The coronavirus mutation first identified in the United Kingdom last year is now the dominant strain circulating in the U. S., U. S. Centers for Disease Control and Prevention Director Rochelle Walensky said Wednesday, and it may be the driving force behind the upward tick in new infections over the past few weeks.16,275. That’s how many B.1.1.7 cases have been reported in the U. S., according to the CDC, though the true count is likely far higher than CDC sampling indicates. The B.1.1.7 strain was first detected in England late last year, leading to the variant being nicknamed “the U. K. variant,” though researchers are still unsure if that’s where the mutation developed. The strain is believed to be behind the surge in coronavirus cases that prompted Prime Minister Boris Johnson to order another lockdown in January. A study by British researchers last month found evidence the B.1.1.7 strain is up to 70% more infectious and twice as deadly as previous strains. The strain was first detected in the U. S. in late December in a man living in rural Colorado with no travel history, which indicated the virus was already spreading within the community. The B.1.1.7 mutation has been detected in more than 100 countries and every U. S. state.
