RSV Risk Factors
There are several risk factors for severe RSV (respiratory syncytial virus) infections that, in some cases, need to be treated by hospitalization. The following risk factors increase a person's chance of developing RSV:
- Premature birth (35 weeks or earlier)
- Low birth weight
- History of asthma
- Attending childcare or daycare
- Congenital heart disease
- Certain lung diseases, such as bronchopulmonary dysplasia
- Drugs or conditions that suppress the immune system
- Household crowding (four or more children in the home)
- Exposure to tobacco smoke
- Being elderly.
