BRUSSELS (AP) — Countries around the world slammed their doors shut again to try to keep the new omicron variant at bay Monday, even as more cases of the mutant coronavirus emerged and scientists raced to figure out just how dangerous it might be.
Japan announced it would bar entry of all foreign visitors, while new cases of the variant identified days ago by researchers in South Africa appeared in places such as Hong Kong and Australia. New cases in Portugal and Scotland might already point toward local spread of the variant outside of southern Africa.
“There might already be some community transmission of this variant in Scotland,” First Minister Nicola Sturgeon said after Scotland reported its first six cases.
The infections showed the near impossibility of keeping the genie in the bottle in a globalized world of travel and open borders.
Yet, many tried to do just that, even against the urging of the World Health Organization, 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 the protection of vaccines.
The WHO warned, however, that “the likelihood of potential further spread of omicron at the global level is high. Depending on these characteristics, there could be future surges of COVID-19.
