From the Summary: "The United Kingdom (UK) has faced a rapid increase in COVID-19 [coronavirus disease 2019] case rates in the South-East, the East and the London area, which is associated with the emergence of a new SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] variant, VOC [variant of concern] 202012/01. As of 26 December 2020, more than 3,000 cases of this new variant, confirmed by genome sequencing, have been reported from the UK. An increasing proportion of cases in the South East, the East and the London area are due to this variant, but cases have also been identified in other parts of the UK. Although it was first reported in early December, the initial cases were retrospectively identified as having emerged in late September. Preliminary analyses indicate that the new variant has increased transmissibility compared to previously circulating variants, but no increase in infection severity has so far been identified. Since 26 December, a few VOC 202012/01 cases have also been reported in other EU/EEA [European Economic Area] countries (Belgium, Denmark, Finland, France, Germany, Iceland, Ireland, Italy, the Netherlands, Norway, Portugal, Spain and Sweden) and globally (Australia, Canada, Hong Kong SAR, India, Israel, Japan, Jordan, Lebanon, South Korea, Switzerland, Singapore)."
