UK variant of COVID-19 now most common strain in U.S.

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.

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.

The United States has also detected cases of a variant first discovered in South Africa that is thought to be resistant to some COVID-19 vaccines and treatments. That strain has been found in 36 U.S. jurisdictions, according to federal data last updated on Tuesday, Reuters reported.

The United States is administering about 3 million COVID-19 vaccine doses per day on average over the past week, up 8% over the previous seven-day average, Walensky said. Vaccine supply has increased significantly in the United States in recent weeks as Johnson & Johnson has begun making millions of doses of its recently authorized shots. Pfizer/BioNTech and Moderna have also recently boosted their vaccine production capacity.

Still, daily U.S. cases of novel coronavirus are averaging 63,000 over the past seven days, up 2.3% from the previous seven-day average, she said.

According to Walensky, the CDC has identified a number of COVID-19 outbreaks tied to youth sporting events and that communities experiencing high case counts should avoid holding such events. Testing should also happen twice a week, she said.
