Wearable health AI system aims to detect COVID-19 before symptoms
Human data analytics company Empatica, a spinoff of MIT Media Lab, has announced a partnership with the Biomedical Advanced Research and Development Authority (BARDA) - a U.S. Department of Health and Human Services office - to validate an early warning system for COVID-19 and other respiratory infections using its wearable sensors and proprietary algorithm.

The system, named Aura, is completely noninvasive and uses the company's medical smartwatches, software, and artificial intelligence (AI) capabilities. Aura, says the company, will enable continuous and real-time insight into the likelihood of SARS-CoV-2 infection before symptoms present, and send a warning to the user and their healthcare provider.

Early last year the company and BARDA's Division of Research, Innovation and Ventures (DRIVe) began to develop a digital biomarker that predicts respiratory infections. Preliminary findings, says the company, have been promising, showing a strong correlation between viral shedding and changes in a person's physiology. Now it will be sponsored to run a validation trial specific to early detection of COVID-19.

The aim of the validation trial is to validate the company's algorithm in real-life settings, with the participation of healthcare workers who are exposed to a high viral load while treating hospitalized COVID-19 patients. They will wear the company's E4 medical-grade research wearable wristband for 30 days, during which their physiological data will be reviewed against daily nasopharyngeal (NP) samples and a daily qRT-PCR swab, ensuring the highest ground truth.

"We are very proud to join forces with BARDA to help improve the health and safety of millions of Americans going back to work," says Empatica CEO Matteo Lai. "This product introduces a new paradigm: empowering individuals and institutions with smart health monitoring, so that they will know early when they need to self-isolate and take care of themselves. Without BARDA's leadership and foresight over the past year, our early detection algorithm would not have reached this pivotal stage of clinical validation, which will accelerate our request for FDA's approval of Aura as a medical product for use by people at risk of contracting COVID-19."

BARDA Acting Director, Gary Disbrow, Ph.D.,adds, "We anticipate that access to real-time and actionable health information will empower people to seek medical advice and care sooner, or to adopt behavioral changes such as temporary
