Delta variant cases double in a week in the ITV Anglia region
The number of cases of the Delta or Indian variant of coronavirus in the Anglia region passed more than 1,100 in the latest weekly figures - an increase of 98%.
Figures from the Wellcome Sanger Institute in Cambridge show there were 1,105 cases of the Delta variant in the week to 5 June in the Anglia region compared with 559 cases during the previous week.
The near doubling of cases in the region follows last week's data which appeared to show the prevalence of the variant has levelled off in Eastern England but now there has been a resurgence.
There is a time lag with the release of data involving the Indian or Delta variant because it takes longer to analyse the genetic make-up of the positive test sample. The variant is now the dominant strain of coronavirus in the region.
The 1,105 cases represented about 60% of the total confirmed cases in the Anglia region in that week.
Overall the rolling weekly total of positive cases in the Anglia region has been rising every day since 22 May compared to the previous seven days.
The rising number of cases and the impact of variants are among the factor being used to decide when the final pandemic restrictions are to be lifted. Another element will be the number of hospitalisations.
The number of Covid-19 admissions to hospitals in the East of England has risen by nearly 50% in the fortnight to 9 June. There were 49 patients in hospital in 11 June which is about the same as September 2020. In January 2021 there were more than 4,000 Covid-19 patients in the region's hospitals.
