Shots:

• In May’2020- Fitbit has launched its COVID-19 study to build an algorithm that detects COVID-19 before symptoms starts. The study has enrolled 1000+ positive patients across the US and Canada is now delivering its first- preliminary results 90 days later
• The study demonstrated that its devices could detect ~50% of COVID-19 cases one day before participants reported the onset of symptoms such as fever- cough- or muscle aches
• The algorithm is under development and worked with 70% specificity- or a 30% rate of false positives. The study reinforces that breathing rate- resting heart rate and HRV are all useful metrics for indicating onset of illness and are best tracked at night- when the body is at rest
