U.S. health officials said Tuesday that the more harmful Covid-19 variant known as delta has surged in the U.K., a country with high vaccination levels, in a warning to states as inoculation fades across the U.S.
Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases and an adviser to President Joe Biden, said at a news briefing that the delta variant that was first reported in India now accounts for more than 6% of cases being sequenced in the U.S. while in the U.K. it has overtaken the alpha variant that originated there.
