ABSTRACT
BACKGROUND:
Respiratory syncytial virus (RSV) is the leading cause of hospitalization in US infants. Accurate estimates of severe RSV disease inform policy decisions for RSV prevention.METHODS:
We conducted prospective surveillance for children <5 years old with acute respiratory illness from 2016 to 2020 at 7 pediatric hospitals. We interviewed parents, reviewed medical records, and tested midturbinate nasal ± throat swabs by reverse transcription polymerase chain reaction for RSV and other respiratory viruses. We describe characteristics of children hospitalized with RSV, risk factors for ICU admission, and estimate RSV-associated hospitalization rates.RESULTS:
Among 13 524 acute respiratory illness inpatients <5 years old, 4243 (31.4%) were RSV-positive; 2751 (64.8%) of RSV-positive children had no underlying condition or history of prematurity. The average annual RSV-associated hospitalization rate was 4.0 (95% confidence interval [CI] 3.8-4.1) per 1000 children <5 years, was highest among children 0 to 2 months old (23.8 [95% CI 22.5-25.2] per 1000) and decreased with increasing age. Higher RSV-associated hospitalization rates were found in premature versus term children (rate ratio = 1.95 [95% CI 1.76-2.11]). Risk factors for ICU admission among RSV-positive inpatients included age 0 to 2 and 3 to 5 months (adjusted odds ratio [aOR] = 1.97 [95% CI 1.54-2.52] and aOR = 1.56 [95% CI 1.18-2.06], respectively, compared with 24-59 months), prematurity (aOR = 1.32 [95% CI 1.08-1.60]) and comorbid conditions (aOR = 1.35 [95% CI 1.10-1.66]).CONCLUSIONS:
Younger infants and premature children experienced the highest rates of RSV-associated hospitalization and had increased risk of ICU admission. RSV prevention products are needed to reduce RSV-associated morbidity in young infants.
