Covid cases remain significantly high, and there are also concerns about the prevalence of new Covid variations in the UK.
Eleven cases in the Bristol area have been identified as the variant that originally arose in Kent, but are now showing the E484K mutation.
A cluster of 32 cases in Liverpool also have the same mutation but relate to the original strain of coronavirus that has been around since the start of the pandemic.
The South African Covid variant, which also shows the mutation, is under investigation in at least eight postcode areas of England where cases not related to travel have been found.
