Omikron already in Poland. The first case of this variant in our country was diagnosed by Sanepid in Katowice. Omikron is a variant of the coronavirus first detected in November 2021 in Africa. The main attention was drawn to the high number of mutations on the surface of the pathogen and its high infectious potential. Other important issues in the context of the Omikron variant are the symptoms accompanying the infection and the effectiveness of the vaccines against the virus. What do we know about the Omikron variant?

The Omikron variant worried scientists because it has as many as 50 different mutations
It was first detected in southern Africa, on December 16 it was found in Poland
For now, little is known about whether it is more dangerous than the Delta variant
The first reports of doctors show that the infection with Omikron gives mild symptoms

Omikron Variant – Why Was It Concern?

The Omikron variant is a new variant of the SARS-CoV-11 coronavirus detected on November 2 in Botswana. The omicron is also referred to as variant B.1.1.529, and was originally also referred to as Nu strain.

The detection of this variant of the coronavirus alarmed the scientific world as a surprisingly high number of mutations were identified in the virus protein. Additionally, the nature of the changes in the Omikron variant showed some similarities to those observed in the Delta variant. There was therefore a need to verify the degree of infectivity of the Omikron strain and its potential resistance to vaccines.

What distinguishes the Omikron variant?

The distinguishing feature of the Omikron variant is a large number of mutations that may facilitate its spread, affect the course of the infection and increase its resistance to vaccines. Scientists recognized 50 mutations in the Omikron variant, including 32 in the spike protein, that is, the spike protein responsible for infecting the host cells. New mutations may affect the pathogen’s contagiousness, but further research is still required to determine the actual risk of this strain of coronavirus.

Variant Omikron – zaraźliwość

The Omikron mutation was found to be of concern especially because of the high transmissivity potential and an increase in mortality among those infected. The structure of this virus variant shows some similarities to the Delta variant, especially in the structure of the spike protein.

Omicron, thanks to numerous changes in the peak protein, may turn out to be a virus that easily reaches human cells. In this case, there is a risk of the epidemic spreading rapidly and the dynamics of infections increasing.

Omikron variant – symptoms

The first reports of symptoms accompanying infection with the Omikron variant concern the condition of young people. Symptoms such as severe fatigue, body aches, slight headaches and a scratchy throat were observed. These are atypical symptoms that differ from those associated with other variants of the coronavirus, including the Delta variant.

The course of the disease after infection with the Omikron variant of the coronavirus in the young is light, and the patients do not require hospitalization – this is indicated by the initial analyzes of the patients’ health. However, it is still unclear how the disease occurs in the elderly or those with comorbidities.

Variant of Omikron – vaccines

Changes in the spike protein of the Omikron variant may increase the virus resistance to vaccines. If further research confirms this, it will be necessary to develop an appropriately modified vaccine. Due to the fact that we use mRNA vaccines to fight the SARS-CoV-2 virus, such a process could take several weeks.

The first results of the studies indicate that vaccination does not provide sufficient protection against Omicron infection, but is still effective against hospitalization and severe course.
