Why is Ebola spreading in Africa?

Suspected Ebola cases in eastern Congo have climbed past 900, with at least 119 deaths, as the World Health Organization warns that the outbreak poses a ‘very high’ risk in the country, though it sees a low risk of spreading globally. Arson attacks on Ebola treatment centers, anger over tightly controlled burials and mistrust of authorities are fueling community backlash, complicating efforts to fight a virus with no approved vaccine.
