Preliminary U.S. COVID-19 Burden Estimates with Weekly Ranges Since 2024

Weekly preliminary estimates of cumulative U.S. COVID-19 burden, including illnesses, outpatient visits, hospitalizations, and deaths, since the start of the 2024 respiratory season. The dataset provides lower and upper estimate ranges for each metric, updated weekly as new hospitalizations are reported to the CDC from the COVID-NET surveillance system. Data is sourced from data.cdc.gov and was last updated on April 3, 2026.

Use Cases

• Analyze trends in COVID-19 burden over time using the Date and Season columns.
• Compare the range of uncertainty in estimates by analyzing the High and Low columns for each Burden type.
• Model the relationship between different burden metrics (e.g., hospitalizations vs. deaths) using the Burden column categories.

Strengths

• Provides weekly updates, with the last update recorded on 2026-04-03 15:58:03.
• Includes both lower and upper estimate ranges (High and Low columns) for each burden metric, quantifying uncertainty.
• Covers multiple burden metrics (illnesses, outpatient visits, hospitalizations, deaths) in a single dataset.

Limitations

• Data are explicitly labeled as preliminary and subject to change, which may affect analysis stability.
• Row count and dataset size are unknown, limiting suitability assessment for large-scale processing.
• Rates for recent hospital admissions are subject to reporting delays, with previous rates updated weekly.
