New Delhi, Nov 17 (IANS) Scientists have found SARS-CoV-2 spreads like any other virus among white-tailed deer and other wild animals in the United States, CNN reported.
People are the likely source, but that doesn't mean the virus can't evolve among these animals and then spill back into humans, and researchers are worried about what this spread means for the risk of future pandemics, the report said.
There's little doubt SARS-Cov-2, the virus that caused the ongoing pandemic, came from an animal -- almost certainly a bat. And the prevailing scientific opinion is that there is an intermediate host, an animal of some sort, that was infected by a bat or bats and then infected people, the report added.
It's also clear that people can infect animals. Pets such as cats, zoo animals such as gorillas and snow leopards and farmed mink can all be infected. Multiple cases have been reported, and evidence of changes in the viruses infecting mink have led to mass culls of those animals on fur farms, the report added.
The latest species to capture the attention of wildlife biologists are white-tailed deer. It's little surprise that farmed deer would catch the virus from people. Any visitor to a deer farm knows the animals behave like goats, shoving their wet noses into the pockets, hands and faces of human visitors or caregivers as they clamor for food and treats -- and setting themselves up for infection.
"If somebody might bite an apple and throw it or even if I sneeze in a tissue and drop it," speculated Dr Suresh Kuchipudi of the Animal Diagnostic Laboratory at Pennsylvania State University, who helped lead one study published earlier this month that found a third of deer they tested across Iowa between September of 2020 and January of 2021 showed evidence of infection.
Sewage has been found to carry the virus, so polluted water might be a source, he added, or people spitting or contaminating the environment in other ways. The deer may then spread the virus to one another, the report added.
Six Sikhs were killed in the August 5, 2012, attack in which four people, including a police officer, were injured and one person died last year from the wounds sustained in the shooting.
U.S.-based Novavax partnered with the Serum Institute of India to apply in the three countries, and plans later this month to also seek the World Health Organization review needed to be part of the COVAX global vaccine program.
The Biden administration has kept in place travel restrictions that have severely curtailed international trips to the U.S., citing the spread of the delta variant of the virus. Under the rules, non-U.S. residents who have been to China, the European Schengen area, the United Kingdom, Ireland, Brazil, South Africa and India in the prior 14 days are prohibited from entering the U.S.
The U.S. Centers for Disease Control last week warned the Delta variant of the virus is so contagious, vaccinated people who do get infected could be just as big a risk to others as people who aren't vaccinated.
The new requirement, which will be phased in over several weeks in August and September, is the most aggressive step the city has taken yet to curb a surge in cases caused by the delta variant.
