Geographic access to United States SARS-CoV-2 testing sites highlights healthcare disparities and may bias transmission estimates.

Abstract

We paired high-resolution travel-time metrics with a SARS-CoV-2 testing location database in the United States. Median travel time to testing sites is longer in counties with lower population density, and a higher percent of minority and uninsured individuals. Differential geographic accessibility to testing can recapitulate healthcare disparities and bias transmission estimates.
