Omicron Sub Variant Dubbed As Stealth Omicron Detected In 40+ Countries

A version of the omicron variant dubbed "stealth omicron" is being monitored by scientists and health experts around the world as it has been detected in more than 40 countries, but what is it and what does it mean for the pandemic? 

This version of the coronavirus, which scientists call BA.2, is widely considered stealthier than the original version of omicron because particular genetic traits make it somewhat harder to detect. Some scientists worry it could also be more contagious.

But they say there’s a lot they still don’t know about it, including whether it evades vaccines better or causes more severe disease.

BA.2 has lots of mutations. About 20 of them in the spike protein that studs the outside of the virus are shared with the original omicron. But it also has additional genetic changes not seen in the initial version.

It's unclear how significant those mutations are, especially in a population that has encountered the original omicron, said Dr. Jeremy Luban, a virologist at the University of Massachusetts Medical School.

The quick spread of BA.2 in some places raises concerns it could take off.

Since mid-November, more than three dozen countries have uploaded nearly 15,000 genetic sequences of BA.2 to GISAID, a global platform for sharing coronavirus data. As of Tuesday morning, 96 of those sequenced cases came from the U.S.

“Thus far, we haven’t seen it start to gain ground” in the U.S., said Dr. Wesley Long, a pathologist at Houston Methodist in Texas, which has identified three cases of BA.2.

The mutant appears much more common in Asia and Europe. In Denmark, it made up 45% of all COVID-19 cases in mid-January, up from 20% two weeks earlier, according to Statens Serum Institut, which falls under the Danish Ministry of Health.

If it's accounted for 45% of Denmark's cases and has been around since November, how the hell do they not know if it's worse or not? If hospitals in Denmark were filling up, we'd have an answer. Hate how they try to scare us with this stuff.

Data is obviously new still so its being studied. U never wanna jump to conclusions the moment u have some data available because there can be other factors that also affect things like hospitalization rates u cant link all of it to the variant alone

Each variant was more contagious than the last. At what point does it stop? :neyde:

For certainty, sure, but we knew very early on with Omicron that it was less severe because hospitalization didn't go up in South Africa when it spread there first. You don't have to say for certain, but you can absolutely let the public know what the latest data is pointing to. We all know things can change.

What im saying is even a piece of evidence shouldnt immediate be used to draw on conclusions

 

For example u bring up South Africa... Yeah hospitalizations didnt go up as quickly. But that didnt or doesnt prove Omicron was more mild

 

How much have vaccinations gone up since omicron vs last wave? How many natural infections too? Could it appear more mild simply because more ppl now have partial immunity? 

 

To figure that out it may require them to do deeper searching such as comparing vaccinated to unvaccinated or with previous covid infections and what the rate is.

 

Thats what i mean by analysing the details. Drawing conclusions from the obvious superficial data "hospitalizations didnt surge so obviously its mild" could be a potentially innacurate conclusion because ur going by the assumption that the results (number of hospitalizations) all stem from the one thing uve concluded (that its more mild)

 

And yes for Omicron there is a general consensus now that it is indeed more mild than delta since this new variant is a version of omicron that may be the case as well but again dont jump to conclusions too fast. Maybe omicron infections which came first gives u some protection against this so makes it appear mild who knows. Too early to say
