When did you realize Oura could be useful in tracking COVID-19?

“We had a user in Finland who made a public Facebook post in early March, basically saying, ‘I’ve had this ring for a year, I’m an avid athlete, and normally my readiness range is 80 to 90. Then all of a sudden, I woke up one day and my score was 54.’

He was asymptomatic, but he’d been traveling and his body temperature was a degree higher than normal, so he decided to contact the health authorities to get tested. Sure enough, he tested positive.”
