Abstract: The study is mainly concerned with mathematical modelling of peste des petit ruminant (PPR) disease using deterministic approach. A system of differential equations was formulated. Disease free and epidemic equilibria were calculated and used Jacobian Matrix to carried out stability analysis of the model. We then perform numerical simulations using Euler’s method. Sensitivity analysis with basic reproduction number were finally conducted to identify the most important parameters in the model. It was finally recommended that animal suffering from peste des petit ruminant (PPR) diseases should be immediately quarantined so as to reduce the contact rate between the infected and the susceptible and other items that have been in contact with the sick animals must be disinfected with common disinfectants.
