Infants with CF (n=31, samples n=561); healthy infants (n=32, samples=712).
Total number of samples n(%); % of samples refer always to total number of samples: in infants with CF, n=561 (100%); in healthy infants, n=712 (100%).
*Nasal swabs with viral detection irrespective of symptoms.
†Nasal swabs with viral detection and respiratory symptoms. For this analysis, samples with more than one virus were excluded.
ADV, adenovirus; CF, cystic fibrosis; hBoV, human bocavirus; HCoV, human coronavirus; hMpV, human human metapneumovirus; hPeV, human parechovirus; hPIV, human parainfluenzavirus; HRV, human rhinovirus; RSV, respiratory syncytial virus.
