  • As of March 16, 2022, Nevada has shifted to weekly reporting on Wednesdays.

October 30, 2020


  • On October 30, 2020, our data source for test data, the Covid Tracking Project, changed its definition of the contents of its totalTestResults field for Nevada. We use this data for our positivity calculation denominator. This will will likely reduce the state's positivity percentage because people are deduplicated people less frequently, resulting in a bigger denominator.

October 15, 2020


  • On October 15, 2020, Nevada switched from reporting tests in specimens to reporting tests in test encounters, and also stopped reporting negative tests (people). This caused the negative test numbers in our source data to freeze. It has temporarily been corrected in the source data, and will alter the percent positivity for October 15-20 the next time the site is updated.
