That's what we were missing.

A new Omikron variant BA.2.75 has appeared - also in Germany.

A British virologist describes this discovery as "alarming".

LONDON – New variants of the coronavirus keep popping up around the world.

Viruses mutate, including the Sars-CoV-2 coronavirus.

However, with a new omicron variant called BA.2.75, the alarm bells are ringing for virologist Thomas Peacock.

The British researcher from Imperial College London was one of the first to point the finger at Omicron at the unusual number of spike mutations.

"Worth keeping a close eye on

BA.2.75

- many spike mutations, likely second generation variant, apparently rapid growth and wide geographic distribution..." tweeted top London virologist.

Corona: Is the new omicron subtype BA.2.75 dangerous?

In his opinion, the new Omikron variant is a “second-generation variant”.

Which, according to the now unified scientific consensus, could be caused by chronic infections.

It is therefore the second generation of the

Omicron variant BA.2

.

Some of you will remember:

Omicron subtype BA.2 became established very quickly last winter, first in Denmark, Great Britain and then at the end of February 2022, dominantly in Germany.

For the difference between BA.1 and BA.2, the Charité virologist Christian Drosten tried a car comparison: Both have almost the same width tires, but in the case of BA.2 the engine has "a few more horsepower". 

Omicron subtype BA.2.75 also detected in Germany

And now the new Omikron variant BA.2.75 is appearing.

The new subtype has a large number of different mutations, according to virologist Thomas Peacock.

BA.2.75 has been detected in India, Great Britain, Canada and also Germany.

The sequenced cases in the laboratories are over 50. Experts estimate the spread to be higher due to the large geographical spread.

The data are still too small to assess the situation concretely.

At the moment, most of us probably have the Omikron BA.5 on our radar.

The proportion of the Omicron sub-line in Germany is now 66 percent, according to the Robert Koch Institute (RKI) in the latest Corona status report (as of June 30, 2022).

"It has become the dominant variant," according to the RKI.  

The Variant of Concern (VOC) Omicron is currently the dominant SARS-CoV-2 variant in Germany, according to the Robert Koch Institute (RKI) in the most recent Corona situation report (as of June 30, 2022).

"Other variants, such as the VOC Delta and before that the VOC Alpha, have been almost completely displaced and are currently only very rarely detected."

Coronavirus Sars-CoV-2: Variants of Concern (VOC) according to the WHO (as of July 4, 2022)

According to the RKI, the definition as a VOC occurs when there are indications of increased transmissibility, a more severe course of the disease and/or an immune vasive effect.

Alpha (B.1.1.7)

Beta (B.1.351)

Gamma (P.1)

Delta (B.1.617.2)

Omicron (B.1.1.529)

Corona virus in Germany: Omikron records the sub-lines BA.1 to BA.5 from the RKI

  • Omicron BA.1

  • Omicron BA.2

  • Omicron BA.3

  • Omicron BA.4

  • Omicron BA.5

New omicron variant BA.2.75 detected in five countries

The new Omikron variant BA.2.75 is a second generation of the BA.2 variant that dominated in Germany in winter.

The omicron variant BA.2.75 has already been detected in five countries.

  • Great Britain

  • Germany

  • Canada

  • New Zealand

  • India

Is the Corona variant actually developing “alarmingly”?

There have already been variants of Corona that looked scary at first and then disappeared from the scene.

The delta variant prevailed over the beta variant.

The beta variant was able to completely escape the immune system.

It will be a few weeks before we know if BA.2.75 is actually more contagious and even more sophisticated at tricking the immune system than previous variants.
