Abstract

In a population-based survey of adults in New York City, we assessed positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests (including via exclusive at-home testing) and possible cases among untested respondents. An estimated 27.4% (95% confidence interval [CI]: 22.8%-32.0%) or 1.8 million adults (95% CI: 1.6-2.1 million) had SARS-CoV-2 infection between 1 January and 16 March 2022.
