BUNIA (AP):Every time Vanny Birungi, a volunteer with the Red Cross in eastern Congo, goes out to raise awareness about the latest Ebola outbreak, as suspected cases near 1,000, she faces a double threat.One is the rare Bundibugyo type of Ebola, for which there is no vaccine or treatment. The other is the anger and suspicion of residents, who have pelted her with stones and subjected her to verbal abuse in Bunia, a city at the heart of the outbreak.

With cases spreading across provinces and borders, authorities are struggling with shortages, weak contact tracing, and the absence of an approved vaccine for the Bundibugyo strain

Health workers responding to a rapidly spreading outbreak of a rare type of Ebola in eastern Congo face two threats.
