The confirmed cases of Ebola in the Democratic Republic of the Congo have reached 2011, including 754 deaths, according to government data for what authorities say is the fastest-growing outbreak on record.
A total of 753 people remain in isolation or in hospitals, while 366 have recovered, according to data from Congo's health ministry on Wednesday.
Contact tracing remains a challenge, with coverage of those exposed still at 67 per cent.
The Central African nation has been battling the Ebola outbreak caused by the rare Bundibugyo virus since May 15.
Two months since the onset, the outbreak continues to spread faster than health officials can track despite an expanding response.
At least 80 per cent of new cases were emerging from unknown chains of transmission, the World Health Organisation said on Tuesday.
