Coronavirus: Ómicron’s BA.2 sub-component is already prevalent in almost the entire world | What is known about this new mutation

The BA.2 sub-variable, also known as “Silent Omicron”, is advancing globally and has already become the dominant, According to the World Health Organization. This variant, more contagious than Omicron which has generated waves of record cases between December and January, is also prevalent in the United States, accounting for 54.9 percent of cases in the past week.

The Director of the European Department of the World Health Organization, Hans Kluge, considered that the infection began to increase again due to the proportions of BA.2, when it had already stabilized downward after the records of the northern winter. In early January, the United States recorded One million injuries in just 24 hours.

According to new data from the US Centers for Disease Control and Prevention (CDC), Omicron subvariant BA.2 is the new dominant mutation for covid-19. The US Northeast – with cities like New York – remains the hardest-hit region, with variant BA.2 causing more than 70 percent of all cases. The southern and western mountainous states are the areas with the fewest positives.

Until mid-March, the most common form on the planet was BA.1, but at the end of January its presence began to increase in the UK, India and Denmark. Then the experts noted that the BA.2 substrain differs from the first in some mutations, including the spiky protein, which the virus uses to enter the body.

The importance of analyzing this variant ability lies in the fact that it will determine its ability to escape from immune defenses and their virulence,
