Inferring Determinants of Viral Transmission using Short-Read Sequence Data
… genetic framework generating insights into viral transmission events based upon genome sequence data collected before and after transmission. Previous attempts at bottleneck estimation have neglected the underlying genetic structure of viruses, considering instead less informative single-locus …

Airborne Transmission of Influenza a Virus in Indoor Environments
… know remarkably little about the dynamics of the influenza virus in the environment during transmission between hosts. There is still controversy over the relative importance of various transmission routes, and the seasonality of influenza remains unexplained. This work focuses on developing new …

Modeling and responding to pandemic influenza : importance of population distributional attributes and non-pharmaceutical interventions
… prevalent approaches to the modeling pandemic influenza transmission, we present a simple distributional model that captures the most significant population attributes that alter the dynamics of the outbreak. We describe how diversities in activity, susceptibility and infectivity can drive or …

What influences Registered Nurses to have the influenza vaccine?
Influenza is a viral infection that can be spread from person to person by coming into contact with infected persons or objects that have been contaminated with the virus. The infection begins and the virus replicates in the ciliated columnar epithelial cells of the upper and lower respiratory …

Statistical inference in stochastic/deterministic epidemic models to jointly estimate transmission and severity
This thesis explores the joint estimation of transmission and severity of infectious diseases, focussing on the specific case of influenza. Transmission governs the speed and magnitude of viral spread in a population, while severity determines morbidity and mortality and the resulting effect on …

Applying Time-Valued Knowledge for Public Health Outbreak Response
… bots. Finally, we apply an agent-based model of influenza transmission to explore the efficacy of combined antiviral, sequestration, and vaccination interventions in mitigating an outbreak of an influenza-like-illness (ILI) within a simulated military base population. We find that while closed …

Mathematical modeling for epidemiological inference and public health support
… stochastic model of Varicella Zoster Virus (VZV) transmission, whose main novelty is the inclusion of realistic population dynamics over the last century. This chapter represents an attempt to answer the need pointed out by recent studies for a better understanding of the role of demographic …

The spatial and temporal anatomy of seasonal influenza in the United States, 1968-2008
… populations and is a driving force behind the transmission of influenza in temperate regions. Although the seasonality of influenza in temperate countries is widely recognized, inter-state spread of influenza in the United States has not been well characterized. This dissertation characterized …

From data to mathematical analysis and simulation in models in epidemiology and ecology
… we analyse collected data on the occurrence of influenza-like illness (ILI) symptoms regarding the 2009 influenza A/H1N1 virus pandemic in two primary schools of Trento, Italy. These data were used to calibrate a discrete-time SIR model, which was designed to estimate the probabilities of …

Mathematical model for tripledemic disease (COVID-19, RSV, and Influenza)
The concurrent circulation of COVID-19, Influenza (Flu), and Respiratory Syncytial Virus (RSV), collectively termed the ”Tripledemic,” poses substantial public health challenges due to their overlapping transmission patterns and compounded healthcare demands. The discovery of COVID-19 vaccines such …

A Fast-Graph Approach to Modeling Similarity of Whole Genomes
… dataset of over 4,200 globally sampled <italic>Influenza A virus</italic> isolates from multiple host types, subtypes and years. These sequences are compared using an alignment-free method that runs in linear-time. These comparisons enable us to build 2-dimensional graphs that represent the …
