Concern grows over new variant in South Africa
A new coronavirus variant has been detected in South Africa that scientists say is a concern because of its high number of mutations and rapid spread among young people in Gauteng, the country’s most populous province, Health Minister Joe Phaahla announced Thursday.
The coronavirus evolves as it spreads and many new variants, including those with worrying mutations, often just die out. Scientists monitor for possible changes that could be more transmissible or deadly, but sorting out whether new variants will have a public health impact can take time.
South Africa has seen a dramatic rise in new infections, Phaahla said.
“Over the last four or five days, there has been more of an exponential rise,” he said, adding that the new variant appears to be driving the spike in cases. Scientists in South Africa are working to determine what percentage of the new cases have been caused by the new variant.
Currently identified as B.1.1.529, the new variant has also been found in Botswana and Hong Kong in travelers from South Africa, he said.
The World Health Organization’s technical working group is to meet Friday to assess the new variant.
The British government announced that it was banning flights from South Africa and five other southern African countries effective Friday, and that anyone who had recently arrived from those countries would be asked to take a coronavirus test.
After a period of relatively low transmission in which South Africa recorded just over 200 new confirmed cases per day, in the past week the daily new cases rapidly increased to more than 1,200 on Wednesday. On Thursday they jumped to 2,465.
