WHO's Tedros concerned about 'tsunami of cases' from COVID-19 variants

The simultaneous circulation of the Delta and Omicron variants of the coronavirus is creating a 'tsunami of cases', World Health Organization (WHO) director-general Tedros Adhanom Ghebreyesus told a news briefing on Wednesday. 'Delta and Omicrom are now twin threats driving up cases to record numbers, leading to spikes in hospitalisation and deaths,' said Tedros. 'I am highly concerned that Omicron, being highly transmissible and spreading at the same time as Delta, is leading to a tsunami of cases.'
