South African scientists have detected a new COVID-19 variant in small numbers and are working to understand its potential implications, they said on Thursday. 

The variant - called B.1.1.529 - has a "very unusual constellation" of mutations, which are concerning because they could help it evade the body's immune response and make it more transmissible, scientists told reporters at a news conference.

Early signs from diagnostic laboratories suggest the variant has rapidly increased in the most populated province of Gauteng and may already be present in the country's other eight provinces, they said.

South Africa has confirmed around 100 specimens as B.1.1.529, but the variant has also been found in Botswana and Hong Kong, with the Hong Kong case a traveller from South Africa. As many as 90% of new cases in Gauteng could be B.1.1.529, scientists believe.

"Although the data are limited, our experts are working overtime with all the established surveillance systems to understand the new variant and what the potential implications could be," South Africa's National Institute for Communicable Diseases said in a statement.

South Africa has requested an urgent sitting of a World Health Organization (WHO) working group on virus evolution on Friday to discuss the new variant.
