Modeling Temperature Effects on Vector-Borne Disease Dynamics
Vector-borne diseases (VBDs) cause significant harm to humans, plants, and animals worldwide. For instance, VBDs are very difficult to manage, as they are governed by complex interactions. VBD transmission depends on the pathogen itself, vector-host movement, and environmental conditions. …

Exploring the Multi-scale character of infectious disease dynamics
… characterised multiscale models of infectious disease dynamics. This was achieved by establishing when it is appropriate to implement particular mathematical methods for different multiscale models. The study of infectious disease systems has been elucidated ever since the discovery of …

Molecular ecology and hierarchical models elucidate chronic wasting disease dynamics
… scenario because a single gene codes for both a disease agent and a functionally constrained native protein. The prion precursor gene, Prnp, codes for the prion precursor protein, PrP, which is constitutively expressed as a native isoform within all mammals. Upon misfolding to the disease …

Behavioral Heterogeneity and Disease Dynamics in House Finches (Haemorhous mexicanus)
Infectious disease is a ubiquitous aspect of life on earth; however, parasites and pathogens are not distributed equally among individual hosts. Due to its ability to shape the way that individuals interact with other potential hosts and the environment, behavior is one of the most salient ways …

Shifting disease dynamics following the invasion of an emerging wildlife pathogen
… also the species that experience the most severe disease and greatest mortality, which reduces their contribution over time. Additionally, I found that pathogen growth rates and the harm the pathogen causes to hosts has declined since the introduction to North America. I also observed high …

A cholera model linking between-host, within-host and environmental disease dynamics
… infection with the Vibrio cholerae bacteria. The dynamics of the disease transmission are governed by human-human, environment-human, and within-human sub-dynamics. In this paper, a model is presented to incorporate all three of these dynamical components. The model is divided into three subgroups …

Host heterogeneity and respiratory disease dynamics: From structural inequity to immune history
Host heterogeneity is a core driver of infectious disease dynamics and has been widely explored in ecology and evolution. However, in human populations, social inequity remains underexplored as a source of heterogeneity despite having long been identified as a threat to global health and infectious …

Study of Behaviour Change and Impact on Infectious Disease Dynamics by Mathematical Models
… human behaviour changes' effects on infectious disease transmission dynamics. It centers on two main topics. The first concerns how behaviour response evolves during epidemics and the effects of adaptive precaution behaviour on epidemics. The second topic is how to build general framework models …

On the Effect of Ignoring Within-Unit Infectious Disease Dynamics When Modelling Spatial Transmission
… in the understanding of the spatio-temporal dynamics of infectious diseases in discrete time (Deardon et al., 2010). ILMs are generally fitted to epidemic data through Markov chain Monte Carlo (MCMC) methods in a Bayesian statistical framework. Here, we test the effect of ignoring within-unit …

Zoonotic disease dynamics in displacement: A multisite case study in Sindh, Pakistan and Mafraq, Jordan
… pathogens originates in animals. These zoonotic diseases are considered a threat to public health in emergencies and displacement, linked to changes in pathogen and vector environment. Although little is known about the exact disease dynamics due to scarce evidence, the fear of zoonoses has …

Modeling the Impact Of Environmental Factors, Diapause and Control Strategies on Tick and Tick-Borne Disease Dynamics
… vector responsible for a wide variety of diseases: ticks. Due to climate change, various tick species are rapidly spreading northward from the United States and have increasingly affected the Canadian population through a variety of tick-borne diseases including Lyme disease. In order to …

Multiscale Modelling of Environmentally Transmitted Infectious Diseases
… modelling approach in predicting the dynamics of infectious disease systems. Yet, there is still a lack of evidence that generally indicates which among the different categories of multiscale models of infectious disease systems is more appropriate to use in multiscale modelling of …

Analysis and Simulation for Homogeneous and Heterogeneous SIR Models
In mathematical epidemiology, disease transmission is commonly assumed to behave in accordance with the law of mass action; however, other disease incidence terms also exist in the literature. A homogeneous Susceptible-Infectious-Removed (SIR) model with a generalized incidence term is presented …

Changing Relationship Between Temperature and Pathogen Growth on Bats with White-nose Syndrome
Emerging infectious diseases (EID) pose significant threats to biodiversity. Human influence over the environment has increased opportunities for the introduction of novel pathogens to naïve hosts, potentially leading to host extinction. Understanding mechanisms of host persistence is critical for …

Mathematical modeling of infectious diseases
… we studied mathematical models of infectious diseases that consist of ordinary differential equations (ODEs) and partial differential equations (PDEs). An ODE model is formulated to describe the dynamics of wild mosquitoes when Wolbachia-infected female and male mosquitoes are introduced in …

Estimating network structure and propagation dynamics for an infectious disease : towards effective vaccine allocation
… contact network and of the propagation dynamics. In this thesis we develop a parameter estimation method that learns the network structure, among a family of graphs, and disease dynamics from the recorded infection curve, assuming that the disease dynamics follow an SIR process. We apply …

Bidirectional interactions between behavior and disease in banded mongooses (Mungos mungo) infected with Mycobacterium mungi
Behavior and disease interact bidirectionally and on multiple levels of host organization, and these interactions can have important consequences for population-level disease dynamics. I explored how behavior can both influence and respond to infectious disease in a banded mongoose population …
