NEW YORK — The coronavirus crisis deepened in Arizona on Thursday, and the governor of Texas began to backtrack after making one of the most aggressive pushes in the nation to reopen, as the daily number of confirmed cases across the U.S. closed in on the peak reached during the dark days of late April.
While greatly expanded testing probably accounts for some of the increase, experts say other measures indicate the virus is making a comeback. Daily deaths, hospitalizations and the percentage of tests that are coming back positive also have been rising over the past few weeks in parts of the country, mostly in the South and West.
In Arizona, 23% of tests conducted over the past seven days have been positive, nearly triple the national average, and a record 415 patients were on ventilators. Mississippi saw its daily count of confirmed cases reach record highs twice this week.
