Ebola outbreak in DR Congo growing 'exponentially' as death toll passes 2,500

More than half of the 2,500-plus deaths from DR Congo's Ebola outbreak have occurred within the past 20 days alone, as the virus spreads faster than any recorded outbreak, according to the UN's senior Ebola coordinator. Julien Harneis is urging a rapid scale-up of resources to prevent the epidemic from crossing into neighbouring countries.
