(a) Trend line of the amount of nucleic acids in clinical samples extracted from masks according to each collection day (n = 19). (b) Comparison of Ct values for target genes using clinical samples extracted from masks on each collection day. (c) Comparison of the amount of nucleic acids extracted from throat swabs, saliva, and masks. (d) Comparison of Ct values for target genes using clinical samples extracted from different samples.
