Variant of concern

The World Health Organization (WHO) has labelled Omicron as a variant of concern and has said the "overall global risk related to the new variant...is assessed as very high", but has warned governments against closing their borders now that the variant has been detected in many countries.

"Flight bans have been imposed on southern African countries, but so far only two have detected the new variant. Meanwhile countries in other regions have reported cases of Omicron," , WHO Regional Director for Africa, highlighted earlier this week.

The variant was identified only on November 24, and there are still many unknowns. While investigations continue, the WHO is recommending that nations take "a risk-based and scientific approach and put in place measures which can limit its possible spread" and to "" to maintain essential health services.

"We don't know very much about this yet," Maria Van Kerkhove, the World Health Organisations (WHO) technical lead on COVID-19, on the new variant last Thursday. "What we do know is that this variant has a large number of mutations, and the concern is that when you have so many mutations it can have an impact on how the virus behaves."

As research continues, the WHO has praised South Africa and Botswana for quickly sharing information about the new strain so that governments could intervene early to take extra precautions to monitor and attempt to curb the spread.

“The speed and transparency of the South African and Botswana governments in informing the world of the new variant is to be commended. WHO stands with African countries which had the courage to boldly share life-saving public health information, helping protect the world against the spread of COVID-19," said Dr Moeti.
