A study in the US has found that smartwatches and other wearable fitness devices that continuously measure vital signs of the human body can detect changes in the body 9 days before the coronavirus symptoms set in.

The findings suggest that activity tracking and health monitoring via smartwatches and similar devices may be used for the large-scale, real-time detection of respiratory infections.

The researchers noted that smartwatches and other wearable devices are already used by tens of millions of people worldwide and measure many physiological parameters, such as heart rate, skin temperature and sleep.

They investigated the use of wearable devices for the early detection of Covid-19 in a retrospective manner, and also present an approach for using wearable device-detected physiological parameters for real-time health monitoring and surveillance.

"Using heart rate and steps data from a large cohort of 5,262 individuals, we show that heart rate signals from fitness trackers can be used to retrospectively detect Covid-19 infection well in advance of symptom onset," the authors said.

"In addition, we developed an online detection algorithm to identify early stages of infection by real-time heart rate monitoring," they said?
