Effects of migration on vector-borne diseases with forward and backward stage progression
Derdei Bichara
Is it possible to break the host-vector chain of transmission when there is an influx of infectious hosts into a naïve population and competent vector? To address this question, a…
Global Analysis of Multi-Host and Multi-Vector Epidemic Models
Derdei Bichara
We formulate a multi-group and multi-vector epidemic model in which hosts' dynamics is captured by staged-progression framework and the dynamics of vectors is captured by an…
Role of short-term dispersal on the dynamics of Zika virus
Victor Moreno, Baltazar Espinoza, Derdei Bichara +2
In November 2015, El Salvador reported their first case of Zika virus (Zv) leading to an explosive outbreak that in just two months had over 6000 suspected cases. Many communities…
SIS and SIR epidemic models under virtual dispersal
Derdei Bichara, Yun Kang, Carlos Castillo-Chavez +2
In this paper, we develop a multi-group epidemic framework via virtual dispersal where the risk of infection is a function of the residence time and local environmental risk. This…
