The study reveals that the SARS-CoV-2 delta variant was transmitted from humans to lions at a Singapore zoo, emphasizing the risk to captive and endangered animals. The researchers call for strict infection control measures and suggest vaccinations for susceptible animals to protect them from anthropogenic viral transmissions.
Researchers found that SARS-CoV-2 antigens can persist in the body for up to 14 months after initial infection, challenging the idea that COVID-19 is a transient illness. This finding has implications for understanding long-term effects of the virus and could influence future treatments and vaccines.
