Respiratory Aerosols in Patients With COVID-19 and Healthy Controls

The proposed study will investigate respiratory aerosols in SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona Virus 2) positive and negative children and adults with the Resp-Aer-Meter (Palas GmbH). For this purpose, first, the measurement of respiratory aerosols (particle sizes and concentration) with the Resp-Aer-Meter will be established. Thereafter, a comparison between polymerase chain reaction (PCR) SARS-CoV-2 positive and negative participants (children and adults) will be conducted. In addition to the measurement of aerosols, the clinical symptoms, lung function (FEV1) and laboratory inflammatory markers will be analyzed.
