The new variant of the coronavirus, Omicron, has started wreaking havoc all over the world. Its knock has started in India as well. Meanwhile, research of an institution in America has come to the fore. In which it has been revealed that when corona infected humans come in contact with animals and infected animals come in contact with a healthy person, then a new variant can be born. This is called reverse zoonosis. That is, a type like SARS-CoV-2 can arise. Explain that Omicron is a SARS-CoV-2 variant.


The research team at the US College of Veterinary Medicine and Biomedical Sciences analyzed mutation types in the coronavirus after infection in cats, dogs, ferrets, and hamsters. The research was recently published in PNAS, the official journal of the National Academy of Sciences. This research was done on different types of animals like the wild, zoo, and domestic animals. According to research, if an animal comes in contact with a corona-infected human, then a new type of coronavirus variant can be born. This research has strengthened the fact that whether the birth of the Omicron variant is also a part of this process?

According to Lara Bashor, a doctoral student in the Department of Microbiology, Immunology, and Pathology in the US, “In general, many types of viruses cannot infect other species of animals, they have become very specific. But SARS-CoV of the corona family ” -2 is different from that.”

At the same time, Eric Gagne, assistant professor of wildlife disease ecology at the University of Pennsylvania, says, “The virus poses a higher risk to animals living near humans, so it has given the opportunity to generate different variants of the Kovid-19 family.” ,

In fact, a few days ago, scientists made shocking revelations on Omicron, a dangerous variant of the corona found in South Africa. Scientists had claimed that Omicron has reached humans through rodents i.e. animals like rats. This process is called reverse zoonosis.

difference between zoonosis and reverse zoonosis

It can be understood in such a way that when a disease reaches from animal to human, then this process is called zoonosis. At the same time, when the disease from animals changes its form and comes back to humans, it is called reverse zoonosis. The same claim has been made by the scientists in their report. Scientists say that the more mutations found in this variant were not seen in other variants of the corona, because there are 32 mutations in Omicron. However, it still cannot be said with certainty whether Omicron spread from animals or gradually evolved into humans.
