The DRC's health ministry said it is believed that the hemorrhagic fever has killed 198 people in the northern Kivu and Ituri provinces, in which attacks from armed groups and community resistance to health officers have complicated response. The case, the second this year, began in North Kivu before spreading east to Ituri. Oly Ilunga Kalenga, DRC's health minister, said efforts to include the fatal causes have been hampered by violence against health and civilian officials as military groups fighting for control in the affected region.
The minister said that two health workers were killed in one attack. Last month, 11 civilians and a soldier were killed in the city of Beni – the middle of the case.
Mr Kalenga said: "There's no other epidemic in the world that has been as complicated as we are currently experiencing."
The US Agency for International Development (USAID) said there was concern that the case was in an active conflict zone in North Kivu, making it difficult for health workers to track and insulate cases.
A US official, on the condition of anonymity, told Reuters: "We are very concerned about the ongoing cases in the Democratic Republic of the Congo.

"It's happening in an area of active conflict, so physical uncertainty is a constant challenge and complexity of continuous response efforts.
"At present we do not see cases spread on any huge incredible geographical area."
The majority of cases were in the city of Beni and increasingly in Butembo nearby.
The rate of new cases has accelerated in recent weeks, and neighboring Uganda has said that it will start to vaccinate some of Ebola's health workers in case of viral hemorrhagic fever spreads from Congo.
The UDAID official said that current crisis "was not similar at this time to the cases that occurred in West Africa in 2014," which spread to nine countries and consisted of more than 28,000 cases.
The World Health Organization committee has stated that the case has not yet caused the public health crisis of international concern.
Congo has suffered 10 cases of Ebola since the virus was discovered near its river Ebola afonymous in 1976.

USAID said the US had used more than two dozen technical experts to the country to work with Congo's health ministry since the first cases were reported in August.
Since then, the United States has also used disaster and health specialists from USAID and U.S. Centers. for Disease Control and Prevention.
The official refused to provide specific details of responses and funding due to the security threat by armed groups.
He added lessons learned from the West African Ebola crisis in Congo, including better methods of treatment and isolation that allowed better patient care.
