# SIR Simulation of Disease Propagation

SIR is a MATLAB program which simulates the spread of a disease using the SIR (Susceptible/Infected/Recovered) model.

We consider the evolution of a disease epidemic in a population of N people.

We assume that the patients can be classified as Susceptible, Infected or Recovering, with the properties that:

• Susceptible: A patient who has never been infected with the disease. A susceptible patient can get the disease, controlled by a transmissibility coefficient beta.
• Infected: A patient who was susceptible, and has now contracted the disease. Infected patients spread the disease to susceptible patients. An infected patient can recover, with recovery coefficient gamma.
• Recovered: A patient who was infectious, but has recovered. Such patients cannot contract the disease, and cannot transmit it.

### Languages:

SIR is available in a MATLAB version.
