Delta variant drives Africa COVID threat to new level, WHO warns

The World Health Organisation () says with cases now doubling in Africa every three weeks, the Delta variant of COVID-19 has spread to 16 countries and it is present in three of the five nations reporting the highest caseloads.

The variant is the most contagious yet – up to 60 per cent more transmissible than other variants.

Along with Alpha and Beta, Delta is fuelling an aggressive third wave across Africa, with case numbers climbing faster than all earlier peaks, according to .

experts, on Thursday warned that the numbers had increased for six consecutive weeks, up by 25 per cent last week reaching 202,000 positive cases.

According to the health agency, deaths also rose by 15 per cent across 38 African countries, to nearly 3,000.

The Delta variant, initially identified in , is now dominant in South Africa, which accounted for more than half of Africa´s cases last week.

Moreover, the variant was detected in 97 per cent of the samples sequenced in Uganda and 79 per cent of those sequenced in the Democratic Republic of the Congo.

The variant also seems to be fuelling illness among young adults. According to WHO experts, in Uganda for example, 66 per cent of severe illness in people younger than 45, is attributed to Delta.

“The speed and scale of Africa’s third wave is like nothing we’ve seen before. The rampant spread of more contagious variants pushes the threat to Africa up to a whole new level.

“More transmission means more serious illness and more deaths, so everyone must act now and boost prevention measures to stop an emergency becoming a tragedy,” said Dr Matshidiso Moeti, WHO´s Regional Director for Africa.

The Alpha and Beta variants have been also reported in 32 and 27 countries respectively. Alpha has been detected in most countries in north, west and central Africa, while Beta is more widespread in the south.

Both are considerably more transmissible than the original virus.

With rising case numbers and hospitalisations across the continent, WHO estimates that oxygen demand in Africa is now 50 per cent greater than for the first wave peak, one year ago.

Eight vaccines have been approved for the WHO emergency use listing, however, shipments to Africa have, in effect, dried up.

“While supply challenges grind on, dose sharing can help plug the gap. We are grateful for the pledges made by our international partners, but we need urgent action on allocations.

“Africa must not be left languishing in the throes of its worst wave yet

“Only 15 million people – a mere 1.2 per cent of the African population – are fully vaccinated,” Moeti said. (NAN)
