Rapid Acceleration of Diagnostics - TECH (RADx-TECH): RADx Tech COVID-19 Viral Dynamics/COVID Detect. Rapid Acceleration of Diagnostics - TECH (RADx-TECH): RADx Tech COVID-19 Viral Dynamics/COVID Detect

The COVID Detect/COVID-19 viral dynamics study was planned and performed to assess SARS-CoV-2 viral dynamics in early infection, accuracy/persistence of SARS-CoV-2 antigen/PCR testing, clinical aspects of mild COVID-19, and potential SARS-CoV-2 transmission dynamics or risk factors. We performed a cohort study of adult students and employees of University of Illinois Urbana-Champaign (UIUC) and Northwestern University who tested positive for SARS-CoV-2 as part of campus surveillance programs (isolation participants) or close contacts (particularly roommates) of individuals testing positive for SARS-CoV-2 (quarantine participants). Isolation participants were enrolled within 24 hours of positive testing and quarantine participants were enrolled within 5 days of last known exposure. All... (for more see dbGaP study page.)
