A smartwatch can inform about coronavirus infection before the first symptoms of the disease appear, according to US scientists from the Mount Sinai Clinic in New York.


Experts used smartwatches from three different companies to diagnose coronavirus in the early stages. Research has shown that gadgets can detect signs of illness up to a week before symptoms appear.

As part of the experiment, patients were monitored for heart rate variability, which means a change in the intervals between the onset of heart rhythms. As the scientists found out, low variability is a sign of infection with COVID. High variability, on the contrary, can serve as a signal that the body is coping with stress on its own.

The study involved 300 employees of the US clinic who were wearing smartwatches from April 29 until September 29.

NEWS.ru reported earlier that the World Health Organization's (WHO) Independent Pandemic Preparedness and Response Group said the PRC authorities could respond more quickly to the emergence of coronavirus in Wuhan to contain its spread.
