We tested coatis (Nasua nasua) living in an urban park near a densely populated area of Brazil and found natural SARS-CoV-2 Zeta variant infections by using quantitative reverse transcription PCR, genomic sequencing, and serologic surveillance. We recommend a One Health strategy to improve surveillance of and response to COVID-19.
Genomic sequencing revealed SARS-CoV-2 Zeta variant infection in wild coatis, confirming viral evolution consistent with spillback from humans in Brazil.
