Environmental variability in a stochastic epidemic model

作者:

Highlights:

• A stochastic epidemic model with mean-reverting process is developed.

• The stochastic extinction and persistence of the SDE model are given.

• The large intensity of volatility can suppress the outbreak of the disease.

• The smaller intensity of volatility can enhance the endemic dynamics.
