SARS-CoV-2 occurrence in cervids in the United States and US territories

SARS-CoV-2 was found in multiple cervid species throughout the United States from October 2021 through October 2023 and results reinforce findings of considerable viral spillover from people to cervids. Data demonstrate changes in viral and neutralizing antibody prevalence over time and as well as viral variants that differed from what was circulating in human populations. Continued monitoring can help pinpoint what is driving changes in prevalence and how those changes alter risk to both wildlife and human populations.
