    Newer study of 875 Fitbit-wearers shows Fitbits detect lasting changes after COVID-19

One in five Americans uses a Fitbit, Apple Watch or other wearable fitness tracker. And over the past year, several studies have suggested that the devices — which can continually collect data on heart rates, body temperature, physical activity and more — could help detect early signs of COVID-19 symptoms.

Now research suggests that these wearables can also help track patients’ recovery from the disease, providing insight into its long-term effects.

In a paper published Wednesday in the journal JAMA Network Open, researchers studying Fitbit data reported that people who tested positive for COVID-19 displayed behavioral and physiological changes, including an elevated heart rate, that could last for weeks or months. These symptoms lasted longer in people with COVID than in those with other respiratory illnesses, the scientists found.

“We want to kind of do a better job of collecting long-term symptoms so we can compare the physiological changes that we’re seeing with symptoms that participants are actually experiencing,” Radin said. “So this is really a preliminary study that opens up many other studies down the road.”

    Apple Launches Study into Whether Apple Watch Can Detect COVID-19 (Other devices could do so too if they did the research)

Apple is launching a study into whether the Apple Watch can be used to detect respiratory illnesses such as coronavirus or flu, in partnership with the University of Washington and the Seattle Flu Study.

A previous independent study by Mount Sinai researchers found that an Apple Watch can effectively predict a positive COVID-19 diagnosis up to a week before current PCR-based nasal swab tests, which may be reinforced by the findings of this new study.

Enrolment is open now for individuals in the greater Seattle area who are age 22 or older and have an Apple ‌iPhone‌ 6s or newer.

Most of the results coming out now for diabetes and atrial fibrillation are based around algorithm detections based on HRV, heart rate, oxygen levels, etc so nothing groundbreaking or new, it's just a question of doing the research which Apple is doing for their device. I had a Fitbit which clearly, in retrospect, showed my sharply elevated resting heart rate about 3 days before I was hospitalised with a viral infection, but the software gave no warning and I only saw it when I was analysing the data manually afterwards. I sold the Fitbit and bought an Apple Watch...
