Omicron poses "very high" global risk but data on severity limited: WHO

The Omicron coronavirus variant, reported in more than 60 countries, poses a "very high" global risk, with some evidence that it evades vaccine protection but clinical data on its severity remain limited, the World Health Organization says. Considerable uncertainties surround Omicron, first detected last month in South Africa and Hong Kong, whose mutations may lead to higher transmissibility and more cases of Covid-19 disease, the WHO said in a technical brief issued on Sunday.
