COVID-19 Outcomes by Testing Date for New York City Residents

A dataset from the City of New York, last updated on March 22, 2026, showing confirmed cases, hospitalizations, and deaths for cohorts defined by specimen collection date. Outcomes are linked to the date of the initial positive test specimen, not the date of subsequent events like hospitalization. The data is provided as an alternative view to a separate dataset that tracks events by their actual diagnosis, admission, or death dates.

Use Cases

• Modeling the progression from positive test to severe outcomes based on specimen collection date.
• Analyzing hospitalization rates for different testing cohorts over time.
• Estimating case fatality rates for groups defined by their date of specimen collection.
• Comparing outcome timelines between this specimen-date cohort dataset and the event-date dataset referenced in the description.

Strengths

• Data is provided by the City of New York, an authoritative source for local public health information.
• The description clearly explains the cohort definition and links to a comparable dataset for context.
• Available in multiple machine-readable formats including CSV, JSON, and XML.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
