In hospitalized COVID-19 patients, face-mask sampling was used to measure the amount of exhaled SARS-CoV-2

The respiratory pathway is what drives SARS-CoV-2 transmission from person to person, although little is known about the pattern and volume of viral production from exhaled breath. Face-Mask Sampling (FMS), which we have previously demonstrated is capable of detecting exhaled tubercle bacilli, has been modified for use in quantifying exhaled SARS-CoV-2 RNA in patients admitted to hospitals with Coronavirus Disease-2019 (COVID-19).
