Researchers HAD predicted that 2021 would become the year of variants. It has. Currently, there are four variants of concern, as per the World Health Organization (WHO), of which the Delta variant, implicated in India’s second wave of infections, has been reported from 124 countries and is set to become the most dominant variant circulating in the world.

In the UK, it forms 99.3 per cent of the sequenced samples in the four weeks preceding July 23 (see 'Fast-spreading variant', p18), while in the US, it is 73.7 per cent of the sequenced samples in the same period, as per the Global Initiative on Sharing Avian Influenza Data (GISAID), an online repository of genomic data from flu viruses.
