Threshold behavior in a stochastic SIQR epidemic model with standard incidence and regime switching

作者:

Highlights:

• A stochastic SIQR epidemic model with standard incidence and regime switching is studied.

• We obtain sufficient conditions for persistence in the mean of the disease.

• We establish sufficient conditions for extinction of the disease.

• We get sufficient conditions for the existence of positive recurrence of the solutions.

• The threshold between persistence in the mean and extinction of the system is obtained.
