Biden's 100 days in office: Is America back open? COVID outbreak check, status of schools, mask guidelines

President Biden is now 100 days into his term in office, a marker that leaders often point to when promising to hit the ground running and get things done for the American people. Here is what he has accomplished -- and what remains the same -- when it comes to the coronavirus pandemic.

On Jan. 20, the day of Biden's inauguration, there where 188,530 reported new COVID-19 cases, with a seven-day moving average of 194,061, according to the Centers for Disease Control and Prevention. The most recent day reported, April 27, had 50,061 new cases and a seven-day average of 53,934. The sharp decline began following a spike during the holiday season but also at a point when vaccines from Moderna, Pfizer and Johnson & Johnson became increasingly available to the general public. According to the CDC, more than 98 million people in the U.S. are fully vaccinated, with more than 142 million having received at least one dose of a vaccine, as of April 28.
