Dynamic Transmission Modeling

Dynamic Model of Virus Transmission in Plants

In the study of viral diseases in plants, the immune response of the plant plays a basic role. In this paper, a mathematical model based on differential equations system with time delay for the immune response of the plant is introduced. As follows, the dynamical behavior of the model in equilibrium points is investigated. At the end, a plant in two different modes, organic and non- organic is ...

Modeling the Dynamic Transmission of Dengue Fever: Investigating Disease Persistence

BACKGROUND Dengue is a disease of great complexity, due to interactions between humans, mosquitoes and various virus serotypes as well as efficient vector survival strategies. Thus, understanding the factors influencing the persistence of the disease has been a challenge for scientists and policy makers. The aim of this study is to investigate the influence of various factors related to humans ...

Posterior Estimates of Dynamic Constants in HIV Transmission Modeling

In this paper, we construct a linear differential system in both continuous time and discrete time to model HIV transmission on the population level. The main question is the determination of parameters based on the posterior information obtained from statistical analysis of the HIV population. We call these parameters dynamic constants in the sense that these constants determine the behavior o...

Dynamic transmission modeling: a report of the ISPOR-SMDM Modeling Good Research Practices Task Force--5.

The transmissible nature of communicable diseases is what sets them apart from other diseases modeled by health economists. The probability of a susceptible individual becoming infected at any one point in time (the force of infection) is related to the number of infectious individuals in the population, will change over time, and will feed back into the future force of infection. These nonline...
