The survival rate can be increased by quarantine and swift treatment of symptoms.
The first cases of the latest outbreak were detected in April around the village of Kanungu, 300 kilometres (185 miles) from the provincial capital Kananga. Five cases of Ebola and one of Shigella had since been confirmed by international laboratories.
The medical charity Doctors Without Borders (MSF) has sent extra staff and equipment and has set up an isolation centre at Kampungu, where eight people have died out of 25 hospitalised since the start of September.
"At the moment we have seven people in isolation, including three in a serious condition. Three people died at the end of last week," MSF spokeswoman Pascale Zintzen told AFP.
The WHO is also sending a team to the area, as is US-based Centers for Disease Control and Prevention.
