Official title
Asymptomatic and Pre-symptomatic Transmission of SARS-CoV-2 in a Community Congregant Setting: a Study to Understand How Infection Control Practices Can Mitigate Exposure Risks
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall aim of this study is to measure how transmission of COVID-19 occurs in communities - including the role of super spreaders and/or identifying conditions that may increase transmission risk, with a focus on congregant situations. In order to identify how presence of symptoms and behavior affects the transmissibility of the virus, the investigators will measure SARS-CoV-2 in exhaled breath of asymptomatic and symptomatic persons using polyvinyl alcohol (PVA) test strips embedded in face masks (Face Mask Sampling- "FMS") - an innovative, non-invasive method for detection of SARS-CoV-2 in exhaled air.
