Florida leads the country with the highest number of cases of the B.1.1.7 strain, followed by Michigan and Minnesota, according to the CDC data. Emergency physician and CNN Medical Analyst Dr. Leana Wen says she's worried about what this could mean for Michigan and the US. "What's happening in Michigan now could very well happen in other states," she said on CNN Saturday. The encouraging news, Wen added, is that Covid-19 vaccinations are speeding up which could help blunt another potential violent surge in the country. Meanwhile, a recommended pause on the Johnson & Johnson Covid-19 vaccine continues in the US .
