Following contract tracing of the person who is infected with the new variant Omirccon in Brentwood, there has been confirmation the case is linked to a primary school which has around 400 pupils.
England’s first two cases of Omicron were identified on 27 November in Nottingham and Brentwood in Essex.
People who are connected to the primary school in Essex are being urged to get tested.
A statement from Essex council says, “UK Health and Security Agency, Department of Health and Social Care, Larchwood Primary School and colleagues from Essex County Council and Brentwood Council have worked together to take necessary precautionary action to prevent the spread.
“This includes making specialist testing available for all pupils and school staff and confirming arrangements for remote learning for one class.
“We appreciate that this is an unsettling time for parents, pupils and the school community but we take the time to remind everyone that this is a precautionary measure.”
The person who is infected with Omicron is “well” and is isolating with family.
Essex director of public health Dr Michael Gogarty told BBC Breakfast, “Most importantly with the confirmed case is that they are well, they are isolating with their family.
“When I say that they are well, I mean they are not seriously ill.
“They have some symptoms but they do not require hospitalisation.”
