Origin of inbound transmission lineages of COVID-19 in the UK 2020
Between January and May 2020, it was estimated by the COVID-19 Genomics UK consortium that the coronavirus was brought into the United Kingdom on at least different occasions. These importations each started a chain of transmission as the virus spread throughout the UK. In approximately ** percent of cases, the start of the transmission line was attributable to inbound travel from Spain, followed by **** percent virus introductions from Italy. Fewer than *** percent of chains of transmission arrived directly from China, where the coronavirus originated.
The latest number of cases in the UK can be found here. For further information about the coronavirus pandemic, please visit our dedicated Facts and Figures page.
