An Aug. 3, 2014 email from Chan to senior WHO staffers said logistics experts were receiving only a couple hundred dollars a week to cover thousands of dollars in expenses for basics like protective rubber boots and disinfectant for the Ebola outbreak in the summer of 2014 _ a problem that had been festering for four months. She warned that WHO needed to respond efficiently if it was to retain its leadership in the fight against Ebola. (AP Photo/Keystone, Jean-Christophe Bott, File)
