One of the most difficult problems in confronting the coronavirus is that a huge number of diseases are asymptomatic. Or people confuse them with something else and end up in the hospital with an already advanced disease. Early diagnosis is an extremely effective control measure, and to this end, the Oura smart ring was developed at the University of West Virginia (USA) in cooperation with the Rockefeller Institute of Neurobiology.
Oura is a set of sensors in a ring-shaped body for constant wearing and monitoring convenience. The ring tracks heart rate, temperature, breathing rate, sleep quality. The data is sent to the cloud AI for processing, which checks it against the patterns of infected people. After the virus enters the body, its incubation begins and Oura's task is to recognize the signs of this process before the virus takes hold and begins destructive activity.
Tests have shown that the ring is capable of detecting signs of infection with a 90% probability three days before the first symptoms of the disease appear. This means that out of 1000 people being scanned, a hundred people may go unnoticed by carriers of the virus. On the other hand, this same limiter does not allow relying on Oura as a reliable coronavirus detector, and therefore other verification and prevention methods cannot be canceled.
Currently, Oura rings are distributed to doctors who work with patients, as well as everyone involved in their transportation, maintenance, etc. The rings act as analogs of personal dosimeters for workers in the nuclear industry, which must be constantly carried with them as a signaling device, without neglecting other safety measures. COVID-19 will not go anywhere anytime soon, and therefore any means of warning about the disease will be extremely in demand.
