Application Description:  


Real time contact tracing and risk monitoring

Full description:

The app is for a research study titled "REACT: Real-time Contact Tracing and Risk Monitoring via Privacy enhanced Mobile Tracking". This study will enroll 3000 people recruited from Emory University, University of Southern California, and University of Texas Health Sciences Center at Houston. The purpose of this study is to evaluate the effectiveness of a privacy preserving mobile application for contact tracing and risk monitoring. The app is intended to monitor and reduce users' individual risks of COVID-19 and influenza-like illness. Additionally, data from this project will support research in how COVID-19 and influenza like illness spread within groups.

If a user downloads the app and elects to participate, she will be asked to register some social demographic characteristics into the application. On a daily basis, she will be asked
to enter response regarding the presence or absence of symptoms of illness. Additionally, aspects of her social networks will be collected. Whenever there is a contact with
another app user, anonymous bluetooth based proximity data and location data (the user can choose privacy level for perturbing the location data) will be collected.
