Viruses in community-acquired pneumonia in children aged less than 3 years old: High rate of viral coinfection.

摘要: The occurrence of viral coinfections in childhood pneumonia has received little attention, probably because suitable detection methods have been lacking. Between November 2004 and October 2006, the presence 14 respiratory viruses children aged less than 3 years old with community-acquired were investigated using molecular or immunochromatographic techniques and/or culture. A total 315 (338 episodes) included, hospitalization was required 178 episodes. At least one virus detected 66.9% episodes simultaneous two more frequent (27% detection). most frequently syncytial (n = 67: 33 subgroup A, B, 1 not typed), followed by human bocavirus 48), rhinovirus 46), metapneumovirus 39: 13 genotype A2, 8 B1, 5 B2, A1, 12 genotyped) parainfluenza 38: type 1, 2, 22 3, 11 4 typed). found coinfections, which months. Except for adenovirus, incidence low, percentage coinfection ranged between 28.2% 68.8%. Children hospital admission those single infection. It is concluded that are can be a poor prognostic factor.
