A Diffusive Sveir Epidemic Model with Time Delay and General Incidence.

Acta Math Sci 2021 1;41(4):1385-1404. Epub 2021 Jun 1.

Department of Mathematics, Swinburne University of Technology, Hawthorn, Victoria 3122 Australia.

In this paper, we consider a delayed diffusive SVEIR model with general incidence. We first establish the threshold dynamics of this model. Using a Nonstandard Finite Difference (NSFD) scheme, we then give the discretization of the continuous model. Read More

The severe acute respiratory syndrome COVID-19 was discovered on December 31, 2019 in China. Subsequently, many COVID-19 cases were reported in many other countries. However, some positive COVID-19 samples had been reported earlier than those officially accepted by health authorities in other countries, such as France and Italy. Read More

Epidemic Spread on One-Way Circular-Coupled Networks.

Acta Math Sci 2019 27;39(6):1713-1732. Epub 2019 Sep 27.

Department of Mathematics, Shanghai University, Shanghai, 200444 China.

Real epidemic spreading networks are often composed of several kinds of complex networks interconnected with each other, such as Lyme disease, and the interrelated networks may have different topologies and epidemic dynamics. Moreover, most human infectious diseases are derived from animals, and zoonotic infections always spread on directed interconnected networks. So, in this article, we consider the epidemic dynamics of zoonotic infections on a unidirectional circular-coupled network. Read More
