If you get a COVID-19 infection, a wearable device may be able to alert you. A smartwatch can track how symptoms progress, according to a study from the University of Michigan.
COVID-19’s effects were compared to other parameters collected from heart-rate data in this study. This approach could potentially be used to detect other infections like influenza and the common cold at home or in situations where medical resources are few, such as during a pandemic or in underdeveloped nations.
The University of Michigan researchers discovered that new signals encoded in heart rate indicated when people were infected with COVID-19 and how sick they became while tracking students and medical interns across the country.
They noticed, for example, that after the onset of symptoms, people with COVID-19 had an increase in heart rate per step. People who reported a cough as one of their COVID-19 symptoms, on the other hand, had a significantly higher heart rate per step than those who did not.
