For the next few years or more, the planet probably won't have enough vaccine for everyone. Even as countries with large COVID-19 vaccination programs start pushing to resume travel and trade:~We will not know who is vaccinated and who is not . We will not know who is an (a)symptomatic COVID-19 carrier and who is not.~Because of this, the global community will remain in various stages of masking, social distancing, lock-down, and limited congregation because of cyclical COVID-19 spikes and people will continue to feel unsafe and afraid as novel COVID-19 variants appear and disappear.~This large-scale, multi-site, multi-national study is informed by a completed pilot study at Johns Hopkins- NCT04556149. This study is designed to validate the ability of the imPulse™ Una infrasound-to-ultrasound e-stethoscope to rapidly and accurately screen outpatients with and without confirmed COVID-19 with sensitivity, specificity, positive and negative predictive value matching (PPA >95%) for early, accurate, and rapid, self-directed and point-of-care diagnosis of COVID-19 in areas still lagging in access to vaccines.
This study generates robust, uniform clinical data across emerging COVID-19 strains to train ML/AI algorithms of the Sponsor's imPulse™ Una infrasound-to-ultrasound e-stethoscope for digital diagnostic feature synthesis of asymptomatic and symptomatic COVID-19 digital biosignatures for rapid and accurate adult and child mass screening.
