Public health advice
Covid-19 variant of concern
We are currently working with the Public Health England (PHE) South West Health Protection team to investigate a cluster of cases in Bristol and South Gloucestershire of Covid-19. These have been identified as the Kent variant of the virus (variant of concern VOC202012/01) and also have the E484K mutation.
Some of the cases in the cluster are linked, and further testing and public health investigations are underway.
In line with the announcement made by the Secretary of State today, we will be working with PHE colleagues and partners in Bristol City Council to determine how best to enhance investigations in the local area to understand more about the transmission of the virus and its behaviour and any further control measures required.
For now, our advice remains the same: the best way to stop the spread of the virus is to observe social distancing and abide by the restrictions in place. Whilst in lockdown, it is important that we stay at home unless it is absolutely essential to go out. This includes working from home if you can.
