Compartmental Modeling
Discrete-time SIR modeling of infections/recovery
The model consists of individuals who are either Susceptible ([math]S[/math]), Infected ([math]I[/math]), or Recovered ([math]R[/math]).
The epidemic proceeds via a growth and decline process. This is the core model of infectious disease spread and has been in use in epidemiology for many years.
The dynamics are given by the following 3 equations.
where;
[math]S[/math] number of susceptible individuals,
[math]I[/math] number of infected individuals,
[math]R[/math] number of recovered individuals,
[math]\beta[/math] the average number of contacts per person per time,
[math]\gamma[/math] the transition rate.
