COVID-NET: Weekly COVID-19 Hospitalization Rates by Demographics and State

Weekly rates of laboratory-confirmed COVID-19 hospitalizations collected by the CDC's COVID-NET surveillance network. The data includes demographic breakdowns by age, sex, and race, as well as state-level information and cumulative rates. Data are preliminary, updated weekly, and sourced from the overlapping RESP-NET surveillance areas.

Use Cases

• Analyze temporal trends in hospitalization rates using Week ending date and Weekly Rate.
• Compare demographic disparities in hospitalizations using Age Category, Sex, and Race columns.
• Assess state-level variation in disease burden using the State and Cumulative Rate columns.
• Model seasonal patterns of COVID-19 hospitalizations using the Season and Weekly Rate columns.

Strengths

• Data is sourced from the CDC's official COVID-NET surveillance network, an active, population-based system.
• Includes multiple demographic breakdowns with columns for Age Category, Sex, and Race.
• Provides both weekly and cumulative rate calculations for temporal analysis.
