Wearable devices could help detect early signs of COVID-19, heart conditions, study suggests

​Wearable devices that track one's physical activity, such as smartwatches, could help detect early signs of disease, including COVID-19, heart conditions and falls, a new study has suggested. Researchers from the University of South Australia reviewed 28 studies, including 12 lakh participants, and found that smartwatches and activity trackers could correctly identify COVID-19 status in 88 out of 100 people, similar to results from rapid screening tests.
