Some 40 people are suspected of having contracted the disease, which is 90 percent lethal. They are all waiting for laboratory tests.
Health Minister Oly Ilunga relaunched on Friday the campaign to raise awareness of the response against Ebola in Beni, a city in the northeast of Congo with more than one million inhabitants.
The tenth outbreak of the disease was reported on Aug. 1 in Mangina, just 30 kilometres from Beni.
In addition to being an area dominated by irregular armed forces, entire neighbourhoods have refused to receive attention from health teams or preventive vaccination.
While in the rest of the affected territories, which includes the neighbouring province of Ituri, the number of contacts of the sick is more than 90 percent, in Beni it is only 78 percent.
The DRC has already suffered 10 epidemics since the disease was discovered in 1976, two of them this year (the previous one in May in the northwestern province of Ecuador), but this is the fourth deadliest and the first to occur in the territory affected by the armed conflict.
The most lethal occurred in 1976 in Yambuku, in the north of the country, with 318 patients and 280 deaths.
Highly infectious, the Ebola virus is transmitted by contact with fluids from infected people and animals. The host can be either alive or dead.
