New York State COVID-19 Testing Data with County-Level Metrics

New York State's dataset on COVID-19 testing results, beginning March 1, 2020. It is published by the New York State Department of Health via the Electronic Clinical Laboratory Reporting System (ECLRS) and is updated daily on a three-day reporting lag. The data includes daily positive test counts and case rates per 100,000 population for PCR and antigen tests.

Use Cases

• Compare PCR and antigen test positivity rates using Cases Per 100k PCR and Cases Per 100k Antigen.
• Analyze county-level outbreak severity using Geography Description and Total Cases Per 100k (7-day avg).
• Track weekly case rate trends using Total Cases Per 100k and its 7-day average from 10 available columns.

Strengths

• Data collection is mandated by the New York State Sanitary Code, ensuring systematic reporting.
• Includes multiple standardized metrics for comparison, such as cases per 100k for PCR and antigen tests.
• Updated daily with a documented three-day lag for result consolidation.
