New Delta Sub-variant Rising in UK
A new variant of the Delta coronavirus strain thought to account for 6 per cent of all new UK cases is being closely monitored by scientists.
Sub-variant AY. 4.2 could be 10 to 15 per cent more infectious than the original Delta variant that was first spotted in India in December and has become the dominant Covid-19 strain.
Francois Balloux, director of the University College London Genetics Institute, published an analysis on Twitter suggesting that the data implied it was “intrinsically more transmissible”.
He said that research showed AY. 4.2 could be the most infectious variant of the virus to date. It is expected to be placed under investigation by the World Health Organisation.
