From: A regime-switching SIR epidemic model with a ratio-dependent incidence rate and degenerate diffusion
The disease I goes extinct with probability one. The left figures are the Markov chain and the right figures are the probability density functions of model (1.4) with the initial value (S0, I0) = (0.3, 0.2) for i ∈ \({\mathbb{S}}\) = {1, 2}. The intensities of the noises are chosen as \({\sigma }_{1}^{2}=0.4\), \({\sigma }_{2}^{2}=0.4\).
