An Epidemic Model With Time Delays Determined By The Infectivity And Disease Durations, Masoud Saade, Samiran Ghosh, Malay Banerjee, Vitaly Volpert

Journal Articles

We propose an epidemiological model with distributed recovery and death rates. It represents an integrodifferential system of equations for susceptible, exposed, infectious, recovered and dead compartments. This model can be reduced to the conventional ODE model under the assumption that recovery and death rates are uniformly distributed in time during disease duration. Another limiting case, where recovery and death rates are given by the delta-function, leads to a new point-wise delay model with two time delays corresponding to the infectivity period and disease duration. Existence and positiveness of solutions for the distributed delay model and point-wise delay model are proved. …

An Age-Dependent Immuno-Epidemiological Model With Distributed Recovery And Death Rates, Samiran Ghosh, Vitaly Volpert, Malay Banerjee

Journal Articles

The work is devoted to a new immuno-epidemiological model with distributed recovery and death rates considered as functions of time after the infection onset. Disease transmission rate depends on the intra-subject viral load determined from the immunological submodel. The age-dependent model includes the viral load, recovery and death rates as functions of age considered as a continuous variable. Equations for susceptible, infected, recovered and dead compartments are expressed in terms of the number of newly infected cases. The analysis of the model includes the proof of the existence and uniqueness of solution. Furthermore, it is shown how the model can …

Overlooked Sex And Gender Aspects Of Emerging Infectious Disease Outbreaks: Lessons Learned From Covid-19 To Move Towards Health Equity In Pandemic Response, Lynn Lieberman Lawry, Roberta Lugo-Robles, Vicki Mciver

Journal Articles: Epidemiology

Sex and gender issues are especially important in emerging infectious diseases (EIDs) but are routinely overlooked despite data and practice. Each of these have an effect either directly, via the effects on vulnerability to infectious diseases, exposures to infectious pathogens, and responses to illness, and indirectly through effects on disease prevention and control programs. The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the viral agent of coronavirus disease 2019 (COVID-19) has underscored the importance of understanding the sex and gender impacts on pandemics. This review takes a broader looks at how sex and gender impact vulnerability, exposure risk, and treatment and …

Participants were recruited from a single independent school for students with neurodiversity and special learning needs, where they had high exposure to computer-/internet-assisted learning. Twenty-seven students responded to questionnaires measuring preferred learning modes, personality traits, and learning engagement. Despite teacher reports …

Could Cultures Determine The Course Of Epidemics And Explain Waves Of Covid-19?, Md Salman Rahman

Theses and Dissertations

Coronavirus Disease (COVID-19), caused by the SARS-CoV-2 virus, is an infectious disease that quickly became a pandemic spreading with different patterns in each country. Travel bans, lockdowns, social distancing, and non-essential business closures caused significant economic disruptions and stalled growth worldwide in the pandemic’s first year. In almost every country, public health officials forced and/or encouraged Nonpharmaceutical Interventions (NPIs) such as contact tracing, social distancing, masks, and quarantine. Human behavioral decision-making regarding social isolation significantly impedes global success in containing the pandemic. This thesis focuses on human behaviors and cultures related to the decision-making of social isolation during the pandemic. …

An Epidemic Model With Time-Distributed Recovery And Death Rates, Samiran Ghosh, Vitaly Volpert, Malay Banerjee

Journal Articles

A compartmental epidemiological model with distributed recovery and death rates is proposed. In some particular cases, the model can be reduced to the conventional SIR model. However, in general, the dynamics of epidemic progression in this model is different. Distributed recovery and death rates are evaluated from COVID-19 data. The model is validated by the epidemiological data for different countries, and it shows better agreement with the data than the SIR model. The time-dependent disease transmission rate is estimated.

Epidemiology In Higher Education: Scarlet Fever At Gettysburg College, Addison E. Lomax

Student Publications

Throughout the early 20th century, the relationship between higher education and the spread of epidemic disease evolved in the United States. Two notable epidemics of scarlet fever in 1915 and 1920 serve as a lens through which the larger roles of disease and higher education can be analyzed. By assessing the roles both the administration and the students played at Gettysburg College, then Pennsylvania College, historians can understand the process of combating health crises in the future. Although the Pennsylvania College scarlet fever epidemics of 1915 and 1920 impacted campus to a smaller extent than the 2020 COVID-19 pandemic, the …

Spatial Epidemiology: An Empirical Framework For Syndemics Research, Shikhar Shrestha, Cici X C Bauer, Brian Hendricks, Thomas J Stopka

Journal Articles

Syndemics framework describes two or more co-occurring epidemics that synergistically interact with each other and the complex structural social forces that sustain them leading to excess disease burden. The term syndemic was first used to describe the interaction between substance abuse, violence, and AIDS by Merrill Singer. A broader range of syndemic studies has since emerged describing the framework's applicability to other public health scenarios. With syndemic theory garnering significant attention, the focus is shifting towards developing robust empirical analytical approaches. Unfortunately, the complex nature of the disease-disease interactions nested within several social contexts complicates empirical analyses. In answering the …

Epidemics and Pandemics: that changed the public health history

Abstract

Currently, the world is experiencing one of the most disruptive pandemics in the modern history of disease and illness. As human beings became more civilized, started building cities, establishing trade routes between cities and countries, the conditions needed for these diseases to spread were greatly enhanced and hence history has recorded many more epidemics and pandemics since the advent of global travel. Many of these epidemics and pandemics have disrupted the life of common human being from BC 430(Athens Plague) until date (Covid 19). Most of the recorded epidemics in …

Mathematical Models Of Covid-19, Kate Faria

Honors Program Theses and Projects

For more than a year, the COVID-19 pandemic has been a major public health issue, affecting the lives of most people around the world. With both people’s health and the economy at great risks, governments rushed to control the spread of the virus. Containment measures were heavily enforced worldwide until a vaccine was developed and distributed. Although researchers today know more about the characteristics of the virus, a lot of work still needs to be done in order to completely remove the disease from the population. However, this is true for most of the infectious diseases in existence, including Influenza, …

A Call To Action: Preventing Opioid And Substance Abuse In South Florida Youth, Julie A. Jacko, Katherine P. Cohen, Cathaerina Appadoo, Arkene S. Levy, Timothy F. Page, Michael J. Parker, Solina Pierre-Gilles, Francois Sainfort

HCA Healthcare Journal of Medicine

The opioid crisis poses a substantial threat to youth throughout the nation. This crisis has been exacerbated by the COVID-19 pandemic, reversing some of the positive national trends in the fight against the opioid epidemic. Some risk factors for youth opioid use have been identified nationally. The South Florida tri-county region of Miami-Dade, Broward and Palm Beach is a culturally distinct region which may not follow national trends and likely has unique risk and protective factors. To address the concerning spike in youth opioid use in South Florida, a community coalition was formed to identify factors unique to South Florida …

Journal Articles: Epidemiology

BACKGROUND: The importance of infectious disease epidemic forecasting and prediction research is underscored by decades of communicable disease outbreaks, including COVID-19. Unlike other fields of medical research, such as clinical trials and systematic reviews, no reporting guidelines exist for reporting epidemic forecasting and prediction research despite their utility. We therefore developed the EPIFORGE checklist, a guideline for standardized reporting of epidemic forecasting research.

METHODS AND FINDINGS: We developed this checklist using a best-practice process for development of reporting guidelines, involving a Delphi process and broad consultation with an international panel of infectious disease modelers and model end users. The objectives …

Journal Articles: Epidemiology

After the Zika virus (ZIKV) epidemic in the Americas in 2016, both Zika and dengue incidence declined to record lows in many countries in 2017-2018, but in 2019 dengue resurged in Brazil, causing ~2.1 million cases. In this study we use epidemiological, climatological and genomic data to investigate dengue dynamics in recent years in Brazil. First, we estimate dengue virus force of infection (FOI) and model mosquito-borne transmission suitability since the early 2000s. Our estimates reveal that DENV transmission was low in 2017-2018, despite conditions being suitable for viral spread. Our study also shows a marked decline in dengue susceptibility …

Human Movement Sciences & Special Education Faculty Publications

In the realm of socioenvironmental justice, much discourse centers on equal access to green areas and on climate injustice in the United States. Marginalized communities, including Indigenous populations, are being excluded from current narratives surrounding the natural spaces that in many cases are historically tied to under-represented groups. This article aims to explore some of the many dimensions of environmental racism, green inequities, climate injustice, and access. The dimensions include but are not limited to racial gatekeeping, nature deprivation in low-income communities, green gentrification, light pollution, and access to clean water. The recommendations section serves as a guide during decisionmaking …

Sars-Cov-2 Viral And Serological Testing When College Campuses Reopen: Some Practical Considerations, Isaac Chun-Hai Fung, Chi-Ngai Cheung, Andreas Handel

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

The coronavirus disease 2019 (COVID-19) pandemic prompted universities across the United States to close campuses in Spring 2020. Universities are deliberating whether, when, and how they should resume in-person instruction in Fall 2020. In this essay, we discuss some practical considerations for the use of 2 potentially useful control strategies based on testing: (1) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase-polymerase chain reaction (RT-PCR) testing followed by case-patient isolation and quarantine of close contacts, and (2) serological testing followed by an “immune shield” approach, that is, low social distancing requirements for seropositive persons. The isolation of case-patients and …
