Wearable Trackers Could Spot COVID Early

WEDNESDAY, June 22, 2022 (HealthDay News) -- Could your smartwatch know you have a COVID infection before you do? It might be possible one day.

New research suggests that wearable activity trackers that monitor the changes in your skin temperature, heart and breathing rates, combined with artificial intelligence, could be used to identify an infection days before the symptoms start.

The findings were based on a tracker called the Ava bracelet, which is a regulated and commercially available fertility tracker that monitors breathing rate, heart rate, heart rate variability, wrist skin temperature, blood flow and sleep quantity and quality.
