Omicron reaches 57 countries, no clarity of its severity on health

Globally, the Omicron variant of the novel coronavirus has been found in 57 countries, but it is not yet clear, who dangerous it is to human health as compared to the Delta mutation, which is currently the dominating variant, the World Health Organisation (WHO) has stated, British news portal The Guardian reports.
The WHO has said in its latest Covid-19 report that the Delta variant continues to dominate cases, and more data is needed to determine Omicron’s infectiousness and severity. «While there seems to be evidence that the Omicron variant may have a growth advantage over other circulating variants, it is unknown whether this will translate into increased transmissibility,» the WHO report said.

There is too little data to know with certainty whether Omicron changes the severity of the illness. As of 6 December, all 212 confirmed Omicron cases across 18 European Union countries were classed as asymptomatic or mild, The Guardian reports.
