Figure 2From: The threshold of stochastic SIS epidemic model with saturated incidence rate Solution of system ( 1.3 ) with initial value \(\pmb{I(0)=1.5}\) and \(\pmb{\sigma=0.1}\) . In the left figure, the blue line represents the solution of system (1.3) and the black line represents \(I(t)\) in average of time. The right figure is a histogram of solution \(I(t)\).Back to article page
