The WHO convened an unbiased team of specialists on Friday to evaluate the new variant based mostly on the quick enhance in COVID-19 infections in South Africa this 7 days. Known scientifically as B.1.1.529, the variant was named Omicron.

“Omicron has some regarding properties. This variant has a substantial selection of mutations, and some of these mutations have some stressing attributes,” Maria Van Kerkhove, the WHO’s complex lead on the coronavirus pandemic, reported in a movie assertion.
