From: A regime-switching SIR epidemic model with a ratio-dependent incidence rate and degenerate diffusion
The disease I goes to extinction exponentially with probability one. The left figures are the Markov chain while 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 \({\sigma }_{1}^{2}=0.8\), \({\sigma }_{2}^{2}=0.6\).
