Covid-19 testing in Bristol is being ramped up after a mutated form of the Covid-19 variant first found in Kent was confirmed in the city.
Health Secretary Matt Hancock confirmed there were 11 coronavirus cases involving 'mutations of concern' in Bristol.
Now Bristol City Council has confirmed investigations are under way to understand if this mutated form of the virus has spread further in the area.
Christina Gray, Director of Public Health for Bristol, told ITV News the cases have been confirmed in Bristol and South Gloucestershire.
The council says plans for extra testing will be shared once approved.
Christina Gray said: “These new cases have been identified following the proactive sequencing work carried out by colleagues in Public Health England.
"Their early detection of this mutated form of the virus that first appeared in Kent means we can respond swiftly to ramp up testing in the area to better understand the local situation.
"We’re already working with colleagues in health agencies to identify the additional testing we need and how best to deliver this effectively. When plans are ready it will be vital that everyone who is asked to take a test does so promptly.
“Whilst this news will raise concerns and bring uncertainty for many, it remains true that everyone must continue to follow national guidance and lockdown rules.
"We must continue to do the most we can to prevent the transmission of this virus by washing our hands, wearing our masks, avoid mixing socially with people outside of our household and self-isolating when needed.
"These are the behaviours that will protects us and each other from this virus.
“We will continue to draw up plans for additional local testing and share this information when it is ready. In the meantime I urge everyone to focus on their own behaviours and continue to follow public health guidance.”
