ABSTRACT

Objective. The principal aim was to investigate the viral etiology of lower respiratory infections in children hospitalized in two winter seasons.
Method. One hundred and one children hospitalized with lower respiratory infections were tested by a indirect immunofluorescence technique for respiratory syncytial virus (RSV) parainfluenza, adenovirus and influenza virus, using nasopharyngeal aspirates. Also it was studied the risk severity in infants below 3 months age and those born prematurely.
Results. Virus was identified in 31cases (30.7%). The most frequent were: RSV, with 19 cases (61.3%), after 9 parainfluenza (29.0%), 2 adenovirus (6.5%), and 1 influenza (3.2%). In patients up 3 months old, there was trend toward more severe disease. Bronchopulmonary dysplasia was found in 5 patients, 3 required intensive care and the mean days of hospitalization was 14.7 vs 4.35, from 12 cases without dysplasia in intensive care unit.
Conclusions. Respiratory syncytial virus was principal viral agent detected. The patients younger than 6 months and gestational age less than 35 weeks had more hospital days. Children with bronchopulmonary dysplasia and infants below 3 months old are at risk for severe illness.
