Researchers tracked deviations in heart rate and sleep patterns, which tend to change when a person has the flu and compared that data to flu-like illness rates reported by the Centers for Disease Control and Prevention.
This marks the first time heart rate trackers and sleep data have been used to predict the flu or any infectious disease in real time, study authors say.
Twenty percent of children under five and approximately 7% of working adults get the flu each year. It also results in 650,000 deaths annually worldwide.
