With schoolchildren returning to classrooms soon, many of them too young to be vaccinated, the pandemic is revitalizing. The most recent seven-day average of daily new cases, 66,606 for the week that ended Friday, jumped by 64 percent compared to the week before, the Centers for Disease Control and Prevention reported, up from 40,597.
