The COVID-19 pandemic is the most recent example that infectious diseases can disrupt and permanently alter how societies work and interact. This manuscript builds around a series of papers studying disease spread from the point of view of dynamical systems, using the COVID-19 pandemic as a working example. We first study the effect of including test-trace-and-isolate policies in compartmental models and describe their dynamical regimes. We find two tipping points between controlled and uncontrolled spread, defining a novel stable regime at low case numbers where long-term pandemic control ...

The COVID-19 pandemic has presented an unprecedented challenge to global health, prompting a need for comprehensive research into the coupled dynamics of virus spread, intervention strategies, and human behavior. This dissertation provides a significant contribution to our understanding of these interconnected dynamics. We begin by establishing a theoretical framework for analyzing stability in dynamical systems. With a bedrock of theoretical understanding, the dissertation advances into the practical realm, scrutinizing the impact of the COVID-19 pandemic in Europe. An expert consultation ...

The riveting account of how asymptomatic transmission drove COVID-19's global spread and catalyzed interventions to control it. Why was COVID-19 so difficult to contain and so devastating to people and economies worldwide? In Asymptomatic, author Joshua S. Weitz explains how silent transmission enabled COVID-19's massive and tragic global impact. Weaving the science of viral infections together with an insider's look at response efforts, Weitz guides readers through the shockwaves of successive epidemic waves as public health officials and academic research teams confronted the rise and risk of what was then a burgeoning global pandemic. The discovery of asymptomatic spread also fueled competing narratives: either COVID-19 was about to dissipate as quickly as it had emerged or completely disrupt life as we knew it. Weitz, a physicist-turned-biologist who directs a quantitative viral dynamics research group and has been immersed in COVID-19 response efforts, explains both why and how scientists tried to wade through competing narratives and warn the public of COVID-19's profound risk. As explored through a careful analysis of local outbreaks, accessible descriptions of virus dynamics, and the use of predictive models to guide response efforts, Asymptomatic provides readers a unique look into the secret ingredient that allowed COVID-19 to spread across borders and the high-impact interventions needed to fight it and future pandemics.

Mathematical Modeling, Simulations, and Artificial Intelligence for Emergent Pandemic Diseases: Lessons Learned from COVID-19 includes new research, models and simulations developed during the COVID-19 pandemic into how mathematical methods and practice can impact future response. Chapters go beyond forecasting COVID-19, bringing different scale angles and mathematical techniques (e.g., ordinary differential and difference equations, agent-based models, artificial intelligence, and complex networks) which could have potential use in modeling other emergent pandemic diseases. A major part of the book focuses on preparing the scientific community for the next pandemic, particularly the application of mathematical modeling in ecology, economics and epidemiology. Readers will benefit from learning how to apply advanced mathematical modeling to a variety of topics of practical interest, including optimal allocations of masks and vaccines but also more theoretical problems such as the evolution of viral variants. Provides a comprehensive overview of the state-of-the-art in mathematical modeling and computational simulations for emerging pandemics Presents modeling techniques that go beyond COVID-19, and that can be applied to tailoring interventions to attenuate high death tolls Includes illustrations, tables and dialog boxes to explain highly specialized concepts and insights with complex algorithms, along with links to programming code

Streptococcus pneumoniae, the pneumococcus, is a leading cause of pneumonia, meningitis and sepsis globally, and is hence a pathogen of major public health interest. The spread of antibiotic resistance and the emergence vaccine-escape variants pose particular challenges to public health interventions. The maintenance of antibiotic resistance at stable, intermediate frequencies, and patterns of post-vaccine strain replacement are indicative of complex interactions and competition. Mathematical models can provide key insights into the mechanisms which maintain diversity in multistrain pathogens such as the pneumococcus. Coinfection has been identified as an important mechansism behind the coexistence of drug-sensitive and drug-resistant phenotypes. Our analysis of compartmental models with coinfection highlight how subtle changes in the dynamics of secondary infections can have significant impacts on model dynamics and, in particular, in the ability of these models to generate multistrain coexistence. Often, the assumptions these models make regarding coinfection dynamics are difficult to justify and parameterize. We argue that in order to study key ecological patterns in the pneumococcus, a different modelling approach is necessary. To that end, we develop an agent-based nested model with explicit dynamics on both within-host and between-host scales. This modelling approach allows us to explore how within-host competition shapes long-term population-level patterns, as well as vaccine-induced dynamics. We furthermore show how modelling can be used to assess pandemic intervention strategies. Throughout the COVID-19 pandemic, modelling played an important role. In late 2020, as the first vaccines against COVID-19 began to be disseminated, the province of British Columbia initially proposed an age-based rollout strategy. We sought to evaluate the relative effectiveness of different vaccine rollout strategies by comparing age-based strategies to those which exploit contact structure by targeting so-called essential workers. Using an age-and work-structured dynamic transmission model for COVID-19, we show that in many jurisdictions there are benefits to targeting essential workers earlier than they would be using an age-based only strategy.

COVID Societies presents a compelling and accessible overview of key sociocultural theories that can help us make sense of the diverse, dynamic and complex elements of the COVID crisis. These include discussions of the political economy perspective; biopolitics; risk society and cultures; gender and queer theory; and more-than-human theory. The book provides insights into everyday life around the world as people battled with containing the pandemic and explores the broader historical, social, cultural and political contexts in which these responses have developed. COVID-19 is the most serious pandemic to affect the world in the past century. We have all lived in ‘COVID societies’, the long-term effects of which have yet to be experienced or imagined. The COVID crisis has affected countries, regions within countries and social groups within regions in strikingly different ways. These impacts are continually changing, just as the novel coronavirus has mutated into different strains and variants. Throughout the book, a series of intertwined threads cross back and forth between the macropolitical and micropolitical dimensions of COVID-19: contagion, death, risk, uncertainty, fear, social inequalities, stigma, blame and power relations. Overarching these threads are five complementary themes: the historicity of COVID societies; the tension between local specificities and globalising forces; the control and management of human bodies; the boundary between Self and Other; and the continuously changing sociomaterial environments in which the world is living with and through the shocks of the COVID crisis. This book will be of great interest to anyone seeking to understand the manifold complex sociocultural consequences of the COVID-19 pandemic.
