Sources & Methods

Frequently Asked Questions

What is RSV and who is most at risk?

RSV (respiratory syncytial virus) is a common respiratory virus that usually causes mild, cold-like symptoms. However, it can be serious for infants, young children, and older adults. RSV is a leading cause of hospitalization in children under 1 year old.

How is RSV activity measured?

This page tracks RSV using hospital admission data from the CDC NHSN system. The metric shown is new RSV-confirmed hospital admissions per 100,000 people per week. This captures the burden on the healthcare system rather than total infections.

How often is RSV data updated?

RSV hospitalization data is updated weekly. The CDC publishes new hospital capacity and admission data each week, typically with a 1-2 week reporting lag.
