DR Congo's Ebola outbreak has grown to 2,011 confirmed cases, including 754 deaths, making it the fastest-growing on record, according to government data released overnight.

Health workers at Bunia General Hospital, the region's largest medical center, went on strike Wednesday and are the latest group to have walked off their jobs at the epicenter over payment issues.

Health professionals and other frontline workers barricaded the entrance of the hospital, claiming they have not received any compensation despite working under difficult conditions.

The World Health Organization says more than 100 health care workers have been infected since the beginning of the outbreak.

The Central African nation has been battling the Ebola outbreak caused by the rare Bundibugyo virus since May 15. A total of 753 patients remain in isolation or in hospitals, while 366 have so far recovered, according to Congo’s Health Ministry data.
