What Do We Know In regards to the Omicron Variant So Far?

There’s a lot that we don’t learn about Omicron, together with whether or not it causes extra extreme sickness than different variants, says Leana Wen, MD, an emergency physician and public well being professor at George Washington College.

However what we do know is that it’s a variant with an unusually excessive variety of mutations, or modifications within the virus’s genetic materials.

Early proof additionally reveals that the Omicron variant might unfold simpler than different COVID-19 variants, she says.

“That’s very regarding as a result of Delta, which is the dominant variant right here within the U.S. and around the globe, is already extraordinarily contagious. So, if that is much more contagious, it may displace the Delta variant,” says Wen.

Is the Omicron Variant within the US?

As of proper now, no instances of the Omicron variant have been reported within the US.

Both means, you need to keep calm, says William Schaffner, MD, a professor of preventive medication and infectious illnesses at Vanderbilt College Medical Heart in Nashville.

“And we all know the vaccines work towards Delta.”

Will COVID-19 vaccines present sufficient safety towards the Omicron variant?

“We don’t know whether or not the massive variety of mutations renders the vaccines much less efficient towards this variant,” says Wen.

“Though many scientists imagine — particularly with a booster shot — that it’s not going to render the vaccines ineffective.”

What are frequent signs of the Omicron variant?

We don’t have that data but, says Wen.

With a lot nonetheless unknown, what can I do proper now to guard my household and I from the Omicron variant?

“That features adolescents and kids 5 to 11.”

That is additionally a good time to get your COVID-19 booster, in accordance with Schaffner.

Booster pictures elevate your antibody ranges, which presents you each longer safety and stronger immune response towards COVID-19 variants, he says.

“I can’t let you know precisely what it [a booster shot] will do towards Omicron, however there’s prone to be, on the very least, partial safety,” Schaffer says.

“And partial safety is all the time higher than no safety.”

What Ought to I Be Most Involved About With the Omicron Variant?

Virus unfold, severe sickness, and vaccine effectiveness work hand in hand. Subsequently, all three are regarding, Wen says.

“Let’s say that one thing is extra transmissible, nevertheless it doesn’t trigger extra extreme illness and the vaccines work very nicely towards it. That’s not significantly regarding,” says Wen.

“Or, if one thing shouldn’t be very contagious nevertheless it’s nonetheless extra extreme, it’s additionally not as regarding as a result of it’s not going to displace Delta.”

“So, it truly is a mixture of those components that would make this variant very worrisome.”
