In fight against virus, Biden looks for path back to normal

President Joe Biden spent his first 100 days in office encouraging Americans to mask up and stay home to slow the spread of the coronavirus. His task for the next 100 days will be to lay out the path back to normal. When he entered office, Biden moved swiftly to overcome problems with vaccine supply and more than tripled the country’s ability to administer them. But ending the coronavirus pandemic, the central challenge of his presidency, will require not only putting shots into arms — a task now growing more difficult as demand sags — but also a robust plan to help the nation emerge from a year of isolation, disruption and confusion.
