Weekly Respiratory Virus Deaths in the United States

Provisional data from the National Vital Statistics System tracks the weekly share of U.S. deaths attributed to COVID-19, influenza, and RSV. The dataset's three columns—week_end, pathogen, and percent_deaths—allow for direct comparison of mortality burden across these three major respiratory viruses. Its presence on multiple government platforms indicates its use for public health surveillance and near-real-time trend analysis.

Use Cases

• Tracking weekly mortality trends for a specific pathogen using week_end and pathogen.
• Comparing the relative burden of COVID-19, influenza, and RSV over time using percent_deaths and week_end.
• Identifying peak weeks for virus-specific mortality by analyzing percent_deaths against week_end.
• Assessing the co-circulation impact of multiple viruses by filtering and comparing percent_deaths by pathogen.

Strengths

• Provides a direct, standardized metric (percent_deaths) for comparing three major viruses.
• Data is sourced from the authoritative National Vital Statistics System (NVSS).
• Updated frequently, with last updates recorded in April 2026 across platforms.

Limitations

• Data is provisional and subject to revision; final counts are not included.
• Metadata conflicts exist: one platform lists an 'other-license-specified', while others show no license.
• Key metadata like row count, total size, and detailed documentation are unavailable across all sources.
