A “variant of concern” typically has characteristics like increased transmissibility, disease severity or immune escape – meaning that immunity granted through vaccination or previous infection with COVID-19 is likely to be less strong against this variant, the WHO said.

With the designation of the Omicron variant as a variant of concern, the WHO is asking countries to enhance surveillance activities, report findings to the WHO, and report initial cases and clusters of infection.

A number of countries have already announced travel restrictions to South Africa and other nations that have reported cases of this COVID-19 variant.

This is a developing story. More information to come.
