New coronavirus cases have fallen 14 percent in the United States in the past week, based on a seven-day average, although average daily cases, at more than 695,000, are still not far from the U.S. peak of about 762,000. Covid-19 hospitalizations are also close to their peak, straining short-staffed hospitals, but they are also starting to fall. Covid-19 deaths, which often lag days to weeks behind outbreaks, are still increasing nationally.
