The goals of this study are 1) to validate the use of a wearable diagnostic capability and software as a medical device (SaMD) algorithm for the pre or early-symptomatic detection of COVID-19 infection, 2) assess the wearable device on the subjects, and 3) ensure data are collected, securely stored, and easily read and interpreted by non-laboratory personnel.

This is an open label iterative study designed to calibrate the algorithm to maximize its test characteristics. The sample size is derived from the minimum number of COVID-19 subjects required to evaluate algorithm sensitivity and specificity. A sample size of 200 true positive COVID-19 infections is anticipated to assess device predictive analytics. Assuming a six-month enrollment period, a 15 percent patient lost to follow-up rate, and a positive COVID-19 infection rate of 10 percent within the study population, a sample size of 2,352 subjects will be enrolled in this prospective study.

Primary Outcomes: The primary outcomes of interest are performance of the BioSticker multiparameter vital signs wearable and the sensitivity of the BioCloud-based algorithms in detecting early onset of active COVID-19 related signs and symptom in subjects prior to or coincident with a positive COVID-19 diagnostic test and the specificity of the BioSticker algorithms in distinguishing positive diagnosis of infection from negative diagnosis of infection among subjects. COVID-19 infection will be confirmed by both participant affirmation and diagnostic laboratory testing. Additional primary outcome is the intuitive presentation of affirmative diagnostic results from the BioSticker early detection algorithm(s).

Secondary Outcomes: The secondary outcomes of interest include correlation of biometric data indicators to individual-level experiential feedback reported through participant symptom-tracking and diagnostic questionnaires.
