Research: The origin of Covid-19 dates back to 20,000 years – Health News


In a study by scientists in the USA, it was claimed that the traces of the new type of corona virus (Covid-19) were seen in East Asian communities 20 thousand years ago.

According to the study published in the journal Current Biology, it was stated that 20,000 years ago in East Asia, there was an epidemic of Covid-19 that was so effective that it left an evolutionary trace in the DNA of people living today.

In the research, it was noted that the findings showed that the ancient corona virus had been effective in the region for years, indicating that this could have dire consequences if the current Covid-19 epidemic is not controlled with vaccination.

David Enard, an evolutionary biologist from the University of Arizona, who led the study, said: “This should worry us. The current epidemic may continue for generations and generations.”

It was announced that Enard and other scientists involved in the research were investigating the effects on the DNA of people carrying the virus, rather than looking at the genes of existing corona viruses, and it was found that viruses cause enormous changes in the human genome over generations.

“SIGN THAT THEY ARE ADAPTABLE TO ANCIENT CORONA VIRUSES”

In the research, it was pointed out that viruses and humans pass on the mutations they develop against each other to the next generations, emphasizing that scientists examine the human genome within these genetic variation patterns to reconstruct the history of viruses.

It was stated that scientists who found that 42 of these genes have a dominant version in East Asian populations, saw these findings as a strong sign that people in that region were adapted to ancient corona viruses.

In the study, it was estimated that all these genes developed antiviral mutations between 20 and 25,000 years ago, most likely over several centuries, while what is surprising is the question of how the virus spread so much when East Asians, who were hunter-gatherers at the time, did not live in dense communities.
