In this work, we consider an epidemic model for corona-virus (COVID-19) with random perturbations as well time delay, composed of four different classes susceptible population, the exposed infectious population and quarantine population. We investigate proposed problem derivation at least one unique solution in positive feasible region non-local solution. For stationary ergodic distribution, necessary result existence is developed by applying Lyapunov function sense delay-stochastic approach condition extinction disease also established. Our obtained results show that effect Brownian motion noise terms on transmission very high. If large infection may decrease or vanish. validation our scheme, all have been numerically simulated.
