Spatial Infectious Disease Transmission Models: Variable Screening Methods and Logistic Formulation.
Infectious disease outbreaks have widespread consequences, affecting not only health, economies, and agriculture, but also global trade, social structures, and education (Rohr et al., 2019; Vurro et al., 2010; Anderson, 2002). Advanced mathematical models of infectious diseases, particularly …

Knowledge, Perceptions, and Practices: Mosquito-borne Disease Transmission in Southwest Virginia
… is to assess knowledge of mosquito-borne disease in southwest Virginia, as well as perceptions and practices of mosquito prevention. Given that several cases of La Crosse encephalitis have been reported in Wise and Tazewell counties, they were selected as study sites to conduct surveys. …

Mathematical modeling of zoonotic disease transmission under the impact of land use change
… impact of land use change. We develop a zoonotic disease transmission model that describes spillover of Puumala virus from bank voles to humans during land conversion. Our model introduces a land conversion index to capture the dependence of the carrying capacity and the death rate of bank voles …

Sexual networks of individuals infected with sexually transmitted infections: Structure and disease transmission
… - core groups. The objective was to examine STI transmission within these groups using both traditional epidemiology and social network analysis. Routine partner notification data, supplemented with more detailed voluntary information, was collected from individuals diagnosed with, or exposed to …

Understanding the Influence of Banded Mongoose (Mungos mungo) Social Structuring on Disease Transmission Using Molecular Tools
Understanding the disease transmission dynamics in wildlife species can be difficult and can prove more complicated if the population structure of a socially living species is shaped by territoriality. Understanding the connections and movements of individuals between groups is vital to documenting …

Utilizing a one health lens to determine various ecological and epidemiological drivers of vector-borne disease transmission
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2025-08-01

Assessment of the demographics and network structure of swine populations in relation to regional disease transmission and contro.
… when trying to define the potential for disease to spread within and between these populations. Disease spreads by non-mechanical means (as in aerosol transmission of PRRS virus) potentiates the need for knowledge of the neighborhood. Given the dynamic and transient nature of our swine …

Contributing factors to child stunting in Guatemala: A systems analysis focused on enteric disease transmission and mycotoxin exposure
"Child stunting -- low height-for-age -- is a United Nation's indicator for chronic malnutrition that has been linked to both acute and chronic health problems. Data from Guatemala suggests for children under five years of age, 49% are classified as stunted. This dissertation tests the following …

The Influence of Heterogeneous Landscapes on Banded Mongoose (Mungos mungo) Behavior in Northern Botswana: Inferences about Infectious Disease Transmission
Infectious disease transmission is driven by a complex suite of drivers with behavior and landscape dynamics contributing to epidemics across host-pathogen systems. However, our understanding of the interaction between landscape, behavior, and infectious disease remains limited. In the banded …

Assessment of Culverts and Bridges as Roosting Habitat for Perimyotis subflavus (tri-colored bat) and Disease Transmission Corridors for Pseudogymnoascus destructans
… United States, habitat characterization and disease monitoring has become vital to conserving remnant populations. Bats have been observed in multiple states using non-traditional habitat, such as interstate culverts, for roosting. To investigate their use of anthropogenic structures in …

Effects of Bird Feeder Density on the Behavior and Ecology of a Feeder-Dependent Songbird: Patterns and Implications for Disease Transmission
… at a site impacts wild birds in ways relevant to disease transmission. We manipulated the density of bird feeders (low versus high) available at otherwise similar sites and tracked the local abundance, body condition (scaled-mass index), feeding behavior, and movement across the landscape in wild …

Future Lyme Disease Risk in the Southeastern United States Based on Projected Land Cover
Lyme disease is the most significant vector-borne disease in the United States. Its southward advance over the last several decades has been quantified, and previous research has examined the potential role of climate change on the disease's expansion, but no research has considered the role of …

Individual-based modeling of white-tailed deer (Odocoileus virginianus) movements and epizootiology
… game mammals and potential reservoirs of diseases of domestic livestock, so diseases of deer are of great concern to wildlife managers. In many situations, models can be useful for integrating existing data, understanding disease transmission patterns, and predicting effects on host …

Theoretical epidemiology analysis of Plague, Polio, and Covid-19 outbreak
<p>Infectious diseases have been a persistent challenge to global health throughout history, and they continue to pose a significant threat in the present day. With the emergence of new diseases and the reemergence of existing ones, understanding the transmission dynamics, and developing effective …

Quantification of multiple waterborne pathogens in drinking water, drainage channels, and surface waters in Kampala, Uganda over seven months of seasonal variation
… seasonal variations in water quality, waterborne disease transmission, and future implications for climate change and public health. In this study, microfluidic quantitative PCR (MFQPCR) was used to assess the presence of human enteric pathogens in protected springs, a public tap, drainage …

Bloodmeal analysis of urban Western Australian mosquito species for improved public health outcomes
… studies assist in improving the understanding of disease transmission cycles, which can consequently inform disease mitigation measures. This study involved the capture and analysis of bloodfed mosquitoes within metropolitan Perth to determine their bloodmeal source. Mosquitoes were captured by a …

Identifying Novel Transcriptional Effectors of the Juvenile Hormone Pathway in Aedes aegypti
… zika, chikungunya, and yellow fever viruses. Disease transmission through this mosquito places over 40% of the world's population at risk of contracting one or more of these pathogens. Current control strategies such as insecticide application have failed or carry additional burdens, such as …

STUDIES IN THE DEVELOPMENT OF A XENOGRAFT-DERIVED BONE SCAFFOLD
… the risk of bone graft harvest and potential for disease transmission. Xenografts sources are an attractive alternative because of their relatively unlimited supply from a pool of healthy donors but have historically been limited by the alpha-Gal epitope which may lead to immune system rejection …

An impulsive differential equation model for Marek's disease
… employ impulsive differential equations to model disease transmission within an industrial livestock barn. In particular we focus on the poultry industry and a viral disease of poultry called Marek's disease. This system lends itself well to impulsive differential equations. Entire cohorts of …
