A new concerning COVID-19 variant with numerous mutations and could be more contagious has been discovered in South Africa.

South African Health Minister Joe Phaahla on Thursday announced that researchers have identified the variant, currently identified as B.1.1.529, in the country's economic hub, the Gauteng province. The variant has also been found in Botswana and Hong Kong. 

The discovery of the new variant has prompted the World Health Organization’s technical working group to meet Friday to assess the threat posed by the strain. Not much is currently known about B.1.1.529 except that it has several mutations that could impact how it reacts to vaccines.

"We don't know very much about this yet. What we do know is that this variant has a large number of mutations. And the concern is that when you have so many mutations, it can have an impact on how the virus behaves," WHO’s technical lead on COVID-19, Dr. Maria Van Kerkhove, said in a Q&A. 

Van Kerkhove added that researchers are now studying the new COVID-19 variant and what this may potentially mean for "our diagnostics or therapeutics and our vaccines."

As of Thursday, South African health officials have detected the new variant in 22 COVID-19 cases in the country. At least four cases of the new variant were also found in people who are fully vaccinated against the virus.

Health authorities in the United Kingdom have now added South Africa to the country’s “red list” for travelers. All flights going to the six countries in the region have also been canceled.

"More data is needed but we're taking precautions now. From noon tomorrow six African countries will be added to the red list, flights will be temporarily banned, and UK travelers must quarantine," Sajid Javid, the U.K.’s secretary of state for health and social care, announced on Twitter.

Despite the spread of the B.1.1.529 variant, COVID-19 case numbers in South Africa remain well below the figures reported during the country’s Delta surge earlier this year, according to the National Institute for Communicable Diseases.

As of Thursday, South Africa, Eswatini and Zimbabwe are rated as “COVID-19 low,” according to the Center for Disease Control and Prevention’s travel advisory. Namibia is rated as “COVID-19 moderate,” Lesotho as “COVID-19 high” and Botswana as “COVID-19 very high.”
