文摘
- •
We introduce Levy noise into a multi-strain SIS epidemic model.
- •
Stochastic stability of the disease free equilibrium is investigated.
- •
Sufficient conditions for persistence in the mean of the system are established.
- •
Numerical simulations for a stochastic two-strain model are presented.
- •
The findings indicate that Levy noise may suppress the disease outbreak.
