Apple Watch and Fitbit trackers detect early COVID-19

The Apple Watch and Fitbit watches can detect Covid-19 before symptoms appear. These trackers are able to measure health data such as heart rate and respiratory rate which are among the earliest indicators of virus infection. These smart watches can alert potential COVID-19 patients even before the first physical symptoms.

Finally, smart tech is contributing in fighting against the COVI-19. The Apple Watch and Fitbit trackers can become new weapons in the healthy crisis. When a person is infected with the coronavirus, changes appear in his body, even before the symptoms they experience such as fever, cough, headache, etc. An unexplained increase in heart rate, for example, is one of the first warning signs.

Scientists are studying the possibility of using trackers and smartwatches as tools to aid in the diagnosis of covid-19. Their contribution would be all the more decisive as by alerting users to a potential infection, they can self-isolate and get tested early in order to reduce the risk of spread.

Apple Watch can detect early signs of covid-19 up to 9 days before symptoms

In order to assess the importance of the Apple Watch and activity trackers in diagnosing the coronavirus, a team from Stanford University School of Medicine led by Professor Michael Snyder enrolled 5,000 people in a study. The historical data collected by the tracker of 31 users who tested positive for Covid-19 was analyzed. Of the 31 cases, 80% had data on their devices that indicated infection at or before the onset of symptoms. Signs were detected at or before the onset of symptoms (average three days).

In one of the patients, Snyder’s team discovered that his smartwatch detected the first sign of Covid-19 infection nine days before more obvious symptoms appeared, knowing that the incubation period may go up to two weeks and that many patients are completely asymptomatic while remaining contagious.

In the same respect, Fitbit is conducting its own research on how its activity trackers could help in the early detection of Covid-19. “We saw changes in respiratory and heart rates, which we expected,” said Conor Heneghan, head of the company’s research team. Other scientists around the world are carrying out similar studies.

The promising results of several university studies on the Oura Ring connected ring, for example, prompted the American National Basketball League to buy 2,000 copies of this connected object. NBA players and club staff must now wear it to closely monitor their heart rate and temperature.
