The World Health Organization (WHO) has warned that the Omicron coronavirus variant poses a high risk of infection surges around the globe, writes BBC.

The variant could lead to severe consequences in some regions, the WHO said.

The head of the organisation, Dr Tedros Adhanom Ghebreyesus, renewed a call for a global push to get vaccines to poorer nations.

COVID-19 is “not done with us” yet he warned.

The variant was detected in South Africa earlier this month with initial evidence suggesting it has a higher re-infection risk. South Africa has been praised for its prompt reporting of the variant.

“Omicron has an unprecedented number of spike mutations, some of which are concerning for their potential impact on the trajectory of the pandemic”, - the WHO said.

Speaking on Monday, Dr Tedros said scientists around the world are working to discover if the new variant is associated with higher transmission, risk of reinfection and how it reacts to vaccines.

“Omicron’s very emergence is another reminder that although many of us think we are done with COVID-19, it is not done with us”, - he said.

He added that no deaths have been linked to the new variant yet.
