“We’ve seen how data has potential to help the healthcare community respond faster to outbreaks - most recently, The Scripps Research Translational Institute published a study that showed data from Fitbit wearables significantly improved the prediction of influenza-like illness.”

A US study of 47,000 Fitbit users, published in The Lancet Digital Health journal and reported by Reuters, found that heart rate and sleep data from wearable fitness trackers can predict and alert public health officials to real-time outbreaks of flu more accurately than current surveillance methods.

Users’ resting heart rate and sleep duration were monitored and flagged as abnormal if the average weekly heart rate was significantly above their overall average and their weekly average sleep was not below their overall average.

“Responding more quickly to influenza outbreaks can prevent further spread and infection, and we were curious to see if sensor data could improve real-time surveillance,” said Jennifer Radin from the Scripps Research Translational Institute.
