whole-genome sequencing (WGS) provides the highest possible subtyping resolution improving the surveillance, outbreak investigation, source attribution, and microbial population studies

BA.2 sub-lineage has even higher propensity to spread among people and has the ability to infect people who have been fully vaccinated and/or previously infected by escaping from neutralising antibodies induced by vaccination or infection.

Genome sequencing is complex, and only 38 laboratories across the country (https://bit.ly/3ED4vrP) have the ability to sequence a virus which is as infectious as this
