(2002) Incidence and risk factors of RSV-related hospitalizations in premature infants in Germany. Risk factors Some people, including premature babies born before week 32 of pregnancy and infants under 3 months of age, are more at risk of developing severe symptoms from bronchiolitis. Infants younger than 3 months of age are at greatest risk of getting bronchiolitis because their lungs and immune systems aren't yet fully developed.

Results: bronchiolitis due to adenovirus (odds ratio = 49, 95% confidence interval = 12-199) and the need for mechanical ventilation (odds ratio = 11, 95% confidence interval = 2.6-45) were strongly and independently associated with increased risk for bronchiolitis obliterans. Major risk factors for RSV bronchiolitis hospital-ization include: pre-term delivery, severe underlying cardiac, respiratory or neuromuscular disease, and immunodeficiency [6]. Unfortunately, some patients with severe clinical BOS may not show histologic evidence of obliterative bronchiolitis on biopsy, whereas others with significant histologic evidence of BO may be asymptomatic. It usually only occurs in children less than two years of age.

Risk factors for sequelae include severe disease (prolonged stay, ICU admission, ventilation, evidence of hypercarbia, x-ray appearances) and specific infections (especially adenovirus). Recurrent bronchiolitis or persistent respiratory symptoms can also be an indication of underlying issues. Methods. Bronchiolitis is a viral illness seen most commonly during the winter season.
