Ct: cycle threshold; D: collection day of samples included in our series; FA: filmArray RP2.1; HCoV: human coronavirus; LP: low positive; M: membrane gene; N: nucleocapsid gene; Ne: negative; P: positive; PIV3: parainfluenza virus 3; RdRp: RNA-dependent RNA polymerase gene; RSV: respiratory syncytial virus; S: spike gene; 0: none. Not tested: due to insufficient sample volume.
