UK variant of COVID-19 is now most common strain in United States - CDC

WASHINGTON - The highly contagious variant of COVID-19 first discovered in the United Kingdom has become the most common strain of the virus in the United States as cases continue to climb, a top U.S. health official said on Wednesday.

The strain, known as B.1.1.7, was identified in Britain last fall and has since been detected in 52 jurisdictions in the United States, U.S. Centers for Disease Control and Prevention Director Dr. Rochelle Walensky told reporters at a White House briefing. U.S. public health officials have urged Americans to get vaccinated as soon as possible in part to prevent new variants of the novel coronavirus from spreading.
