Abstract

This is a cross-sectional descriptive study aimed to assess the epidemiological characteristics of severe bronchiolitis in children with respiratory syncytial virus (RSV) and explore factors associated with severe infection. A total of 344 patients with bronchiolitis due to RSV were enrolled into the study. Among these, 121 children were classified as having mild-moderate infection and 223 were classified as having severe infection. All patients were treated at the Respiratory Center, National Children's Hospital. Most (86.3%) of children were under 12 months old, and those under 3 months old accounted for 42.7%. The male:female ratio was 2.01:1. The number of cases of bronchiolitis associated with RSV infection were high in the summer, with May registering the highest prevalence with 47 patients, which accounted for 13.6% of the study’s patients. Risk factors associated with severe bronchiolitis were being under 6 months of age, premature birth, birth weight less than 1500 grams, having underlying medical conditions, and bacterial co-infections.
