[Value of fast indirect immunofluorescence diagnosis of respiratory viruses].

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. Rapid diagnosis of viral diseases allows to decrease the incidence of nosocomial infections, to watch over infants carrying RSV who might develop severe bronchiolitis. This technique combined with anatomic examination showed that sudden death occurred, in 7 of 15 infants, during an acute respiratory infection (RSV: 6).
