Background: Since the COVID-19 pandemic, research of aerosols and their importance for the transmission of SARS- CoV-2 as well as their role in super-spreading events has intensified. The present study compared healthy controls, outpatients with mild SARS-CoV-2 disease (outpatient group) and severely ill hospitalized patients (inpatient group) to investigate the connection between aerosol production and disease severity. Methods: For this purpose, the exhaled aerosol concentration of 234 adults (53 outpatients, 61 inpatients and 120 controls) was analyzed in a prospective clinical trial. The study consisted of a clinical examination, spirometry and aerosol measurement using a spectrometer (Resp-Aer-Meter, Palas GmbH, Karlsruhe, Germany). Results: The outpatients had a milder clinical course, fewer co-morbidities, a.. Read More»
