Public Health England (PHE) reported today the total number of cases detected has gone up from 42,323 last week to 75,953 today - an increase of 33,630.
It’s also a five-fold increase from two weeks ago, when the figure was 12,341.
PHE said 99 per cent of new cases are the Delta variant.
Dr Jenny Harries, Chief Executive, UK Health Security Agency said: “Cases are rising rapidly across the country and the Delta variant is now dominant.
“The increase is primarily in younger age groups, a large proportion of which were unvaccinated but are now being invited to receive the vaccine. It is encouraging to see that hospitalisations and deaths are not rising at the same rate but we will continue to monitor it closely. The vaccination programme and the care that we are all taking to follow the guidance are continuing to save lives.
“Please make sure that you come forward to receive both doses of the vaccine as soon as you are eligible. Don’t drop your guard- practice “hands, face, space, fresh air” at all times.”
The Delta variant has fast become the most dominant strain in the UK since it first arrived from India in April.
Scientists say the best guess is that it is 60p er cent more transmissible than the Alpha strain, from Kent, and may double the risk of being admitted to hospital.
But research has shown that vaccines do still prevent hospitalisation from the strain by more than 90 per cent.

It’s put the NHS on a race to give two jabs to as many people as fast as possible, and first doses to the young.
Millions of people still need their first dose, as the PM has pledged to get every adult at least one dose by July 19.
July 19 is the “terminus” date for the end of all Covid restrictions, a delay from June 21 due to the threat of the Delta variant.
