Prof Neil Ferguson says India variant may be 30-100% more transmissible than the Alpha variant
The Delta variant of coronavirus is 30% to 100% more transmissible than the previously dominant variant, Prof Neil Ferguson has warned, as the number of daily reported Covid cases exceeded 6,000 for the first time since March.
In one of a number of signs of a third wave, Office for National Statistics data suggested infection levels in England rose by about 75% in a week, with 85,600 people thought to have had Covid in the week ending 29 May – or one in 640 people – compared with 48,500 the week before.
