UN: Ebola cases could eventually reach 20,000

GENEVA (AP) - The Ebola outbreak in West Africa eventually could exceed 20,000 cases, more than six times as many as are known now, the World Health Organization said today as the United States announced plans to test an experimental Ebola vaccine. Currently, about half of the people infected with Ebola have died, so in a worst-case scenario the death toll could reach 10,000, the agency said, according to a plan released Thursday on how to stop the outbreak.
