LONDON : Scientists in the UK are investigating the impact of a new mutant variant of coronavirus, named VUI-202012/01, on children and whether its faster transmission in parts of England is down to the younger segment of the population.The government's New and Emerging Respiratory Virus Threats Advisory Group (Nervtag) is monitoring the data to analyse this arc of the variant, which has led over 40 countries, including India, to suspend travel to and from the UK in order to try and contain the more infectious mutation.Earlier strains of coronavirus found it harder to infect children than adults, with one explanation being that children have fewer of the doorways called the ACE2 receptor the virus uses to enter a human body's.
