Could your Fitbit or Apple Watch detect early COVID-19 symptoms?

Fitbit and other wearable devices typically linked to exercise are being studied as ways to identify people who are potentially infected with COVID-19 before symptoms appear, when they can unknowingly spread the disease.

Changes in heart rate, respiratory rate, and other biometrics measured constantly by the devices may flag the early stages of virus infection, so an otherwise healthy-looking person knows to self-isolate and seek a COVID-19 diagnostic test, researchers say.

“When you get ill, even before you know it, your body starts changing, your heart rate goes up,” said Professor Michael Snyder of Stanford University School of Medicine.
