Authorities in Liberia and Sierra Leone are struggling to figure out the number of new cases and where the virus is mainly concentrated, the head of the U.N. Mission for Ebola Emergency Response (UNMEER) said Tuesday. "The challenge is good information, because information helps tell us where the disease is, how it's spreading and where we need to target our resources," Anthony Banbury told The Associated Press in a telephone interview. Health officials said the first step to stop the outbreak from spreading is by isolating the cases but authorities in West Africa are having difficulty doing that because they do not know where the new cases are. "Unfortunately, we don't have good data from a lot of areas. We don't know exactly what is happening," Banbury said from UNMEER's headquarters in Ghana.
