As Omicron cases in the UK continue to surge, UK's health body has warned Omicron cases may account for 50 per cent of all COVID-19 infections in the UK by mid-December.

"If Omicron continues to grow at the present rate, Omicron case numbers are projected to reach parity with Delta cases in mid-December," the UK health security agency said.

UK Health Security Agency (UKHSA) said AstraZeneca and Pfizer-BioNTech provided much "lower levels of protection against symptomatic infection" compared to Delta. However, the report said "effectiveness against the new variant" appears to increase after a booster dose while emphasising that those over 40 should take the booster dose.

The UK health security agency said Omicron was detected in wastewater in the UK between November 26 and November 28. The report said the Omicron variant has a "transmission advantage" compared to Delta.
