Weekly U.S. COVID-19 State-Level Cases and Deaths (Archived)

United States state-level aggregate counts of COVID-19 cases and deaths, archived after the end of the public health emergency. The dataset was compiled by the CDC from jurisdictional reports and received a final historical reconciliation update in June 2023. It contains daily time series records for each state and territory up to May 10, 2023.

Use Cases

• Analyze temporal trends in `new_cases` and `new_deaths` by `state` to model disease waves.
• Compare cumulative impact across states using `tot_cases` and `tot_deaths` columns for the covered `start_date` to `end_date` period.
• Study reporting lags and data corrections by examining `new_historic_cases` and `new_historic_deaths` fields.
• Validate state-level pandemic models using the daily time-series structure and CDC-validated case counts.

Strengths

• Data validated through a CDC overnight review process with jurisdictions.
• Contains daily time-series records for all U.S. states and territories.
• Final historical reconciliation was performed for records through May 10, 2023.

Limitations

• Dataset is archived and not updated after June 2023, missing recent developments.
• Counts may not match other archived CDC datasets due to differences in state vs. county source aggregation.
• Probable case and death counts are not separated from totals in this version.
