IIT Delhi study Decodes Evolution of SARS-CoV-2
  • Researchers have revealed the driving mechanisms and evolution of SARS-CoV-2 in humans.
  • This can help in better understanding COVID-19’s immune evasion and the emergence of variants of concern.
  • This seven-member research team found that once cytosine numbers in virus genomes have been linked to host-switching, the virus replication will start and it develops the ability of a virus to cause disease.
  • It is also noted that SARS-CoV-2 genomes rapidly decrease after the first few months of evolution in humans.
  • The depletion of genomes also depends upon particular adaptation to the human host.
  • This research has been done on over 1.4 million full-length SARS-CoV-2 sequences from across the world.
  • These studies will create the groundwork for groundwork for future studies on understanding virus-host interactions with the human body.
