App Detects Abnormal Vital signs

Dr. Jaques Reifman, Director, Biotechnology High Performance Computing Software Applications Institute (BHSAI) at the Telemedicine & Advanced technology Research Center (TATRC) https://www.tatrc.org, at Ft Detrick, realizes that early detection of exposure to pathogens from biological weapons or emerging infectious diseases is critical for maintaining military and population health.

The TATRC team developed the 2B-Healthy app to use for automated real time detection of abnormal vital signs. A malaria infection challenge was chosen to study because it has established clinical signs to detect automated real time model with a well- defined time course and symptoms of infection, direct clinical and military relevance, a long incubation period that allows time to make predictions, and early and late stage diagnostic tests approved by FDA.

This study used wearable technology such as a Samsung Gear  S3 smartwatch to collect continuous vital sign data from volunteers, and the data wirelessly was transmitted to the Samsung Galaxy S8 smartphone.

Consisting of commercial-off-the-shelf  hardware and customized software, the 2B-Healthy app pairs a non-invasive wearable device that continuously collects vital sign data with a proprietary algorithm to identify physiological changes associated with abnormal events including infections.

The successful development of the 2B-Healthy app enables the U.S military to carry out automated rapid detection for service member infections including SARS-CoV-2 infected individuals before they can infect others. This is essential to maintaining readiness during the current pandemic as well as future ones.
