Recent data from Africa’s Centres for Disease Control and Prevention show that confirmed Ebola cases linked to the Bundibugyo virus strain have risen by 38 percent in one week, with totals surging to 894 confirmed cases with 204 deaths reported across affected areas in the Democratic Republic of the Congo and Uganda.
The increase brings the total to 32 health zones in eastern Congo. More than 90 percent of cases remain concentrated in Ituri province, with additional cases recorded in North Kivu and South Kivu provinces.
An additional 19 confirmed cases, including two deaths, have been identified in Uganda.
As of the most recent figures available from the U.S. Centers for Disease Control and Prevention, confirmed cases stand at 915 with 234 confirmed deaths when combining data from both countries. These case numbers are subject to change as investigations continue, while many experts believe the actual case total, and death toll, is likely much higher due to numerous issues with tracking in affected regions.
Earlier reporting from the Africa CDC placed the death toll above 200 at 204 with 894 cases at the time of the weekly update. A total of 74 patients have recovered from the illness across the affected regions in eastern Congo and Uganda.
The ongoing outbreak has been caused by the Bundibugyo virus, a less common strain of Ebola disease for which there are no approved vaccines or specific treatments. Supportive care remains the primary approach, while experimental options such as monoclonal antibodies are under development, officials have said.
Authorities confirmed the current outbreak on May 15, several weeks after health investigators first suspected its presence. The World Health Organization declared the situation a public health emergency of international concern on May 17
“For those 800 confirmed cases, we should have between 17,000 to 35,000 contacts that should be in our contact list,” Africa CDC epidemiologist Dr. Wessam Mankoula said in reference to ongoing contact tracing efforts. Mankoula further stated that only around 4,000 contacts had been tracked and evaluated at the time, representing less than 15 percent coverage.
“We are still far from controlling the situation of this outbreak,” he added.
Additional challenges include the remoteness of affected areas, as well as ongoing conflict in Ituri province, which has displaced upwards of one-million people. These factors complicate efforts to reach remote villages, which can require days of travel over poor roads and through dense forests.Mobile populations, including thousands of miners moving between sites in the mineral-rich region, add further difficulty to tracking potential exposures, officials have noted.
The current outbreak is described as three times larger than a prior Bundibugyo outbreak in Uganda in 2000 at a comparable stage, when that event had recorded 281 cases.
Mitigation efforts center on enhanced surveillance, isolation of confirmed and suspected cases, safe and dignified burials, and community engagement to encourage early reporting and adherence to public health measures. International partners, including the World Health Organization and the U.S. CDC, are providing support for these activities alongside Africa CDC.
