摘要：
Based on uncertainty theory, this paper studies an uncertain SIS epidemic model with nonlinear incidence and demography. The solution, alpha-paths and uncertainty distribution of uncertain model are discussed. Under threshold conditions, extinction and permanence of the disease are studied by alpha-paths, which reveal the relationship of deterministic and uncertain models. An example is given to illustrate the above results.
