The Democratic Republic of the Congo (DRC) has recorded over 9,000 confirmed cases of Ebola since May. This figure, in a report released on Tuesday by the Ebola task force, indicates 9,066 confirmed cases and 4,381 deaths as of October 11, bringing the overall mortality rate to 48.3 percent. Additionally, 2,389 patients have recovered from the disease.
Ebola Outbreak in Various Regions
This Ebola outbreak has affected 65 health zones across seven provinces. The eastern Ituri province is recognized as the epicenter of the disease, accounting for 73.8 percent of all confirmed cases. North Kivu province also has the highest mortality rate at 57.1 percent during this crisis.
The DRC Minister of Health, Roger Kamba, announced earlier this month that this outbreak is increasingly becoming localized, with several affected health zones reporting no new cases for weeks. However, Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, warned on October 7 that while the epidemic is declining in some areas, it is still rising in others.
Vaccine Trials and Challenges
This outbreak is caused by the Bundibugyo strain of the Ebola virus, for which no vaccine or specific treatment has yet been approved, although clinical trials are underway. The Ervebo vaccine, which is approved for the Zaire strain of Ebola, is being administered to frontline health workers under research protocols and through compassionate use arrangements.
According to the latest report, as of October 11, 399 frontline workers in the Haut-Uele province have been vaccinated, but its effectiveness against the Bundibugyo virus has yet to be established. The Coalition for Epidemic Preparedness Innovations announced on Tuesday that final preparations for a phase 2/3 clinical trial to evaluate vaccine candidates against the Bundibugyo virus are underway.
This trial, expected to begin in the coming weeks after receiving ethical and regulatory approvals, will likely first assess the Ervebo vaccine and then evaluate vaccines specifically developed for this strain as they become available.
The Ebola outbreak, declared on May 15, has become the largest and deadliest Ebola outbreak in the history of the Democratic Republic of the Congo and is considered the second largest outbreak globally after the 2014-2016 epidemic in West Africa.
