Contact tracing has been shown to be effective in limiting the rate of spread of infectious diseases like COVID-19. Several solutions based on the exchange of random, anonymous tokens between users’ mobile devices via Bluetooth, or using users’ location traces have been proposed and deployed. These solutions require the user device to download the tokens (or traces) of infected users from the server. The user tokens are matched with infected users’ tokens to determine an exposure event. These solutions are vulnerable to a range of security and privacy issues, and require large downloads, thus warranting the need for an efficient protocol with strong privacy guarantees. Moreover, these solutions are based solely on proximity between user devices, while COVID-19 can spread from common surfaces as well. Knowledge of areas with a large number of visits by infected users (hotspots) can help inform users to avoid those areas and thereby reduce surface transmission. This thesis proposes a strong secure system for contact tracing and hotspots histogram computation. The contact tracing protocol uses a combination of Bluetooth Low Energy and Global Positioning System (GPS) location data. A novel and deployment-friendly Delegated Private Set Intersection Cardinality protocol is proposed for efficient and secure server aided matching of tokens. Secure aggregation techniques are used to allow the server to learn areas of high risk from location traces of diagnosed users, without revealing any individual user’s location history.

Contact tracing was deployed widely during the COVID-19 pandemic to attempt to stop the spread of SARS Co-V-2. This dissertation investigates the research on contact tracing from a scientometric perspective and looks qualitatively at how case investigators and contact tracers conducted public health practice during the pandemic. Through approaching the public health practice of contact tracing from both a broad, top-down angle, and an on the ground experiential approach, this dissertation provides insight into the issues facing contact tracing as a public health tool.

Being prepared to respond to difficult situations that arise in public health practice is an essential skill for the public health workforce.This empathic responding guide was designed to train students, volunteers, and staff of the ASU COVID-19 Case Investigation Team. The guide provides an overview of empathic communication, walks through a framework for responding with empathy, and outlines common difficult situations that arise in public health along with ways to respond with empathy to these situations. This guide can be adapted to a wide variety of settings and is meant to be used as a training tool for public health case investigators and other staff. This guide, available in a full and an abridged version, can be paired with hands-on workshops to provide engaging continuing education opportunities for public health teams.

This communication guide outlines examples of specific situations that are difficult to respond to, and pairs them with examples of how to respond with empathy. This guide depicts these difficult case statements as rows with bold, italic text. Beneath each scenario is an example of an empathic response (underlined) that can lead to a factual response or survey prompt (Figure 1). The responses use empathic communication to show the case that you are witnessing the emotion, rather than moving to the survey without acknowledging emotion. There is no one right answer to any difficult case statement.
