Two linked cases of the new Omicron coronavirus variant have been detected in Britain connected to travel to southern Africa, health minister Sajid Javid said Saturday.

Omicron, dubbed a “variant of concern” Friday by the World Health Organization, is potentially more contagious than previous variants of the disease, although experts do not know yet if it will cause more or less severe COVID-19 compared to other coronavirus strains.

 

“Late last night, I was contacted by the UK Health Security Agency. I was informed that they have detected two cases of this new variant, Omicron, in the United Kingdom,” Javid said in a broadcast clip.

 

Essex County Council later confirmed on Twitter there was a single case identified in Brentwood in the southeastern region of England. The council said it was linked to a single case from Nottingham in central England involving travel to South Africa.

 

“We are working with regional and local public health officers who are assessing the situation. All close contacts of these individuals will be followed up and requested to isolate and get tested,” the council said.  

 

The health ministry said two individuals and all members of their households were being re-tested and told to self-isolate while further testing and contact tracing was done.

 

England also will add Malawi, Mozambique, Zambia and Angola to its travel “red list” from 0400 GMT Sunday, meaning British and Irish residents who arrive in the country must quarantine in a government-approved hotel for 10 days.

 

Non-residents will be refused entry. That list already contained Botswana, Eswatini, Lesotho, Namibia, South Africa and Zimbabwe.

 

Prime Minister Boris Johnson and the Chief Scientific Adviser Patrick Vallance and Chief Medical Officer Chris Whitty will hold a news conference later on Saturday “to set out further measures,” Javid said.
