Officials in states with surging coronavirus cases issued dire warnings and blamed outbreaks on early reopenings Sunday as the seven-day average for daily new cases in the United States reached a record high for the 27th straight day.

“We don’t have room to experiment, we don’t have room for incrementalism when we’re seeing these kinds of numbers,” said Judge Lina Hidalgo (D), the top elected official in Harris County, Tex., which encompasses the sprawling Houston metro area. “Nor should we wait for all the hospital beds to fill and all these people to die before we take drastic action.”
