Mortality Associated With Respiratory Syncytial Virus, Bronchiolitis, and Influenza Among Infants in the United States: A Birth Cohort Study From 1999 to 2018.

ABSTRACT:

Background

Infant mortality due to respiratory syncytial virus (RSV) in the United States is not well understood.

Methods

From 1999 to 2018, RSV, bronchiolitis, and influenza deaths were described for infants <1 year using linked birth/death datasets from the National Vital Statistics System. Mortality was described overall and by infant birth and death characteristics. Bronchiolitis was included as the plausible upper limit of RSV, while influenza served as a comparator.

Results

Total infant deaths were 561 RSV, 1603 bronchiolitis, and 504 influenza, and rates were 6.9 (95% confidence interval [CI], 6.4-7.5), 19.8 (95% CI, 18.9-20.8), and 6.2 (95% CI, 5.7-6.8) per 1 000 000 live births, respectively. The highest RSV rates were observed among <29 weeks' gestational ag
