The new coronavirus variant Omicron is spreading across the globe at an unprecedented rate, the World Health Organization, WHO, has warned. Cases of the heavily mutated variant have been confirmed in seventy-seven countries.
But at a press conference, WHO chief Tedros Adhanom Ghebreyesus said it was probably in many others that had yet to detect it. Tedros maintained that he was concerned that not enough was being done to tackle the variant. The global health agency latest data suggests the variant, first detected in South Africa in November, can better evade existing vaccines and carries a higher risk of re-infection, leading the organisation to say the level of risk remains very high.
