Joint statement on the prioritization of monitoring SARS-CoV-2 infection in wildlife and preventing the formation of animal reservoirs
By Food and Agriculture Organization (FAO), World Organisation for Animal Health (OIE) and World Health Organization (WHO)
As we enter the third year of the pandemic, SARS-CoV-2, the virus that causes COVID-19, is spreading between people at an intense level globally. There are many factors that are driving transmission. One of these is the emergence of highly transmissible variants of concern, the latest being Omicron. The virus continues to evolve and the risk of future emergence of variants is high.
Although the COVID-19 pandemic is driven by human-to-human transmission, the SARS-CoV-2 virus is also known to infect animal species. Current knowledge indicates that wildlife does not play a significant role in the spread of SARS-CoV-2 in humans, but spread in animal populations can affect the health of these populations and may facilitate the emergence of new virus variants.
In addition to domestic animals, free-ranging, captive or farmed wild animals such as big cats, minks, ferrets, North American white-tailed deer and great apes have thus far been observed to be infected with SARS-CoV-2. To date, farmed mink and pet hamsters have been shown to be capable of infecting humans with the SARS-CoV-2 virus and a potential case of transmission between white-tailed deer and a human is currently under review.
