COVID-19 Case Surveillance: Patient-Level Clinical and Demographic Data

U.S. COVID-19 case data shared with the CDC, containing 12 elements per patient record. The dataset includes demographics, exposure history, disease severity indicators, outcomes, and underlying medical conditions. Data collection from certain jurisdictions was discontinued in 2023-2024, and the dataset is no longer updated as of July 2024.

Use Cases

• Analyze hospitalization and ICU admission rates using `hosp_yn` and `icu_yn` across `age_group` and `sex`.
• Model mortality risk using `death_yn` as a target variable with predictors like `medcond_yn` and `age_group`.
• Track case progression timelines by comparing `onset_dt`, `pos_spec_dt`, `cdc_case_earliest_dt`, and `cdc_report_dt`.
• Examine demographic disparities in case outcomes using `race_ethnicity_combined`, `age_group`, and `current_status`.

Strengths

• Contains 12 structured data elements per case, including clinical outcomes and demographics.
• Data is sourced from the CDC's national case surveillance system.
• Available in multiple machine-readable formats (CSV, JSON, XML, RDF).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias as several U.S. states discontinued reporting in 2023-2024.
• Some data cells are suppressed to protect individual privacy.
