Ebola's Deadliest Outbreak Spreads Amid Conflict

The Democratic Republic of Congo is experiencing its most severe Ebola outbreak to date, characterized by an unprecedented rate of new infections. This epidemic is complicated by the involvement of the rare Bundibugyo species of Ebola, for which no vaccine was initially available, though human trials have commenced. The outbreak's epicenter is located in an area affected by ongoing conflict, further hindering control efforts.

While daily new infections show signs of declining, suggesting some control measures are effective, the World Health Organization has cautioned against premature declarations of the peak passing. The Bundibugyo species, first detected over a decade ago, has a lower fatality rate than more common strains, but has still claimed approximately 48% of those infected in the current outbreak.

Significant efforts are underway to combat the virus. These include the first human trials of a vaccine developed by the University of Oxford, based on similar technology to the Covid-19 vaccine. Additionally, the country is preparing to test the Ervebo vaccine against the Zaïre species and evaluating two antiviral therapies, MBP134 and remdesivir, for their efficacy against Bundibugyo.

The outbreak's origin is traced back to a nurse who developed symptoms on April 24, with the virus potentially spreading undetected for weeks. The funeral ceremony of the first victim is believed to have contributed to its rapid spread. The Ituri province is the primary epicenter, though cases have been confirmed in North Kivu, South Kivu, and as far as South-Ubangi, bordering the Central African Republic. Neighboring Uganda declared itself Ebola-free on July 28 after recording 20 cases.
