Multiscale Modelling of HIV/AIDS Transmission Dynamics
… Can we use a multiscale model of HIV/AIDS transmission dynamics to assess the comparative effectiveness of health interventions that are implemented at different scale domains? To achieve the set objectives of the study, we use multiscale modelling approach, a new and emerging computational …

Secondary Transmission Dynamics of the West Nile Virus in Mosquitoes
… had occurred in the country. The secondary transmission cycles of WNV are typically overlooked in regards to their role in maintenance and survival of the virus in nature. The first component of this thesis was to investigate transovarial or transovum transmission (TOT) of WNV in Ontario …

A Stochastic Model for The Transmission Dynamics of Toxoplasma Gondii
… carry a Toxoplasma infection. However, the transmission dynamics of T. gondii has not been well understood, although a lot of mathematical models have been built. In this thesis, we adopt a complex life cycle model developed by Turner et al. and extend their work to include diffusion of …

A tool of "barcoded viruses" to study influenza virus transmission dynamics
… as a tool for studying the replication and transmission dynamics of influenza virus in vitro and in vivo. Five barcoded APR8 viruses were firstly used to investigate infection kinetics (e.g. single- and multi-hit events, particle clumping and temporal aspects of co-infection) in vitro. This …

Modelling the transmission dynamics of RSV and the impact of routine vaccination
… Given the importance of households in the transmission of respiratory infections, an exploratory household model was developed to capture the transmission dynamics of RSV A and B in a population of households. <br></br><br></br> <b>Results:</b> From the analytical work of the simple ODE …

Genomic insights into the host range and interspecies transmission dynamics of Staphylococcus aureus
… between different species, with some of these transmissions resulting in successful adaptation and ongoing transmission in a new species. Given an ever-increasing risk of zoonotic disease emergence due to changes in the humananimal interface, it is increasingly important that we understand the …

Impact of lockdown on COVID-19 transmission dynamics in Botswana : a mathematical modeling study.
… mathematical model was formulated to assess transmission dynamics of COVID-19 and impact of control measures undertaken in Botswana to deal with the pandemic. This study aimed at informing future decisions about lockdown by retrospectively examining its impact of implementation using a …

Assessment of the impact of awareness programs on the transmission dynamics of COVID-19
… There is an urgent need to understand the transmission characteristics of the virus in response to social interventions. This is important to evaluate the overall impact of such programs in the management of the disease. We seek to develop a mathematical model that characterizes the …

HIGH DIMENSIONAL TIME SERIES ANALYSIS AND ITS APPLICATION IN MODELING TRANSMISSION DYNAMICS OF DENGUE
… time series analysis to discover the underlying dynamics of dengue, which has an estimated 390 million infections occur around the world. By incorporating the weather conditions in a time-series-susceptible infectious-recovered model with newly proposed all-step-ahead fitting approach, we have …

Transmission Dynamics Of Mycobacterium Avium Subspecies Paratuberculosis In Closed Dairy Herds In The Us
… this work we present work focused on within farm dynamics of Mycobacterium avium subsp paratuberculosis (MAP) infection on commercial US dairies. We focused on using deterministic mathematical models informed by molecular epidemiology and analysis of longitudinal data to evaluate current …

Population genetics and transmission dynamics of Plasmodium falciparum in the Kavango East and Zambezi regions of Namibia
… 3) a lack of validated tools to supplement transmission estimates. Malaria positive samples tested with rapid diagnostic tests (RDTs) and dried blood spots (DBS) were collected with corresponding epidemiological data from health districts in the Kavango East and Zambezi regions of Namibia. …

Determining the Prevalence and Distribution of Tick-Borne Pathogens in Southeastern Virginia and Exploring the Transmission Dynamics of Rickettsia Parkeri in Amblyomma Maculatum
… second aim of this research was to determine the transmission dynamics of Rickettsia parkeri within its vector, Amblyomma maculatum. Although some rickettsiae are transovarially transmitted in ticks, little is known about the frequency and efficiency of this transmission route, and nothing is …

Molecular epidemiology, susceptibility profiles, outcomes and transmission dynamics in patients with extensively drug-resistant tuberculosis (XDR-TB) in two provinces of South Africa
… health interventions required to interrupt transmission. In particular, the utility of certain costly drugs, e.g. capreomycin, for the treatment of XDR-TB remain unclear. There are also few data about how these characteristics differ in HIV-infected persons. Finally, little is known about …

The Dynamics of Multi-Drug Resistant Organisms: Modeling Nosocomial Infection Control Measures
… patient history classes, is created to model the transmission dynamics of Vancomycin-Resistant Enterococcus and Methicillin-Resistant Staphylococcus Aureus. Analysis of the model is supported with numerical simulations. It is shown that infection control procedures, including the identication of …

Perfect Reconstruction of Digital Transmission Through Channels With Bounded Additive Noise
… framework is extended to capture time-varying transmission dynamics. This case includes linear time-varying preprocessing of the data that does not increase the power of the transmitted signal. We present necessary and sufficient conditions for perfect reconstructability and formulate a …

Computational investigation of pathogen evolution
… also serve as markers that can elucidate transmission dynamics or reveal how long a pathogen has been present in a given environment. Moreover, systematically probing portions of the pathogen genome that are changing more or less rapidly than expected can provide important clues about the …

Molecular epidemiology of the multidrug-resistant Escherichia coli sequence type 131-H30 lineage among U.S. children
… knowledge gaps about the epidemiology and transmission dynamics of H30 among U.S. children through the integration of high-resolution molecular data from clinical extraintestinal E. coli isolates with patient epidemiologic data. I observed that although H30 is less common among …
