*SARS-CoV-2 seropositive fallow deer sampled in February 2022 (n = 21) were PCR negative for the SARS-CoV-2 envelope gene in all samples tested (retropharyngeal lymph nodes, nasopharyngeal mucosa, palatine tonsil, and cecal content). ND, not detected. †SARS-CoV-2 surrogate virus neutralization test was used to determine % neutralizing antibodies in deer serum samples. ‡Begging ranks were occasional or consistent beggars or unranked. Unranked indicates the deer were untagged.
