RESUMO
The proportion of asymptomatic carriers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains elusive and the potential benefit of systematic screening during the SARS-CoV-2-pandemic is controversial. We investigated the proportion of asymptomatic inpatients who were identified by systematic screening for SARS-CoV-2 upon hospital admission. Our analysis revealed that systematic screening of asymptomatic inpatients detects a low total number of SARS-CoV-2 infections (0.1%), questioning the cost-benefit ratio of this intervention. Even when the population-wide prevalence was low, the proportion of asymptomatic carriers remained stable, supporting the need for universal infection prevention and control strategies to avoid onward transmission by undetected SARS-CoV-2-carriers during the pandemic.

The emergence of the novel coronavirus or severe acute respiratory syndrome coronavirus 2 leads to a high number of cases of severe pneumonia. So far, little is known about the course of the disease and its symptoms, complications and treatment. We report the first two cases of the syndrome of inappropriate antidiuresis complicating COVID-19 pneumonia.
