Popis: Abstract In this paper, we consider a stochastic SIR epidemic model with regime switching. The Markov semigroup theory will be employed to obtain the existence of a unique stable stationary distribution. We prove that, if Rs0 $\mathcal{R}^{s}>0$ and β(i)>α(i)(ε(i)+γ(i)) $\beta(i)>\alpha(i)(\varepsilon(i)+\gamma(i))$, i∈S $i\in\mathbb{S}$, the densities of the distributions of the solution can converge in L1 $L^{1}$ to an invariant density.
