“Our team recognized that COVID-19 was going to be a long-term health care problem, and we knew that wearable devices and smartphones would be a good way to develop digital biomarkers that could determine a COVID-19 infection,” said Shaw. “One of our goals is to expand our data collection capabilities, which will increase our ability to differentiate the COVID-19 infection from other illnesses. This differentiation is going to be key, as we expect to see waves of resurgence pop up as the country opens back up, and some of these flare-ups may coincide with flu season.”



In the first phase of CovIdentfy, the team launched the website, which allows participants to input their relevant demographics and medical information. Delivered via text or email, the daily survey asks participants about people they’ve been in contact with and about specific symptoms if they feel sick. Participants are also asked to share biometric data from their smartphones and smartwatches. The team then matches the biometric data with answers from the survey questions to use the relationship between reported symptoms and any changes in the biometric data to develop biomarkers.


To ensure that they’re also pulling data from a variety of sources and communities, the team developed a plan to target recruitment of people that have a higher risk of contracting the disease, including delivery drivers, grocery store workers, hospital cleaning and cafeteria staff and nurse aids. They are also exploring how they can deploy watches in high-density housing like nursing homes, college dorms, military barracks and homeless shelters.

Study sponsors are supplying devices to people in these key populations who would not otherwise be able to afford a wearable device. The team also is ramping up their targeting efforts in locations outside of the United States where viral hotspots have been identified.



“If CovIdentify is successful, it will be a non-invasive and accessible tool that can help us control the spread of the coronavirus,” Dunn said. “This expanded support brings this goal closer to becoming a reality, and we’re grateful for the support from Duke and from our partners in industry.”
