South Africa is keeping a close watch on a newly detected COVID-19 variant, known as Nimbus or NB.1.8.1, which is contributing to a spike in infections across parts of Asia. The World Health Organization (WHO) has classified the variant as one “under monitoring” due to its growing prevalence in several countries.
Health Minister Dr Aaron Motsoaledi provided an update during the 4th Health Working Group meeting of the G20, currently taking place in Johannesburg. He confirmed that the National Institute for Communicable Diseases (NICD) is actively tracking the spread of the variant as part of South Africa’s comprehensive disease surveillance efforts.
“We have robust systems in place, and our sentinel surveillance programme continues to test for key respiratory viruses including SARS-CoV-2, influenza, and RSV,” said Motsoaledi. “At present, our data indicates very low levels of COVID-19 activity in South Africa.”
The new variant, a descendant of the Omicron lineage, has recently led to an increase in cases in India and has been detected in other countries such as Thailand, Indonesia, China, and the UK. According to reports, the UK Health Security Agency confirmed 13 cases of NB.1.8.1 in England last week.
Despite the emergence of this new strain, the Minister reassured the public that updated vaccines remain effective against it, and there is currently no need for additional public health restrictions.
“We are also seeing a seasonal rise in flu cases, but the country is well-prepared to manage the situation,” he added. “Basic hygiene practices such as frequent handwashing, covering coughs, and staying home when sick remain vital in preventing the spread of respiratory illnesses.”
Motsoaledi also encouraged global cooperation to address current and future health challenges. “We must work together with urgency and unity to strengthen global health systems built on solidarity, equity, and cooperation.”
The G20 Health Working Group meeting, running until Friday, brings together global health leaders, policymakers, and experts from leading economies, international organisations, and invited nations. Discussions are focused on strengthening access to health tools in low- and middle-income countries, expanding regional manufacturing capacity, supporting technology transfer, and promoting regulatory harmonisation and sustainable financing for future health emergencies.
