What happened

The virus causing a massive outbreak of Ebola in the Democratic Republic of the Congo could be mutating, health officials fear, as confirmed cases pass 4,000.

Why it matters

Africa’s public health watchdog said the time for incremental action was over as they announced plans to scale up every aspect of the response and go “door to door” looking for patients.

Common ground

The Ebola outbreak, caused by the Bundibugyo strain of the virus, was first reported on 15 May, although there are suspicions the disease could have been spreading since January.
