The World Health Organization has warned that the Covid-19 pandemic is far from over, as France, Germany and Brazil posted new records of infections in the past 24 hours.

The highly transmissible Omicron strain has spread unabated around the world, pushing some governments to impose fresh measures while speeding up the rollout of vaccine booster shots.

"This pandemic is nowhere near over," WHO chief Tedros Adhanom Ghebreyesus told reporters Tuesday from the agency's headquarters in Geneva.

Europe is at the epicentre of alarming new outbreaks, with Germany's cases soaring past 100,000 and France reporting nearly half a million cases on Tuesday.

The UN health chief warned against dismissing Omicron as mild, as the dominant Covid strain continues to flare new outbreaks from Latin America to East Asia after it was first detected in southern Africa in November.

"Omicron may be less severe, on average, but the narrative that it is a mild disease is misleading," he said.
