Parental Socioeconomic Status and an Infant's Risk of Hospital Admission for Respiratory Syncytial Virus.

Background: While clinical risk factors for respiratory syncytial virus (RSV) bronchiolitis are well established, data on socioeconomic risk factors is lacking. We explored the association of parental education, income, and employment status on an infant's risk of hospitalization for RSV bronchiolitis.

Methods: This population-based retrospective case-control study covered all RSV-related hospital admissions of under 1-year-old children in Finland between 2004 and 2018.
