Virologists suspect that it is able to evade the immune response even more effectively than BA.5.

WHO is studying the spread of a new sub-variant of the omicron strain, which has already been found in many countries and may soon become dominant in the world, according to fortune.com.

Sub-variant BA.2.75 was named Centaurus. So far, it is inferior in activity to sub-variant BA.5, but WHO is already tracking a new variety of omicron. BA.2.75 was first recorded in early June in India in early June. It has since appeared in the US, Australia, Canada, Germany, New Zealand and the UK. Along with the usual mutations characteristic of the omicron, nine more have been identified in it, which, given the rapid spread across the planet, is of concern to virologists.

The contagiousness of the new variant, its ability to avoid an immune response, and the severity of the disease caused are not yet known. However, some experts believe that its inherent mutations can more effectively break through the immune defense compared to BA.5 and BA.4 - despite the fact that the latter successfully evade immunity obtained as a result of both vaccination and previous infection.
