New COVID-19 Data Tracker Website for Laboratories

On Thursday, May 7, 2020, CDC published a new  COVID-19 Data Tracker website. The site consolidates laboratory test results data reported by laboratories in the United States, including public health, hospital, and commercial and reference laboratories. This website displays a variety of laboratory data:

  • Number of tests reported nationally and by state
  • Number of positive tests nationally and by state
  • Percent of laboratory test results that are positive nationally and by state

The data presented are aggregate COVID-19 data reported to CDC from state health departments and territorial jurisdictions. The website explains that the number of positive tests in a state is not equal to the number of cases: one patient can potentially be tested more than once, and not all laboratory tests are reported to CDC.

In the future, this website will include county-level data.

If you have additional questions, please contact CDC’s Emergency Operations Center (EOC) Laboratory Working Group at eocevent405@cdc.gov.
