(CNN) Almost 2,000 cases of Ebola have been reported in the Democratic Republic of Congo, as the central African nation struggles with the second largest outbreak of the disease in history.

Health officials in the DRC said Sunday there were 1,994 reported cases of the disease, of which 1,900 have been confirmed as Ebola. So far, 1,245 people are confirmed to have died, with another 94 deaths reported.

The outbreak, which began last August, has proved difficult to bring under control because of community mistrust and violent attacks on health care workers.

Last month , the World Health Organization (WHO) said sporadic violence by armed militias, limited health care resources and difficult-to-access locations meant this outbreak was taking place in one of the "most challenging circumstances ever confronted by WHO."

WHO epidemiologist Dr. Richard Mouzoko was killed by armed men in April while working in Butembo, in North Kivu, a province grappling with a long-term conflict and dozens of armed groups.
