New coronavirus spread swiftly around world from late 2019, study finds | Reuters

Over 7,500 people who had contracted the new coronavirus strain have participated in a genetic study to shed more light on where it spread and how fast it moved across the world. The study has shown that the virus spread faster than previously thought, showing that it had left China between October and December in 2019. The mutated strain, now known as SARS-CoV-2, has been adapting to different hosts as it spread, and over 200 recurrent genetic mutations were found. “Phylogenetic estimates support that the COVID-2 pandemic started sometime around Oct. 6, 2019 to Dec. 11, 2019, which corresponds to the time of the host jump into humans,” commented Francois Balloux in the Infection, Genetics and Evolution journal. This shows that the virus has been mutating from the start and has been infecting people earlier than reports have stated.
