The World Health Organisation has declared an outbreak of the Ebola virus in the Democratic Republic of Congo a public health emergency of international concern. Officials say there are now over 600 suspected cases, and over 139 suspected deaths.

This latest outbreak presents a series of difficulties for health officials. The outbreak is driven by a new strain of the virus called Bundibugyo, for which there is no vaccine. The epicentre of the outbreak is in the remote eastern province of Ituri, which is an active conflict zone. And local superstitions and beliefs frequently lead people to seek help at places of worship rather than from medical professionals.

We cover what you need to know about this current outbreak and how cases are being managed. Among others, we hear from BBC health correspondent James Gallagher and BBC presenter Anne Soy, who covered the 2014-16 Ebola outbreak in West Africa and later in the DRC.
