On Modelling of Promiscuous Lifestyle; An SIR Dynamics

An epidemiological model depicting the dynamics of campus sex among students is analyzed in this study. For the purpose of this research, sexual activities among students is considered as a disease called SESEX. The Susceptible - Infected - Recovered (SIR) model is used in analyzing the dynamics in this scenario. Two equilibrium points were found, a disease-free equilibrium and an endemic equilibrium point. The model suggests that, admitting new students without the infection plays a significant role in the reduction of SESEX on campus. Thus, minimizing recruitment of infected students reduces the spread of the disease.
