Fauci urges vaccination against COVID-19 variant spreading to US from India

White House chief medical adviser Anthony Fauci said on Tuesday that more than 6 percent of the sequenced COVID-19 infections in the U.S. trace to the highly transmissible Delta variant that was first found in India. The Delta variant, known by the scientific name B1617.2, has spread from India to 60 countries, including the United Kingdom, where it has become the dominant strain making up more than 60 percent of cases.
Fauci warned the Delta variant is “essentially taking over” the U.K. as its transmissibility “appears to be greater” than the Alpha strain, also known as B.11.7, that had been the most prevalent in the country after it was first discovered.
