(Clockwise, a, b, c d) – Part of a multi-year simulation display for a city of 350,000 people. (2a., 2b.) Two alternative displays. Vertical scale demarcation is 10,000. Horizontal scale one year per demarcation. Simulation specifies asymptotic immunity decay period of 730 days. Intention is to simulate a virus with mutation leading to major epitope change over a period of 600 to 730 days. A continuous seeding of 3 attempts to infect a college student each day was defined. (2c. 2d.) A simulation of a single influenza epidemic in a 35,000 population. Vertical scale 1,000. Horizontal scale one month per demarcation.
