South African scientists have detected a new Covid-19 variant in small numbers and are working to understand its potential implications, the NICD said on Thursday.
The National Institute for Communicable Diseases (NICD) said in a statement that 22 cases of variant B.1.1.529 had been recorded following genomic sequencing, reports Reuters.
"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," the statement quoted the NICD's Professor Adrian Puren as saying.
South Africa was the first country to detect the Beta variant last year. Beta is one of only four labelled "of concern" by the World Health Organisation (WHO) because there is evidence that it is more transmissible and vaccines work less well against it.
The country detected another variant, C.1.2, earlier this year, but it has not displaced the more common Delta variant and still only accounts for a relatively small percentage of genomes sequenced.
