The Covid-19 Delta variant, which is also known as B1.617.2 and was first identified in India, accounts for 99% of new coronavirus cases in the UK, according to the latest data from Public Health England (PHE).

At least 33,630 cases of the Delta variant were identified in the week to 14 June, bringing the UK’s total number of cases of the variant to 75,953, PHE said on Friday.

As of Monday, a total of 806 people have been hospitalized with the Delta variant, an increase of 423 since last week, the report said.

The new data suggests that both the Oxford Astra/Zeneca and Pfizer/BioNTech coronavirus vaccines are about 75 percent effective in preventing hospitalization from the Delta variant after a single dose and 94% effective after two doses.

Dr. Jenny Harries, Chief Executive of the UK Health Security Agency, warned on Friday that cases of the Delta variant were “rising rapidly” in the UK and that the 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,” she added.
