The Omicron BA.2 sub-variant forms nearly 100% of new Coronavirus infections in South Africa, Tulio de Oliveira, a professor of bio-informatics who runs a gene sequencing institution and advises the government to a pandemic, said.
“As expected, Omicron BA.2 took over in South Africa, approaching the 100% new genome,” De Oliveira, announced the discovery of the original Omicron variant on November 25, said on Twitter. “What does it mean ? “
While BA.2 seems to be more contagious than the original Omicron variant there is no indication that it causes a more severe disease. De Oliveira previously said that it could cause a surge in the second infection in the wave driven by Omicron.
However, while South Africa is the first country to experience the main omicron wave the number of tapered infections. On Wednesday the country reported 3,628 new cases, down from nearly 27,000 records on December 15. The original Omicron strain itself is significantly more contagious than the previous variant such as Delta, but it seems to cause lighter disease.
