A new study has suggested that the Coronavirus variant first detected in the UK late last year is spreading rapidly across the US, raising concerns over another resurgence in the hardest-hit country.

Analysing half a million Coronavirus tests and hundreds of genomes, researchers have predicted that within a month, the UK variant, known as B.1.1.7, could become predominant in the US, potentially bringing a surge of new cases and increased risk of death, reports Xinhua news agency.
