Baldachin: Ceiling HEPA-filtration to Prevent Nosocomial Transmission of COVID-19

In this study, a patient space occupied by a patient with confirmed COVID-19 in an open-space multiple bed area in the Intermediate Care Unit will be equipped with a mobile, optimally placed high efficiency particulate air ("HEPA")-equivalent air filtration unit ("Baldachin") in addition to existing hospital policy infection prevention and control measures. The investigators are going to evaluate this intervention regarding its capacity to prevent the nosocomial onwards transmission of Sars-COV2 to patients located in the same multiple-bed open space patient area.

Inclusion Criteria:Adult inpatients of included open-space IMC units with lab-confirmed SARS-CoV-2 infection, symptom onset or date of test ≤10 days prior inclusion.Exclusion Criteria:Pregnancy, unability to give consent (e.g. informed consent form not available in patient language or non-judicious)
