Observational Study Model = Other [non-treatment; impact on external location (rooms and surfaces)]~Time Perspective = Other [viral load samples taken at various time points after nebulization or MDI administered]~Sampling Method = Non-probability sample [to be described by study team]
A randomized, 2-period crossover, single-center, open-label study for viral sample collection. After initiation of inhaled therapy with nebulizer or MDI, cascade impactors and surface samplers will be used to assess viral loads in rooms of subjects with COVID-19.
