abstract = {<p style="text-align: justify;">We consider a stochastically forced epidemic model with medical-resource constraints. In the deterministic case, the model can exhibit two
type bistability phenomena, i.e., bistability between an endemic equilibrium
or an interior limit cycle and the disease-free equilibrium, which means that
whether the disease can persist in the population is sensitive to the initial
values of the model. In the stochastic case, the phenomena of noise-induced
state transitions between two stochastic attractors occur. Namely, under the
random disturbances, the stochastic trajectory near the endemic equilibrium
or the interior limit cycle will approach to the disease-free equilibrium. Besides,
based on the stochastic sensitivity function method, we analyze the dispersion
of random states in stochastic attractors and construct the confidence domains
(confidence ellipse or confidence band) to estimate the threshold value of the
intensity for noise caused transition from the endemic to disease eradication.</p>},
