Scientists find coronavirus outbreak started late 2019

  • Investigators, who analysed virus genomes from over 7,500 infected people, find nearly 200 mutations in the SARS-CoV-2 virus since China’s outbreak but say this does not mean it is getting deadlier.
  • Scientists have found the coronavirus that causes Covid-19 has been in circulation since possibly October last year, evolving ever since it struck China with close to 200 “recurrent genetic mutations” in the virus.
  • The study “Emergence of genomic diversity and recurrent mutations in SARS-CoV-2″ was carried out by a group of international scientists led by University College London.
