Modelling leptospirosis outbreak using SIR hybrid optimization model.

Leptospirosis, as a potential worldwide public health problem, has been a notifiable disease in Malaysia since 2010. This paper aims to establish an epidemic model for the outbreak of leptospirosis, so as to better understand the dynamic trend of leptospirosis and provide theoretical basis for the government and health departments to formulate corresponding prevention and control policies. In this study, we proposed the SIR hybrid optimization model of leptospirosis based on Runge-Kutta fourth order (RK4) method, and obtained the simulation results of the outbreak process of leptospirosis from 2012-2013 to 2031-2032, and compared the results with actual data.
