- Development of database containing physiological, behavioral data in combination with SARS-CoV-2 infection [ Time Frame: Through study completion, an average of 7 months ]To develop a database of physiological and behavioral data via wearable devices and self-reported questionnaires (e.g.,symptoms) combined with laboratory confirmation of SARS- CoV-2 infection.
- Correlation between SARS-CoV-2 infection and collected wearable data and self-reported data [ Time Frame: Through study completion, an average of 7 months ]Physiological and behavioral data from wearable devices (Garmin vivosmart 4, Empatica E4) , patient self-reported data questionnaires (includes but is not limited to demographics, symptoms, medical history, lifestyle, comorbidities, and Medical care utilization), and laboratory diagnostic confirmation of SARS-CoV-2 infection.
- Development of analytical models for real-time COVID-19 surveillance at the individual and population levels [ Time Frame: Through study completion, an average of 7 months ]Physiological and behavioral data from wearable devices (Garmin vivosmart 4, Empatica E4) , patient self-reported data questionnaires (includes but is not limited to demographics, symptoms, medical history, lifestyle, comorbidities, and Medical care utilization), and laboratory diagnostic confirmation of SARS-CoV-2 infection.
- Performance of the analytical models for real-time COVID-19 surveillance at the individual and population levels. [ Time Frame: Through study completion, an average of 7 months ]Model performance and accuracy characteristics of the analytical models on hold out data sets
