Philip D. Murphy, New Jersey • Second week of March, students and school employees, no longer be required to wear masks. • This is not a declaration of victory as much as an acknowledgment that we can responsibly live with this thing • Reverse zoonosis to deer • https://www.nytimes.com/2022/02/07/he... • https://www.biorxiv.org/content/10.11... • Full PDF • https://www.biorxiv.org/content/10.11... • White-tailed deer (Odocoileus virginianus) • Highly susceptible to infection by SARS-CoV-2 • Multiple reports of widespread spillover from humans to free-living deer • SARS-CoV-2 B.1.1.529 Omicron variant • Staten Island, New York, December 12th 2021 to January 31st 2022 • White-tailed deer opportunistically sampled on Staten • 19 of the 131 (14.5%) were positive for SARS-CoV-2 • P.C.R. testing, n = 68 deer • Seven actively infected at the time of sampling • Specific serum antibodies indicating prior exposure • (? Omicron or previous) • Whole-genome sequencing identified Omicron (n = 4) • Circulating amongst the white-tailed deer on Staten Island • Phylogenetic Omicron sequences clustered closely with sequences recovered from infected humans in New York • Human to deer spillover • Urgent need for comprehensive surveillance of susceptible animal species, • to identify ecological transmission networks • • and better assess the potential risks of spillback to humans • Virus may be evolving to adapt to the new host • Infected with earlier variants • Arkansas, Illinois, Kansas, Maine, Massachusetts, Minnesota, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania, Tennessee and Virginia • (Deer have appeared asymptomatic when infected with earlier variants)
