Although the Covid-19 pandemic is driven by human-to-human transmission, Sars-CoV-2 can also infect other animal species. Fearing the emergence of new variants of concern and the formation of animal reservoirs, the World Health Organization (WHO), the Food and Agriculture Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE) published in this Monday, 7, joint statement warning of the need to monitor cases of the disease in wildlife.

The organizations point out that in addition to domestic animals, free-living, captive or farmed wild animals can be infected by the virus that causes covid. So far, they say, farmed mink and pet hamsters have been shown to be able to infect humans with Sars-CoV-2. A possible case of transmission between white-tailed deer, common in North America, and a person is under review.
Even pointing out that wildlife still does not play a significant role in the spread of the virus, institutions warn of the possibility of creating animal reservoirs. That is, for Sars-CoV-2 to establish itself and multiply in the animal and then reach other hosts.
Because of this concern, WHO, FAO and OIE have emphasized the importance of monitoring wild mammal populations and sharing genomic sequencing data in public databases. And, as an emergency measure, suspend the sale of live wild mammals in food markets.
In addition, they highlighted that teams of professionals who work in contact with wildlife implement measures that reduce the risk of transmission, such as the good use of PPE.
They also advised hunters not to chase animals that look sick. However, they said that current evidence suggests that humans do not become infected with the virus by eating meat.
Also, they said that people should not approach or feed wild animals. They must also safely dispose of food scraps, masks and any other human waste to avoid attracting wildlife to urban centers.
