*
Two different types of HCoVs were co-detected in 18 samples.
†
Due to the samples with ≥2 non-HCoV co-detections, the sum of the number of samples positive for each non-HCoV is greater than the number of samples with any non-HCoV co-detection. RSV, respiratory syncytial virus; RV, Rhinovirus; HAdV, human adenovirus; Flu, influenza; PIV, parainfluenza virus; HBoV, human bocavirus; HMPV, human metapneumovirus.
