In the simulations below, the parameters that lead to a strong change in the evolution of the curves seem to be the "minimum distance to avoid being infected" and the "probability of transmission if an infected trespasses the minimum distance to avoid infection". Nevertheless, the results are very sensible to the parameters.
Keep in mind that these are just simulations to understand how an epidemic evolves through the human net and they do not intend to represent reality.
I strongly encourage the reader to watch Simulating an epidemic by Grant Sanderson.

PS: The usual SIR model is not adequate to model the following cases. The parameters also vary with time.
1) Minimum distance to avoid infection from an infected 0.8. Should stay 0.8 (units) away from each other to avoid being infected (less aggressive).
|
2)Same parameters as in 1) except: Minimum distance to avoid infection from an infected 1.2. Should stay 1.2 (units) away from each other to avoid being infected.
|
3) Same parameters as in 1) except: (Minimum distance to avoid infection from an infected 1.7. Should stay 1.7 (units) away from each other to avoid being infected)
|
4) Simulating an epidemic. Same parameters as in 1) except: Minimum distance to avoid infection from an infected 2.2. Should stay 2.2 (units) away from each other to avoid being infected (more aggressive)
