Over the course of the pandemic, genome sequencing of the virus and rapid sharing of data has been key to tracking the evolution of SARS-CoV-2 and early identification of emerging variants. SARS-CoV-2 sequencing data previously submitted from China to GISAID, a globally accessible repository of SARS-CoV-2 genome sequences, shows that over the months, the country has seen isolated cases linked to multiple variants of the virus seen previously. The World Health Organisation (WHO) has added another category of variants referred to as ‘Omicron subvariants under monitoring’.Currently, the Omicron subvariants being monitored under this category include BA.2.75, BA.4.6, XBB, BA.2.3.20 and sublineages of BA.5 including BF.7 and BQ.1. While the first sample belonging to lineage BA.4.6 dates back to December 2021, lineage BA.2.3.20 was detected in multiple countries recently in August 2022.
