Britain reported its highest daily total of new coronavirus infections in a month while cases of a variant of concern first found in India continue to climb, official statistics showed on Thursday.
The overall incidence of infections in Britain is still low, while the number of people in hospital with COVID-19 fell to its lowest level since September on Thursday.
But clusters of the B.1.617.2 variant, believed to be more transmissible than the dominant Kent variant, are growing quickly, and could derail Prime Minister Boris Johnson's plans to reopen England's economy by the summer.
British cases of the B.1.617.2 variant first found in India have risen to 3,424, up by 2,111 compared to comparable figures last week, Public Health England said.
