Global stability for an SEI model of infectious disease with immigration

作者:

Highlights:

• We study an SEI model of an infectious disease, including immigration of infecteds.

• There is no disease-free equilibrium.

• There is a unique endemic equilibrium and it is globally asymptotically stable.

• The disease cannot be eliminated unless immigration of infecteds is blocked.
