Genome study reveals East Asian coronavirus epidemic 20,000 years ago

An international study has discovered a coronavirus epidemic broke out in the East Asia region more than 20,000 years ago, with traces of the outbreak evident in the genetic makeup of people from that area.

In the past 20 years, there have been three outbreaks of epidemic severe coronaviruses: SARS-CoV leading to Severe Acute Respiratory Syndrome, which originated in China in 2002 and killed more than 800 people; MERS-CoV leading to Middle East Respiratory Syndrome, which killed more than 850 people, and SARS-CoV-2 leading to COVID-19, which has killed 3.8 million people.

But this study of the evolution of the human genome has revealed another large coronavirus epidemic broke out thousands of years earlier.

"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," Professor Alexandrov said.
