Delta variant sub-lineage AY.12 found in India
The HinduSome cases of the Delta variant, the most widely prevalent variant of concern in India, are being “reclassified” to another sub-lineage that has been associated with a large number of cases in Israel, the India SARS-CoV-2 Genome consortium, which tracks emerging variants, said in a report on Monday. The Delta variant has birthed several sub-lineages called ‘Delta plus’ variants that bear most of its characteristic mutations but are different in other ways. Thus, it is not currently known whether AY.12 is clinically different from Delta,” the INSACOG report noted. However, its rapid growth in Israel means that it should be examined further.” The Delta variant, because of its preponderance in coronavirus cases globally, has several sub-lineages, making it necessary to reclassify them as not doing so would make naming them unwieldy, said Anurag Agrawal, Director, CSIR-Institute of Genomics and Integrative Biology.
