Symptom Experience and Influenza-Like Illness in a Military Population
… presentation expressed over the course of an influenza-like illness (ILI) can predict virus type by use of unsupervised machine learning. The secondary objective was to describe clinical characteristics of strain specific coronavirus. Finally, examine the psychometric properties of the …

Detecting and mapping real-time Influenza-like illness using Twitter stream data
<p>Influenza has been identified by the World Health Organization as a global issue that could be more effectively served through an accelerated and widely-accessible public health surveillance tracking process. The ability to map and predict influenza outbreaks in a real-time heat map would be …

Positive Emotions and Immune Respose to Influenza in Medically Stable Older Adults
<p>Influenza results in substantial human suffering and health care costs. Evidence from psychoneuroimmunology suggests that emotions influence the immune system and may alter susceptibility to infectious diseases, like influenza. The purpose of this investigation was to evaluate the influence of …

Human mobility and spatial models for infectious disease
… spread of human infectious diseases such as influenza but obtaining human mobility datasets has historically been difficult. This thesis investigates two ways to represent human mobility in spatial metapopulation models for the spread of influenza in the US and UK – using gravity models with …

Going Viral: Internet and Social Media Based Surveillance Systems for Detecting Influenza Activity in Maryland
Influenza surveillance is essential for detecting and managing outbreaks. The Maryland Department of Health and Mental Hygiene (DHMH) currently includes the number of emergency room and physician visits for influenza-like-illness (ILI) to track flu activity. Recently, internet and social media …

Modeling and Predicting Incidence: Critical Systems Failures and Flu Infection Cases
… surveillance data, can we predict the impact of Influenza-Like Illness (ILI), including the percentage of outpatient doctors visits, the season duration, and peak? These two questions are related to modeling and predicting the incidence of different types of contagions. In the case of CI, the …

The performance of respiratory illness surveillance case definitions to detect Bordetella pertussis in children aged < 5 years seeking healthcare for respiratory illness in South Africa, 2017-2023
… We conducted a secondary analysis of respiratory illness surveillance data among children aged <5 years across sentinel sites from January 2017 through December 2023. Participants were enrolled as either outpatients eligible for influenza‐like illness (ILI), or hospitalised patients eligible for …

The Epidemiology and Control of Human Influenza in Vietnam
Understanding the epidemiology of human influenza in Viet Nam is important for developing local policies and also for understanding the dynamics of influenza in tropical and subtropical southeast Asia. I have analysed an 18 year time-series of influenza-like-illness (ILI) surveillance data, and …

On Shape-mediated analysis of spatiotemporal distributions
… was developed using weekly surveillance of Influenza Like Illness (ILI) cases at participating general practitioners (GPs) across France since 1988 as the study phenomenon. Covariate data came in the form of three hourly weather observations at locations across France. These two disparate …

Influenza : a study of contemporary medical politics
… prevention and control of seasonal and pandemic influenza has grown to be one of the largest and most visible public health policies. This dissertation considers contemporary influenza policy as a case study in what I call medical politics, in which a disease that for most people is rather …

Geographic and demographic transmission patterns of the 2009 A/H1N1 influenza pandemic in the United States
… describes how transmission of the 2009 A/H1N1 influenza pandemic in the United States varied geographically, with emphasis on population distribution and age structure. This is made possible by the availability of medical claims records maintained in the private sector that capture the weekly …

Data Integration Methodologies and Services for Evaluation and Forecasting of Epidemics
… and analysis of specific diseases, such as Influenza-like-illness. The modeling environments that support these systems are implemented for specific diseases and epidemiological models. Hence they are not reusable or extendable. This thesis focuses on the design and development of an …

Investigation of Swine Influenza Virus Genetic Diversity and Evolution
<p>Influenza A exists primarily in a waterfowl reservoir and readily infects numerous avian and mammalian species. In swine, numerous subtypes and antigenic lineages of swine influenza virus (SIV) co-circulate. The reassortment of viral RNA segments in cells infected by multiple viruses can lead to …

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 modelling of emerging and re-emerging infectious diseases in human and animal populations
… about the modelling of the 1999-2000 H7N1 avian influenza outbreak and of the 2009-2010 H1N1 pandemic influenza. From an applied perspective, parameter estimation is a key part of the modelling process and in this thesis statistical inference has been performed within both a classical framework …

Influenza Modeling, New York City, January 2000 to March 2010
<p>Traditional influenza surveillance methods require all reported cases to have a laboratory positive confirmed diagnosis, causing delays in outbreak detection. Many public health authorities have begun monitoring influenza-like illness (ILI) which does not require a patient to seek medical care …

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 …

Domain-based Frameworks and Embeddings for Dynamics over Networks
… How do we predict the peak intensity of the influenza incidence in an interpretable fashion? How do we infer the states of all nodes in a critical infrastructure network where failures have occurred? Leveraging domain-based information should make it is possible to answer these questions. …

Statistical estimation and changepoint detection methods in public health surveillance
… The first topic involves estimation of national influenza-associated mortality rates via mathematical modeling. The second topic involves the timely detection of infectious disease outbreaks using statistical process control monitoring. For over fifty years, the Centers for Disease Control and …
