President-elect Joe Biden was sworn into office Wednesday, ushering in a new administration and fresh coronavirus policies as the country faces nearly 3,000 virus deaths a day. Biden plans to sign 17 executive orders in the first few hours of his tenure, including orders that will launch a "100 Days Masking Challenge," will see the U.S. rejoin the World Health Organization, and will bolster key Covid-19 personnel. The Biden administration will face a tall order to slow infection rates and speed up the national vaccine rollout.

The U.S. is recording at least 199,700 new Covid-19 cases and at least 2,960 virus-related deaths each day, based on a seven-day average calculated by CNBC using Johns Hopkins University data.
