Performance of 3 Sampling Methods for the Detection of SARS-CoV-2 (COVID-19) With Real-time Reverse Transcriptase PCR

Thirty volunteers will be recruited from health care workers suspicious for Covid-19, who consult the ocupational physician for Covid-19 testing. For each volunteer, 3 swabs will be taken: * Flocked eSwab (Copan, Italy) of the oropharynx * Flocked nasopharyngeal eSwab (Copan, Italy) of the nasopharynx * Dry flocked nasopharyngeal Swab, placed in lysis buffer Each swab will be tested for the presence of SARS-CoV-2 with an in-house reverse-transcriptase real-time PCR (Egene). Performance of each method will be calculated.
