Four hundred and three nasopharyngeal aspirates from hospitalized children have been analysed for RSV, influenza A and B, parainfluenza 3, adenovirus, with Monofluor Kits Diagnostics Pasteur. One hundred and seventeen positive samples were found, RSV: 69, influenza A: 17, influenza B: 12, parainfluenza 3: 2 and adenovirus: 17.
