TIM COCKS ON Friday, November 19, Raquel Viana, Head of Science at one of South Africa's biggest private testing labs, sequenced the genes on eight coronavirus samples - and got the shock of her life. The samples, tested in the Lancet laboratory, all bore a large number of mutations, especially on the spike protein that the virus uses to enter human cells.

The pace of the work highlights the pressure on governments and public health authorities to decide quickly whether they need to take unpopular, economically damaging steps to curb Omicron's spread. Data shows it was circulating before it was officially identified in southern Africa last week and it has since been detected in more than a dozen countries. Work…
