Variant poses ‘very high’ risk: WHO

Early evidence suggests mutated coronavirus could lead to surges with ‘severe consequences’

The World Health Organization warned Monday that the global risk from the Omicron variant is “very high” based on early evidence, saying the mutated coronavirus could lead to surges with “severe consequences.”

The United Nations health agency, in a technical paper issued to member states, said “considerable uncertainties” remain about the variant that was first detected days ago in southern Africa. But it said it is possible the variant has mutations that could enable it to escape an immune-system response and boost its ability to spread from one person to another.

“Depending on these characteristics, there could be future surges of COVID-19, which could have severe consequences, depending on a number of factors, including where surges may take place,” it added.

“The overall global risk … is assessed as very high.”

The warning came as a widening circle of countries around the world reported cases of the variant and moved to slam their doors shut while scientists race to figure out just how dangerous this version might be. Japan announced it would bar entry of all foreign visitors, joining Israel in doing so just days after the variant was identified by researchers in South Africa. Morocco banned all incoming flights. Other countries, including the U.S. and European Union members, have moved to prohibit travelers arriving from southern Africa.

If the virus proves dangerous as feared, “the impact on vulnerable populations would be substantial, particularly in countries with low vaccination coverage,” WHO said, noting that no deaths linked to Omicron have been reported so far.

Spain became one of the latest countries to report its first confirmed case of the variant. While the vast majority of infections have been seen in travelers arriving from abroad, cases in Portugal and Scotland have raised fears that the variant may already be spreading locally.

“Many of us might think we are done with COVID-19. It’s not done with us,” warned Tedros Adhanom Ghebreyesus, WHO’s director-general.

Days after the variant sent a shudder through the financial world nearly two years into the pandemic that has killed over five million people, markets had mixed reactions Monday, with European stocks and oil prices rebounding and Wall Street opening higher, while Asian markets fell further.

U.S. President Joe Biden called the Omicron variant a cause for concern but “not a cause for panic.” He said he is not considering any widespread U.S. lockdown and instead urged vaccinations and maskwearing. The infections have underscored the difficulty in keeping the virus in check in a globalized world of jet travel and open borders. Yet, many countries are trying to do just that, against the urging of the WHO, which noted that border closings often have limited effect and can wreak havoc on lives and livelihoods. Some argued that such restrictions could provide valuable time to analyze the new variant. Little is known about it, including whether it is more contagious, more likely to cause serious illness or more able to evade vaccines.

While the initial global response to COVID-19 was criticized as slow and haphazard, the reaction to the new variant came quickly.

“This time the world showed it is learning,” said EU Commission President Ursula von der Leyen, singling out South African President Cyril Ramaphosa for praise.

‘‘ Many of us might think we are done with COVID-19. It’s not done with us.
