the virus, and each virus can infect any number of people.
