Omicron spreading at unprecedented rate: WHO

World Health Organisation has alarmed that the new coronavirus variant Omicron is spreading at an unprecedented rate.

Addressing a media briefing in Geneva, WHO chief Tedros Adhanom Ghebreyesus said it is wrong to consider Omicron as causing mild disease.

He said the new strain has been detected in at least 77 countries and it is likely to have reached other countries as well.
