Basically, this model assume both of predator and prey are healthy. In this article, we develop alternative approach to describe predator-prey model with infected population. Infected population will conduct behaviour between predator and prey population. Stability analysis is done locally using Routh-Hurwitz criterion. In the end of this article, simulation is given to show comparation between numerical solution of nonlinear system with linearized.enPredator-prey modelRouth-Hurwitz criterionInfected Population
