A new variant of the coronavirus has been detected in South Africa.

The variant, B.1.1.529, is said to have a high number of mutations, which may be a source of concern in relation to immunity and transmissibility.

Confirming the discovery in a statement on Thursday, the NICD said 22 positive cases of the new variant have so far been detected in the country.

“The National Institute for Communicable Diseases (NICD), a division of the National Health Laboratory Service, confirms that through collaborative efforts with private laboratories and the NGS-SA members, a new COVID-19 variant, B.1.1.529, has been detected in South Africa,” the statement reads.


“Twenty-two positive cases of variant B.1.1.529 have been recorded in the country following genomic sequencing collaborations between the NICD and private laboratories. In addition, other NGS-SA laboratories are confirming more cases as sequencing results come out.”

According to the statement, Adrian Puren, NICD acting executive director, said it is “not surprising” that a new variant has been detected in South Africa.

“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. Developments are occurring at a rapid pace and the public has our assurance that we will keep them up to date,” Puren said.

The institute said Joe Phaahla, the country’s health minister, confirmed that the new variant has also been detected in Botswana and in Hong Kong.

He said the variant was of “serious concern” and behind an “exponential” increase in reported cases, making it “a major threat”.

Michelle Groome, head of the division of public health surveillance and response at the NICD, also said provincial health authorities remain on high alert and are prioritising the sequencing of COVID-19 positive samples.

“This means that individuals should get vaccinated, wear masks, practice healthy hand hygiene, maintain social distancing, and gather in well ventilated spaces. Individual compliance to preventative measures can have a great collective impact in limiting the spread of the new variant,” she added.

As of September 2021, the World Health Organisation (WHO) had identified five COVID variants — Alpha, Beta, Gamma, Delta and Mu.

While it is not unexpected that there will be more variants of the coronavirus, prior to the detection of the B.1.1. 529, the Delta variant had been linked to high infection rate.

The Delta COVID variant was confirmed in Nigeria in July 2021, and is currently the most dominant strain in the country.
