Weekly COVID-19 Cases Among Healthcare Personnel

CDC data.cdc.gov provides archived weekly counts of COVID-19 cases among healthcare personnel. The dataset includes weekly case counts, percentages of known healthcare worker status, and MMWR week identifiers. It was last updated in February 2025.

Use Cases

• Analyze temporal trends in healthcare worker infections using the week_end_date and case_count columns.
• Assess data completeness over time by tracking the perc_hcw_known column.
• Align case data with standard epidemiological reporting periods using the MMWR_week and year fields.
• Identify periods of high infection burden among healthcare personnel by aggregating case_count by week_start_date.

Strengths

• Data is structured with weekly granularity via week_start_date and week_end_date columns.
• Includes a metric for data quality assessment via the perc_hcw_known column.

Limitations

• Dataset is archived, indicating it is no longer actively updated.
• Sample data and total row count are unavailable for assessing scale.
• Rows contain cases with missing date fields, complicating time-series analysis.
