A coronavirus epidemic hit East Asia 20,000 years ago

A coronavirus epidemic hit East Asia 20,000 years ago A coronavirus epidemic hit East Asia 20,000 years ago NYT News Service | Jun 28, 2021, 05:18 IST (Picture for representation) Researchers have found evidence that a coronavirus epidemic swept east Asia some 20,000 years ago and was devastating enough to leave an evolutionary imprint on the DNA of people alive today. The new study suggests that an ancient coronavirus plagued the region for many years, researchers say. The finding could have dire implications for the Covid pandemic if it s not brought under control soon through vaccination. It should make us worry, said David Enard, an evolutionary biologist at the University of Arizona who led the study, which was published on Thursday in Current Biology. Until now, researchers could not look back very far into the history of this family of pathogens.

Coronavirus epidemic similar to Covid-19 hit East Asia 20,000 years ago

A coronavirus epidemic broke out in the East Asia region more than 20,000 years ago, similar to the current Covid-19 pandemic, an international study of human genomes has discovered. The study found that the outbreak left traces in the genetic makeup of people from East Asia, an area that is now China, Japan, Mongolia, North Korea, South Korea, and Taiwan, said the researchers from the Queensland University of Technology, University of Adelaide, the University of California San Francisco, and the University of Arizona. The modern human genome contains evolutionary information tracing back tens of thousands of years, like studying the rings of a tree gives us insight into the conditions it experienced as it grew, said Professor Kirill Alexandrov from CSIRO-QUT Synthetic Biology Alliance.

We Found Traces of Humanity s Age-Old Arms Race with Coronaviruses Written in our DNA

A coronavirus may have swept across East Asia more than 20,000 years ago. A coronavirus may have swept across East Asia more than 20,000 years ago, leaving traces in the DNA of people in modern China, Japan and Vietnam. Our research, published in Current Biology, found evidence of genetic adaptation to the coronavirus family of viruses in 42 genes in modern populations in these regions. The COVID-19 pandemic, caused by the coronavirus SARS-CoV-2, is so far responsible for more than 3.8 million deaths and billions of dollars in economic losses worldwide. The coronavirus family also includes the related MERS and SARS viruses, both of which have caused significant deadly outbreaks in the past 20 years.
