Exploring barriers to TB contact tracing and screening: health service providers’ perspective
… explore and describe the barriers that impact TB contact tracing and screening efforts from the perspective of healthcare providers, the Ward-based primary health care outreach teams (WBPHCOT). The study followed a qualitative descriptive exploratory design. In-depth interviews were conducted with …

COVID-19 and the decline of autonomy: contact tracing in the age of surveillance capitalism
… new forms of surveillance technology, namely, contact tracing applications. This study examines the long-standing history of surveillance as well as the shifts in public health surveillance with the rise in technologically mediated solutions. In both research and public discourse, the …

The analysis, design, and development of a digital contact tracing prototype application for the identification of passengers in the event of a biological threat scenario onboard an airplane
… Many practitioners and researchers agree that contact tracing represents an important factor in mitigating the global spread of a pandemic. This study aims to explore the analysis, design and development of a ‘contact tracing’ prototype application in relation to (but not limited to) airline …

Impact of lockdown on COVID-19 transmission dynamics in Botswana : a mathematical modeling study.
… lockdown alone as well as in combination with contact tracing. Furthermore, the model was used to estimate the impact of lockdown on reproduction number. According to the model projections, 4362 cumulative confirmed cases would have been recorded after a year in the worst-case scenario of no …

A Secure and Privacy Preserving COVID-19 Notification System
… an effective treatment, there have been various Contact Tracing Systems (CTS) developed and adopted across the globe to help stop the spread of the virus. While people are concerned about their exposure to the virus, they also worry about the breach of privacy inherent to using CTSs due to their …

A complex, high-performance agent-based model used to explore tuberculosis and COVID-19 case-finding interventions
… control. Early diagnosis interventions include contact tracing and isolation, testing of asymptomatic people thought to be at high risk of infection, and in the case of TB, screening using chest X-rays. The impact of several such early diagnosis interventions on case detection have been studied …

Essays in Experimental Economics
… Chapter 1. Here, we study the effectiveness of contact tracing and quarantine programs aimed at containing the spread of infectious diseases, and further investigate the role of political ideology in driving behaviour in the US. Using a dynamic game, we investigate the relative effectiveness of …

ICE-MILK: Intelligent Crowd Engineering using Machine-based Internet of Things Learning and Knowledge Building
… impact of occlusions, mobility and contact tracing, and distancing. In this dissertation, we propose an Intelligent Crowd Engineering platform using Machine-based Internet of Things Learning, and Knowledge Building approaches (ICE-MILK) to enhance the accuracy, scalability, and crowd …

The Local Governance of the 2014 Ebola Epidemic: A Comparative Case Study of Liberia and Sierra Leone
… the health centers. These laws and door-to-door contact tracing were scaled up to a national emergency strategy, relying on traditional leaders to monitor and enforce them. In Liberia, community and traditional leaders organized in many areas to correct some of these demand-side barriers too. In …

Analysis of the Position-Dependent Error in FTM RTT Indoor Navigation
… such as asset tracking, indoor navigation, and contact tracing. Unfortunately, the error of reported FTM RTT distance measurements has been shown to have a standard deviation that ranges from 1-2 meters in ideal setups. A major FTM RTT error source was discovered and coined as the …

Weighted Graph Compression using Genetic Algorithms
… common in areas such as bioinformatics, epidemic contact tracing, social networks, and many others. Graph compression is the process of merging nodes that are highly connected into one super-node, thus shrinking the graph. The goal of graph compression is to merge nodes while mitigating the amount …

Graph-theoretic Approach To Modeling Propagation And Control Of Network Worms
… quarantining, predictive traffic-blocking, and contact-tracing. The analysis of the predictive dynamic traffic-blocking, employing only local information, shows that the worm can be contained so that 40\% of the network nodes are not affected. Finally, we develop the Detection via Distributed …

Rifampicin-resistant Mycobacterium tuberculosis: an emerging threat to human health in Botswana
… such as intensified case finding and targeted contact tracing in identified hotspots, to help halt the transmission of RR-TB strains. Treatment success was high; however, mortality was higher among people living with HIV, which suggests the need for careful monitoring of this population. …

An assessment of the management of sexually transmitted diseases (STDs) in a rural district health ward of Northern Kwazulu
… forms, the spectrum of STD syndromes and the contact tracing rate were assessed. The private sector treated nearly a third of the STDs even though they charge about ten times the price of the public sector services. In general, the clinical skills of all providers were poor. While hypothetical …

High-throughput sequencing to understand pathogen carriage and transmission
… community, complemented with epidemiological and contact tracing data, to determine transmission dynamics. I found that after a limited number of viral introductions into the university, the majority of student cases were linked to a single genetic cluster, likely dispersed across the university …

Recent HIV seroconversion at time of first positive test : a comparison before and after HIV reportability
… diseases on 1 May 2003 which included enhanced contact tracing by public health. A sensitive/less-sensitive (S/LS) algorithm using a modified EIA anti-HIV assay was employed to evaluate enhanced partner notification by comparing the proportion of newly diagnosed cases of HIV presenting within 6 …

From traffic to transmission: adapting an agent-based transport model to simulate the spreading of infectious diseases
… phone data. These patterns are used to identify contacts between synthetic persons. The contacts can be attributed to certain contexts as the MATSim model is activity-based, meaning that different activity types such as work, school or leisure are included in the model. Thus, this serves as a …

Rumor source identification, contagion processes, and dynamics of social network formation and evolution
… bubbles with varying degrees of overlap. In contact tracing contexts, this estimator may be used to identify the source of a local outbreak, which can then be used for forward tracing or for further backward tracing (by similar or other means) to an upstream source. Secondly, we consider …
