all patients with vascular disorders consecutively admitted at our tertiary care hospital from March 16 to December 07, 2020

data of two nationwide PCR-based studies conducted in a representative random sample, from April 1-6, and November 12-14, 2020, collected by the Austrian Ministry of Science and the Austrian Red Cross to estimate the spread of SARS-CoV-2 infection among the non-hospitalized Austrian population.

HCP worker data, including nurses, nurse technicians, physicians, surgical personal, physical therapists, nurse practitioners, environmental service workers, administrative staff, and dietitians, working in close proximity to admitted patients at our tertiary care hospital from March 16 to December 07, 2020.

Nasal or pharyngeal respiratory swabs were routinely taken of each patient admitted at our departments and repeated regularly at 48 h intervals during the inpatient stay.

In the HCP cohort testing for SARS-CoV-2 RNA was performed, on a weekly basis, at the Department of Laboratory Medicine, Medical University of Vienna, Austria, using real-time polymerase chain reaction (RT-PCR). Comparability of the results of all test methods used was confirmed by participation in international quality control ring trials.

The primary endpoint of the present study was to determine the prevalence of SARS-CoV-2 infection in patients with vascular disease after the implementation of institutional and governmental safety measures and compared it to SARS-CoV-2 infections among the general population in Austria.
