This project can be used to model virus infections throughout a country. The code is an exact copy of the matlab code from the website of Peter Forsyth. The parameters that are being modeled are
- S = susceptible population
- E = Exposed (infected, not yet infectious)
- I = Infectious (now can infect others)
- R = Removed (got sick, now recovered and immune, or died :( )
- N = total population = (S + E + I + R)
note: added cRI/N term: disease mutates and can cause reinfection or immunity lost. This assumes that mutated form jumps to Infected population. It can also be that a mutated form jumps to the Exposed population. For now, we assume c=0 (no mutation has been observed).
- dS/dt = -beta* S * I/N
- dE/dt = +beta* S* I/N - sigma* E
- dI/dt = +sigma* E -gamma* I + c* R* I/N
- dR/dt = gamma* I -c* R* I/N
