What is AY 4.2 Subvariant of Delta?
AY 4.2 Delta Variant is a most newest mutation of the SARS COV-2 virus. It is a sub lineage of Delta Variant of this coronavirus.
The University of Columbia carried out a deep dive research on the mutations of Coronavirus and based out of the research it has identified as many as 75 lineages of this virus. The most concerning variant is AY 4.2. It is one such sub lineage of Delta Variant which is rapidly spreading out in many countries specifically in UK. There has been a drastic spike in the cases of Delta variant cases in recent months.
