Suara.com – A new study reports that some Russian white-tailed all over Michigan, Pennsylvania, infected corona virus Covid-19. In the bodies of these deer, which were tested from January to March, there are 40% antibodies SARS-CoV-2.
Another, unpublished study, also detected 80% of coronavirus antibodies in deer in Iowa. The tests were conducted between November 2020 and January 2021.
This high infection rate led researchers to conclude that deer transmit the coronavirus to one another. Scientists also identified the presence of other SARS-CoV-2 variants, suggesting that there are multiple infections from humans to deer.
The abundance of white-tailed deer in North America and the fact that these animals often live in close proximity to humans provide several opportunities for disease to move, reports The Conversation.
Water sources contaminated with SARS-CoV-2 are also suspected to be a route of transmission, although this has not been proven.
Transmission from humans to deer and from elk to deer is believed to be driving the rapid spread of the disease in white-tailed deer populations across the US.
This finding has raised concerns that the white-tailed deer could be a reservoir SARS-CoV-2, which not only easily infects large numbers of animals, but can also infect humans.
In addition, the reservoir host is also at risk of giving rise to new coronavirus variants, which can cause greater infection rates, increase symptom severity and can evade the human immune system.
Any reinfection from wildlife reservoirs could also complicate our long-term efforts to combat and suppress Covid-19 in society.
