(AP) – 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 of an epidemic with no end in sight. Butembo, with more than 1 million residents, is now reporting cases of the deadly hemorrhagic fever. That complicates Ebola containment work already challenged by rebel attacks elsewhere that have made tracking the virus almost impossible in some isolated villages. “We are very

concerned by the epidemiological situation in the Butembo area,” said John Johnson, project coordinator with Medecins Sans Frontieres in the city. New cases are increasing quickly in the eastern suburbs and outlying, isolated districts, the medical charity said. The outbreak declared on Aug. 1 is now second only to the devastating West Africa outbreak that killed more than 11,300 people a few years ago. There are currently 471 Ebola cases, of which 423 are confirmed, including 225 confirmed deaths, Congo’s health ministry said late Thursday. READ MORE
