Congo Ebola outbreak spreads to major city

The second-largest Ebola outbreak in history has spread to a major city in eastern Congo, as health experts worry whether the stock of an experimental vaccine will stand up to the demands.

Butembo, with more than one million residents, is now reporting cases of the deadly haemorrhagic fever. There were currently 471 Ebola cases, of which 423 are confirmed, including 225 confirmed deaths, Congo’s health ministry said.
