Abstract

The highly transmissible variation of COVID-19 has a new sub-variant known as a variant BA.2.75, which was initially discovered in India and is now found in at least 10 more countries. The World Health Organization (WHO) officials said that the new variant is actively being monitored. It has yet to be determined if the new variation is more clinically severe than its predecessors. It is known that the Omicron strain sub-variants are responsible for this rise in the worldwide COVID tally. It is too early to know if this sub-variant exhibits additional immune evasion characteristics, or is more clinically severe.

The extremely contagious BA.2.75 sub-variant of Omicron has been documented in India, but there is no evidence yet that it has increased disease severity or dissemination. Many of the BA.2 lineage's sublineages form a unique collection of mutations as it evolves. A related branch of the BA.2 lineage is B.2.75. The size of genomic sequencing must be increased and maintained for the early detection of the variant strains of SARS-CoV-2. BA.2.75 is the second generation of BA.2 variations and has a high transmissibility level.

Keywords: COVID-19, BA.2.75 variant, transmissibility, WHO, second-generation of BA.2 variations, mutations.
