The spike in coronavirus cases in Florida, Arizona, Oregon and other Southern and Western states can be traced back to around Memorial Day, when officials began loosening their lockdowns, health experts said Monday. And in about two weeks, hospitals in those states could find themselves struggling to find enough beds for patients, one of the nation's top public health experts warned. In the last 14 days, Oregon has reported a 234.4 percentage jump in infections, Oklahoma jumped by 202 percent, Florida's number increased by 155 percent, and Arizona's confirmed coronavirus cases climbed by 142 percent, according to an NBC News analysis of state health department figures. Texas, Utah, Arkansas, Louisiana and more than a dozen other states — as well as Guam and the Virgin Islands — had increases in the numbers of reported cases in the last two weeks.
