Anthony S. Fauci, the country’s top infectious disease expert, reiterated during Saturday’s White House briefing that while social distancing efforts are working across the country, the risk of a coronavirus resurgence is real. “That is our most important tool,” Fauci said of mitigation. “As sobering and as difficult as this is, what we are doing is making a difference.”

Meanwhile, confirmed cases of coronavirus in the United States surpassed 300,000, with more than 8,000 deaths. New York’s death toll topped 3,500 as confirmed cases rose to 113,704.

Here are some significant developments:
