Apple Watch can detect symptoms from COVID-19

A new article published today in the JAMA Network Open magazine highlights that even wearable devices like the Apple Watch and Fitbit can anticipate symptoms and provide data on the long-term effects of COVID-19.

As reported by the New York Times, the new data comes from the study Digital Engagement and Tracking for Early Control and Treatment (DETECT) conducted by scientists from the Scripps Research Translational Institute in California. This study lasted from March 25, 2020 to January 24, 2021 and involved more than 37,000 people using Fitbit, Apple Watch, and other wearables.

The researchers determined that the combination of the data collected by Apple Watch (and other devices) with patient self-reported symptoms led to a more accurate detection of COVID-19 cases than monitoring symptoms alone without any help. This means that some wearable devices can help detect COVID-19 symptoms.

Additionally, the researchers focused on long-term health effects for patients affected by the virus, finding that about nine days after the first symptoms are reported, their heart rate has decreased. After this decline, which was not observed in patients with other diseases, their heartbeats increased again and remained elevated for several months. It took an average of 79 days for their resting heart rate to return to normal, compared to just four days for non-COVID-19 positive patients. Sleep levels and physical activities also returned to baseline levels after longer for those affected by the virus.

The study will continue in the coming months to provide more details on what the long-term effects of COVID-19 may be.
