Weekly Hospital Admissions for COVID-19, Flu, and RSV by U.S. Jurisdiction

Weekly hospital admission rates and categorical risk levels for three major respiratory viruses are reported for national and state-level jurisdictions. Data from the CDC's National Healthcare Safety Network (NHSN) are updated every Friday, reflecting admissions from acute care and critical access hospitals. Each row includes counts, rates per 100,000 population, and CDC-defined admission levels for COVID-19, influenza, and RSV.

Use Cases

• Compare weekly admission rates (totalConfC19NewAdmPer100k, totalConfFluNewAdmPer100k, totalConfRSVNewAdmPer100k) across jurisdictions to identify regional outbreak hotspots.
• Analyze temporal trends of admission levels (totalConfC19NewAdmPer100kLevel, totalConfFluNewAdmPer100kLevel, totalConfRSVNewAdmPer100kLevel) using the weekEndingDate column.
• Correlate raw admission counts (totalConfC19NewAdm, totalConfFluNewAdm, totalConfRSVNewAdm) with population-adjusted rates to understand reporting density.

Strengths

• Data is sourced directly from the CDC's National Healthcare Safety Network, a primary U.S. healthcare reporting system.
• Includes three distinct metrics—counts, population-adjusted rates, and categorical risk levels—for each of three viruses.
• Updated weekly with a clear update schedule, with the last update recorded on 2026-05-22.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description notes that previously published data are not revised, which may lead to inconsistencies if reporting is incomplete in early weeks.
• Data for specific jurisdictions like American Samoa were noted as unavailable for certain reporting periods, indicating potential gaps.
