Data are presented as number (% of samples). Total exceeds 100% because of the detection of more than one virus per sample.
RSV, respiratory syncytial virus; RV, rhinovirus; AdV, adenovirus; EV, enterovirus; hMPV, human metapneumovirus; IV, Influenzavirus; hBoV, human bocavirus; CoV, coronavirus; PIV, para‐influenzavirus; PeV, parechovirus.
IV‐B, PIV type 1,2, and 4 were not detected and not mentioned in this table.
