Conflict between military groups and government forces has made it difficult for health workers to access some of the most serious areas.
On Friday, an armed group attempted to attack the UN peacekeepers in the city of Beni in the state of North Kivu – the epicenter of the case.
The peacekeepers were able to push the attackers back after a number of hours of conflicts but all field activities were banished on Saturday because of the violence. The Crisis Operations Center remained closed and teams had to wait at their hotel.
Earlier in the week, at least seven police forces were killed and another 10 were injured in a co-ordinated military assault on rebel forces, the UN Foundation Stabilization Mission in the Congo Democratic Republic said.
Mortal violence in the Kivu state of the Congo has blocked efforts to stop the Ebola virus, says Public Health Minister Oly Ilunga Kalenga.
Babies are among dead
The case began – the second year – in the state of North Kivu before spreading into the province of Ituri in the east of the country. This is the 10th time since 1976 that Ebola has hit Congo.
Of all the reported cases, 311 so far have been confirmed as Ebola and 47 are likely. Amongst the deaths, 166 have been confirmed to have caused Ebola and 47 are likely, according to the nation's health ministry.
Among those killed during pregnant pregnancies and breastfeeding, newborn babies and babies, reported the World Health Organization. More than 30 health workers have also been infected, according to WHO.
Fear of spreading
Congo shares borders with nine nations, and UN fears that the Ebola epidemic could spread to South Sudan as a result of the influence of Congolese refugees.
Kalenga, the health minister, posted a video on the Ministry of Health Facebook page early on Saturday calling for communities to be vigilant and reporting any signs of illness.
"Community surveillance is at the heart of the new response strategy against #Ebola. All residents, at its level, can protect their family and neighborhood against the virus by reporting any warning and suspicious cases to emergency teams. #Beni neighborhoods work alongside us in the response, "he said.
Ebola first appeared in 1976 in Sudan and Congo, and is named after a river in the last nation. It is one of the world's finest diseases and is transmitted by direct contact with blood or other physical fluids of infected people.
Ebola causes fever, severe headache and, in some cases, hemorrhaging. It is spread by direct contact with physical fluids or objects that are contaminated by someone who is ill with the disease. In some cases, the virus is spread by contact with someone who has died of the disease.
The virus gets into the body through a cut skin or mucus membrane in the eyes, nose or mouth. It can also spread through sexual intercourse.
