Researchers are working to see if Garmin watches and other wearable health devices can detect coronavirus. At least three groups are conducting studies."Yeah, we can tell that people are getting sick," said Chris Peng, co-founder of Physio-Q, a nonprofit based in Boston.Consumer products designed to track health and wellness may help researchers detect COVID-19 and stop the spread of disease."We launched this thing within the last month. I don't know if you can tell, I'm pretty tired. We haven't slept in a long time. We're just trying to get this out as soon as possible," Peng said.People opt in to the studies. Researchers are focused on a few key data points to detect COVID, such as resting heart rate, increase in sleep, decline in activity and oxygen saturation levels."The more good data there is available, the better these researchers will be able to do it--refining the algorithms to detect COVID-19," said Sean McNamara, of Garmin.The question scientists want to answer is whether they can determine COVID-19 from the flu or a cold."The more people who participate though, the sooner we can get the better results," said Jessilyn Dunn, of Duke University.It's one way people might know if they have it without going to the hospital or if a test isn't readily available."Contributing your data is one way where you can really get involved, really help out and really make an impact," Dunn said. You don't need a smart watch to opt in. While each study is different, they all aim at stopping the spread of illness now and in the future.Researchers at Duke University say anyone willing to participate in their study can get up to a 50% discount on a new device. That begins next week.
