Reuters
South Africa and the UK are probably the two countries globally that have methodically sequenced the largest number of SARS-CoV-2 viruses isolated from patients, writes 
Felicity Burt, Dominque Goedhals, and
Sabeehah Vawda.
As we optimistically embarked on a new year with hopes of seeing an end to the global pandemic, masks, and social restrictions, our news channels were consumed with stories about virus variants and vaccine rollouts.
