Between July and November 2021, the Delta variant has accounted for for at least 99 percent of the COVID-19 variants analyzed in the United Kingdom. However, in the two-week period up to January 5, 2022, the Omicron variant accounted for around 96 percent of SARS-COV-2 variants detected in the UK. The Omicron variant had been designated by the World Health Organization as a variant of concern in November 2021 and is regarded as more infectious than previous variants.
