PRFs with typical symptoms were tested. Cough was present in 667 (88%), fever in 158 (21%), sore throat in 100 (13%), dyspnea in 24 (3%), myalgia in 14 (2%) and anosmia in 2 (0.2%) patients. A total of 344 (45%) tests were carried out in HCWs, including 26 with additional risk factors, while 414 (55%) were carried out in PRFs. The mean age of HCWs was 39 years (±17 years) and 254 (74%) were female. The mean age of PRFs was 49 years (±17 years) and 233 (56%) were female.

In total 44 (5.8%) tests were positive for SARS-CoV-2, 17 (5%) in HCWs and 27 (6.5%) in PRFs. Throughout March 2020 the rate of positive tests increased continuously, correlating with the progress of the COVID-19 pandemic in Switzerland. The highest rate of positive test results was noticed on 30 March with 21% positive results (see Fig. 1 ).

After screening, all persons were initially managed as outpatients, 7 persons with positive test results, 1 HCW and 6 PRFs, needed hospitalization during the course of the disease (0.92%), 6 recovered well, while 1 person is still critically ill and requires intensive care treatment and mechanical ventilation.

The present analysis confirms the rise in prevalence of positive tests correlating with the extent of the COVID-19 pandemic in Switzerland. As expected, cough and fever proved to be the most prominent symptoms. Interestingly, the hospitalization rate in the screening population remained relatively low even though the majority of positive test results occurred in PRFs.
