The species of Ebola virus causing an outbreak in Congo that has killed nearly 120 people is less common than other Ebola viruses, which is complicating the response because there are no specific treatments or vaccines.

About 246 suspected cases & 65 deaths have been reported mainly in Mongbwalu and Rwampara health zones in Ituri province, near the Ugandan border.

No vaccines exist for Ebola Bundibugyo, which has caused 80 suspected deaths in the Democratic Republic of the Congo and one in Uganda

Bundibugyo virus disease has caused two previous outbreaks of Ebola in 2007 and 2012
