Evolution of the derivative of the number of infected people with time. | Exponential growth of infected people as a function of time. Rise time estimated in different time windows. |
Simulation of the outbreak: 500 individuals in a square 80x80. When they meet there is a 75% probability of infecting others if infected. Ecah infected individual has a probability of 4.5% to die, but it recovers after 150 steps, on average. Once recovered it cannot be infected. With 500 individuals the final population after 1000 iterations is of 360, all infected. |

Comparison between different regions. t=0 is when each region reached N>100 infected.

Comparison between different regions in log scale and relative to the maximum number of infected people reached in each of them. t=0 is when each region reached N>100 infected. The higher the slope, the faster the infection spread.
