The aim of this paper is to give sufficient conditions, very close to the necessary one, to classify the stochastic permanence of SIQS epidemic model with isolation via a threshold value $ \widehat R $. Precisely, we show that if $ \widehat R<1 $ then the stochastic SIQS system goes to the disease free case in sense the density of infected $ I_z(t) $ and quarantined $ Q_z(t) $ classes extincts to $ 0 $ at exponential rate and the density of susceptible class $ S_z(t) $ converges almost surely at exponential rate to the solution of boundary equation. In the case $ \widehat R>1 $, the model is permanent. We show the existence of a unique invariant probability measure and prove the convergence in total variation norm of transition probability to this invariant measure. Some numerical examples are also provided to illustrate our findings.
