Studying Students at Risk for COVID-19

The goal of this longitudinal observational study is to learn about how the COVID-19 has impacted and continues to impact students at the University of Michigan. We hope to determine whether a combination of (1) continuous heart rate obtained from wearable devices, (2) self-reported data from surveys and symptom logs, and (3) saliva samples can be used to help students self-monitor for infection and eventually be able to create a predictive model to detect illness early.

The study was originally intended to last one year, however, it was expanded to follow the study participants over several years. During this study, participants will be asked to: * Provide a baseline self-collected saliva sample * Download and use a suite of mobile apps (e.g., Fitbit, Social Rhythms, Roadmap 2.0) * Complete surveys online * Wear non-invasive Fitbit smartwatch * Grant the study team access to their university academic records (optional) The study will use these tools to monitor participants' physical activity and mental health over the course of at least three years. The study will also examine whether there is a connection between mental health and academic performance.
