Expert Solution
Step 1: Conceptual Introduction

The system of differential equations given describes a simplified model of disease spread.

The variable I represents the number of infected individuals, and S represents the number of susceptible individuals.

The term rI represents the rate at which infected individuals recover or die, and the term pSI represents the rate at which susceptible individuals get infected.
