Researchers at Tufts University’s Cummings School of Veterinary Medicine have identified evidence of SARS-CoV-2 transmission to wildlife and marine mammals, highlighting potential risks of viral spillover and future transmission to humans. Led by Dr. Idrissa Nonmon Sanogo in Dr. Jonathan Runstadler’s laboratory, two studies examined infections and exposure across multiple animal species.
The wildlife study analyzed 1,646 animals representing 29 species in New England and Virginia between 2022 and 2025. Researchers detected active infections in three white-tailed deer, suggesting possible human-to-deer transmission, and evidence of previous exposure in rabbits, coyotes, and raccoons.
A separate study examined 1,017 marine mammals representing 21 species nationwide. Although no active infections were detected, researchers identified antibodies in harbor seals, California sea lions, and grey seals, providing the first evidence of SARS-CoV-2 exposure in U.S. marine mammals. Researchers emphasized continued surveillance to understand transmission patterns, viral evolution, and potential risks to animal and human health.
