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.
