Absent "strong public health measures," widespread lockdowns will offer only a temporary defense against the spread of the coronavirus, a World Health Organization official said today. Authorities need to track the infected, "isolate them, find their contacts and isolate them," Mike Ryan, who heads the agency's Health Emergencies Program, told the BBC. Without those measures, "the disease will jump back up" once lockdowns are lifted.
How bad has it gotten? Globally, reports today surpassed 300,000 cases -- 21,000 in the U.S. -- and 13,000 deaths, as American manufacturers are pledging to ease shortages of respirators, masks and hand sanitizer.
