The new COVID-19 variant Omicron is causing a rise in reinfections in South Africa, a scientist studying the strain has said, though also appears to have less severe symptoms. David Doyle has more.

Omicron is causing an increase in COVID-19 reinfections in South Africa, a scientist studying the new strain has said, and is fast overtaking Delta to become the country’s dominant variant.

Professor Anne von Gottberg, a microbiologist at South Africa’s National Institute for Communicable Diseases, was speaking at a World Health Organization press conference on Thursday (December 2).

“Previous infection used to protect against Delta but now with Omicron that doesn’t seem to be the case.”

However, she said she and her colleagues believe new infections and reinfections with Omicron would feature less severe symptoms.

COVID-19 cases are rising dramatically in South Africa – one of the southern African countries that first detected the variant.

Speaking at the same event, the WHO’s regional emergency director for Africa, Dr Salam Gueye, said the organization was working closely with countries to step up the response to the new variant.

“In South Africa, where WHO has already a team working in genomic sequencing, we are deploying a surge team in Gauteng province to support surveillance and contact tracing.”

But Gueye also warned that only 7.5% of Africans have been fully vaccinated against COVID-19 – and that 80% haven’t had a single shot.

“This is a dangerously wide gap.”

Many countries have imposed travel bans on passengers from southern Africa.

African leaders have protested – saying they are being punished for their transparency in reporting data on Omicron.

On Thursday Ghana said it had detected the new strain in 34 samples from travelers who returned to the country between November 21 and 25 – but gave no further details about those who were tested.

AI sector drives economic growth; Meta adjusts strategy, Palantir’s valuation sparks questions, and Nvidia leads amid rising competition.

The artificial intelligence sector continues to be a major driver of growth for both the U.S. and global economies. Companies at the forefront of AI innovation are influencing market trends and reshaping industries worldwide.

Meta’s stock has rebounded slightly following reports of potential cost-cutting measures and job reductions in its Reality Labs division. Investors are watching closely as the company adjusts its strategy to manage rising expenses and optimize innovation.

Palantir is trading at over 120 times forward sales and 180 times forward earnings, signaling investor confidence but also raising questions about valuation risks. Meanwhile, Nvidia maintains a market cap of $4.2 trillion as a leading AI chip supplier, yet competition is ramping up.

These moves highlight the growing tension between tech giants’ AI ambitions and the practical need to balance profits with heavy R&D spending.

Some analysts, however, warn that rapid growth may not be sustainable, with current levels of AI-related spending potentially overshooting realistic returns.

Analysts forecast $500 billion AI investment by 2026, transforming corporate spending priorities and enhancing economic productivity.

Analysts predict that artificial intelligence companies could invest over $500 billion in 2026, signaling a major shift in corporate spending priorities. This surge in capital allocation comes as businesses look to harness AI to drive growth and efficiency across multiple sectors.

Following strong third-quarter earnings, overall capital spending estimates for 2026 have been revised upward. However, investors are becoming more selective, focusing on companies that can clearly demonstrate revenue benefits from their AI investments, separating hype from tangible results.

AI adoption is expected to boost economic productivity, with significant investment already flowing into AI infrastructure such as semiconductors and data centres. The coming year could redefine how companies leverage technology to gain a competitive edge.
