Health secretary Sajid Javid on Monday confirmed that community transmission of the new Omicron variant of coronavirus was occurring in England, as the number of cases climbed to 336 across the UK.
Javid told the House of Commons there remained many unknowns in relation to the variant first identified in South Africa, but said the government would leave nothing to “chance” and proceed with “proportionate” measures.
“We don’t yet have a complete picture of whether Omicron causes more severe disease or indeed how it interacts with vaccines,” he told MPs. “We can’t say for certain at this point whether Omicron has the potential to knock us off our road to recovery.”
