Cost-Effectiveness Analyses Of Typhoid Interventions In Epidemic And Endemic Settings, Maile Thayer Phillips

Yale Graduate School of Arts and Sciences Dissertations

Background: Typhoid fever is a major source of morbidity and mortality in developing countries, accounting for approximately 12-21 million infections, 119,000-269,000 deaths, and 2-23 million disability-adjusted life years (DALYs) annually. Typhoid fever is caused by infection with the bacteria Salmonella enterica serovar Typhi, which is mainly transmitted through fecal contamination of food or water. Due to these modes of transmission, most cases occur in low- and middle-income countries (LMICs) where sanitary conditions are poor and access to clean water and sanitation is not common. However, the scale of disease incidence is uncertain. Studies suggest that facility-based laboratory-confirmed estimates, the numbers …

Understanding Pandemic Contact Tracing From A Design Thinking Perspective, Nancy K. Lankton, Avinandan Mukherjee, Kaustav Mukherjee

Accounting Faculty Research

Because of its highly infectious nature and ability to spread from non-symptomatic people, pandemics can bring society and businesses to a standstill and death to hundreds of thousands of people across the world. Public health experts point to four Ts in successful epidemiological control, namely, test, trace, track, and treat. Since COVID-19 has no effective treatment, contact tracing has been a vital part of COVID-19 disease control and focuses on identifying and isolating people who have come into contact with individuals who have tested positive for the disease. Early surveys show that individuals are not comfortable with all contact tracing …

Reinvigorating A Technical Countering Weapons Of Mass Destruction Distance Learning Graduate Certificate Program, James C. Petrosky, Gaiven Varshney, Jeremy Slagley, Sara Shaghaghi

Faculty Publications

Current Countering Weapons of Mass Destruction (CWMD) demands can be divided broadly into policy and science. The science of chemical, biological, and radiological/nuclear weapons informs the limits of development, production, employment, operation, detection, risk characterization, human and material protection, and medical intervention. In short, the science of weapons of mass destruction (WMD) should precede and inform the development of policy. It is to this end that the Air Force Institute of Technology (AFIT) CWMD program was re-established, providing a technical educational option for practitioners to understand the science behind a very technically challenging subject.

Recognition And Screening For Chagas Disease In The Usa, Rachel Marcus, Andres F. Henao-Martinez, Melissa Nolan Ph.D., Mph, Elizabeth Livingston, Stephen A. Klotz, Robert H. Gilman, Monica Miranda-Schaeubinger, Sheba Meymandi

Faculty Publications

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a public health concern, mainly among countries in South and Central America. However, despite the large number of immigrants from endemic countries living in the USA, awareness of CD is poor in the medical community, and therefore it is significantly underdiagnosed. To avoid the catastrophic cardiac complications of CD and to prevent maternal–fetal transmission, widespread educational programs highlighting the need for diagnosis are urgently needed.

School-Based Sex Education In The United States And Its Association With Sexual And Reproductive Health Outcomes, 2000-2020, Priscilla M. Lopez

Dissertations and Theses

Background: There are significant sexual and reproductive health disparities in the United States (US). A significant proportion of sexual health disparities among adolescents is likely due in-part to inadequate school-based sex education. Sex education encourages sustainable and informed sexual behavior and has the potential reach adolescents prior to sexual debut and throughout the years at highest risk for adverse sexual health outcomes. However, the way in which sex education is defined and operationalized, as described in the literature, varies substantially, which may lead to wide variation in implementation in schools and this might explain the disparities seen. State-level sex …

Department of Paediatrics and Child Health

Background: Selenium (Se), an essential trace mineral, has been implicated in preterm birth (PTB). We aimed to determine the association of maternal Se concentrations during pregnancy with PTB risk and gestational duration in a large number of samples collected from diverse populations.
Methods: Gestational duration data and maternal plasma or serum samples of 9946 singleton live births were obtained from 17 geographically diverse study cohorts. Maternal Se concentrations were determined by inductively coupled plasma mass spectrometry analysis. The associations between maternal Se with PTB and gestational duration were analysed using logistic and linear regressions. The results were then combined using …

A Susceptible Exposed Infected Recovered Susceptible (Seirs) Model For The Transmission Of Tuberculosis, Latifat M Erinle-Ibrahim, Waheed O Lawal, Olukayode Adebimpe, Gbemisola R Sontan

Tanzania Journal of Science

In this paper, a deterministic mathematical model was proposed and analyzed to understand the dynamics of tuberculosis based on the SEIRS model. The disease-free equilibrium, the endemic equilibrium, and their stabilities were examined. The R0 (basic reproduction number) was derived using the Next Generation Matrix method and its sensitivity analysis showed that the birth rate and infectious rate were the most sensitive parameters of R0. The behaviour of exposed individuals at the latent period with varied treatment rates were examined through numerical simulation. From the analysis carried out, the effect of variations of the treatments of latent TB shows that …

Informing Viral Surveillance Of Oropouche Virus: An Emerging Arbovirus, Christine E. Walsh

LSU Master's Theses

Arboviruses are viruses transmitted by hematophagous arthropod vectors. Many of these viruses pose a threat to human health. While some infections may be asymptomatic, others may produce febrile illness, or manifest in life threatening conditions. Symptomatic diagnosis of patients with generalized febrile illness can be confounded due to the various diseases that present clinically in the same manner, and a lack of available diagnostic tests. Surveillance efforts can be used to create awareness about the prevalence of neglected tropical arthropod-borne pathogens, such as Oropouche virus (OROV), and inform preparedness measures for disease outbreaks (SURVEILLANCE SENTENCE). OROV is an arbovirus and …

The Role Of Interspecies Recombination In The Evolution Of Antibiotic-Resistant Pneumococci, Joshua C. D'Aeth, Mark Pg Van Der Linden, Lesley Mcgee, Herminia De Lencastre, Paul Turner, Jae-Hoon Song, Stephanie W. Lo, Rebecca A. Gladstone, Gps Consortium, Sadia Shakoor

Department of Pathology and Laboratory Medicine

Multidrug-resistant Streptococcus pneumoniae emerge through the modification of core genome loci by interspecies homologous recombinations, and acquisition of gene cassettes. Both occurred in the otherwise contrasting histories of the antibiotic-resistant S. pneumoniae lineages PMEN3 and PMEN9. A single PMEN3 clade spread globally, evading vaccine-induced immunity through frequent serotype switching, whereas locally circulating PMEN9 clades independently gained resistance. Both lineages repeatedly integrated Tn916-type and Tn1207.1-type elements, conferring tetracycline and macrolide resistance, respectively, through homologous recombination importing sequences originating in other species. A species-wide dataset found over 100 instances of such interspecific acquisitions of resistance cassettes and flanking …

Are Covid-19 Models Blind To The Social Determinants Of Health? A Systematic Review Protocol, Ava John-Baptiste, Marc S. Moulin, Shehzad Ali

Epidemiology and Biostatistics Publications

Introduction Infectious disease models are important tools to inform public health policy decisions. These models are primarily based on an average population approach and often ignore the role of social determinants in predicting the course of a pandemic and the impact of policy interventions. Ignoring social determinants in models may cause or exacerbate inequalities. This limitation has not been previously explored in the context of the current pandemic, where COVID-19 has been found to disproportionately affect marginalised racial, ethnic and socioeconomic groups. Therefore, our primary goal is to identify the extent to which COVID-19 models incorporate the social determinants of …

Estimating Parameters Of A Seird Model Applied To Sars-Cov-2 Infections In Germany Based On The Particle Swarm Optimization Method, Evandro A. Nakajima, Antonio A. Ignacio, Denise Lange, Erika Izumi

Applied Mathematics & Information Sciences

The present paper describes a particle swarm optimization (PSO) method used to estimate parameters of a Susceptible- Exposed-Infected-Recovered-Dead (SEIRD) model applied to predict SARS-CoV-2 transmission in Germany, based on data from February 15th to April 25th, 2020, considering that the lockdown in the country started on March 23rd. The model estimated patients’ mortality (4.92%) and recovery rates (95.08%), virus incubation (8.54 days), infection periods (18.65 days), as well as the basic virus reproduction number before (R0 = 11.60) and after (R0 = 0.39) lockdown. The predicted values were accurate until the 70th day. The performances achieved by the model were …

Adapting An Agent-Based Model Of Infectious Disease Spread In An Irish County To Covid-19, Elizabeth Hunter, John D. Kelleher

Articles

The dynamics that lead to the spread of an infectious disease through a population can be characterized as a complex system. One way to model such a system, in order to improve preparedness, and learn more about how an infectious disease, such as COVID-19, might spread through a population, is agent-based epidemiological modelling. When a pandemic is caused by an emerging disease, it takes time to develop a completely new model that captures the complexity of the system. In this paper, we discuss adapting an existing agent-based model for the spread of measles in Ireland to simulate the spread of …
