Omicron instances have been already detected in Belgium on Friday. The Czech Republic, Austria, Israel and the Netherlands have been all investigating suspected instances of the variant.

There may be nonetheless comparatively little recognized about Omicron. It has mutations that scientists worry might make it extra infectious and fewer inclined to vaccines — although neither of those results is but to be established. Most confirmed instances of the variant are contained to southern African international locations, however there are worries the virus might have unfold extra extensively earlier than scientists there found it.

“There’s been a window of in all probability about two weeks conservatively that this virus has been spreading,” Andrew Pekosz, an epidemiologist from Johns Hopkins Bloomberg College of Public Well being stated in an interview on Saturday. It’s possible the variant is already in New York, he stated.

“There definitely is an opportunity that it has already unfold globally, however we simply don’t know but,” Mr. Pekosz added.

European leaders, already battling a surge in Covid-19 instances that has made it as soon as once more the epicenter of the pandemic, tried to strike a steadiness between growing warning and avoiding panic. However the virus wouldn’t cooperate.

Sixty-one passengers of 500 on two flights from southern African international locations into the Netherlands on Saturday examined constructive for Covid-19 and are quarantining in Amsterdam. The Omicron variant is more likely to be present in a few of these 61 passengers who examined constructive, the Dutch authorities stated.

In a information convention on Saturday night, Prime Minister Boris Johnson stated that to curb the unfold of the variant, face masks can be required in shops and on public transportation, a rule the nation had led to July.

Britain may even require vacationers from overseas to get a PCR check inside 48 hours of their arrival and require contacts of those that check constructive with a suspected case of Omicron to self-isolate for 10 days, no matter vaccination standing.

The variant was additionally detected in Hong Kong, which prompted “probably the most stringent boarding and quarantine necessities” for vacationers coming from south African international locations. Japan additionally issued journey restrictions for passengers from Botswana, Eswatini, Lesotho, Namibia, South Africa or Zimbabwe.

“I believe definitely warning is warranted to limit journey and to observe this intently, however on the finish of the day, we actually want much more knowledge to judge this new variant,” Philip A. Chan, an infectious illness physician at Brown College who has helped lead the Covid-19 response for Rhode Island, stated.

What we do know, he stated, is that the Omicron variant appears to be overtaking the Delta variant in south African international locations. This implies two issues: that the Omicron variant is extra contagious than the Delta variant, and that it could overcome among the pure immunity and vaccine immunity.

“Neither a kind of issues are good, clearly. And I believe that these are the 2 causes which have consultants and scientists so involved” Dr. Chan stated. However he nonetheless “urges warning and endurance.”

“Let’s wait to see what the info reveals. Let’s take applicable precautions,” he stated.

Dr. Chan additionally cautioned that with no strong world vaccination effort, “we’re half-treating the pandemic” and leaving the world open to new and extra transmittable variants.
