A Stochastic Differential Equation (SDE) of SARS disease will be discussed in this article involving the randomness of transmission and recovery rate parameters. Intervention of medical mask and medical treatment will be included in the model in order to get a better understanding about a possibility of scenario to control the spread of SARS. Based on the infectious data from Singapore and Hong Kong, the parameters of the model will be approximated by the Least Square method. Numerical simulations of infected individual will be derived by the Euler-Maruyama method. Numerical simulations investigates some possible intervention scenarios: using medical mask, medical treatment, and both interventions.
