Submission: November 16, 2022;Published: December 02, 2022


A total of 49 COVID-19 positive cases were included and 17 out of them were selected randomly and monitored after 5 days to compare the availability of the virus based on Ct values of the genes (N and ORF1ab) in nasopharyngeal swabs, saliva and throat swabs. This study states that the best place to collect samples for COVID-19 diagnosis is the nasopharyngeal but saliva can be used in the diagnosis within the first 5 days in people who suffer from health problems that prevent taking a nasopharyngeal swab.
