The results obtained confirmed the early hypothesis of a faster transmission of the virus from person to person.

Scientists urged colleagues around the world to use the information received to better prepare for the increase in the number of coronavirus infections.
Earlier in Britain, a geneticist from University College London, François Ballou, said that every day about thousands of people, which is significantly higher than the statistics.
