Congo Ebola Outbreak Accelerates Toward Historic Death Toll

The Democratic Republic of Congo’s 2026 Ebola outbreak is progressing toward becoming the deadliest recorded outbreak of the disease, according to World Health Organization Director-General Tedros Adhanom Ghebreyesus. At its current pace, the outbreak could surpass the 2014–2016 West Africa epidemic, which killed at least 11,000 people. Declared officially on 15 May, the current outbreak has reportedly produced at least 4,300 cases and more than 2,000 deaths, although health officials believe transmission began several months earlier, in February. Early cases may have been misdiagnosed as malaria or typhoid, allowing the virus to spread before the outbreak was recognized. WHO officials say they hope to bring transmission under control within three months, while emphasizing that this would not necessarily mean the outbreak had ended. Dr Mohamed Janabi, the WHO’s Africa director, said health authorities were struggling to keep pace with the virus and were reaching only about 30% of cases. Regional instability in eastern DR Congo has made access and disease-control efforts more difficult. The outbreak involves the rare Bundibugyo species of Ebola, which has caused only two previously known outbreaks, in 2007 and 2012. There is currently no approved vaccine or established therapeutic drug specifically targeting this species. However, the UK’s Medicines and Healthcare products Regulatory Agency has authorized the first human trials of a Bundibugyo vaccine developed by the University of Oxford using technology from the Oxford-AstraZeneca Covid vaccine. Three other vaccine candidates are also in development. Separately, the WHO is sponsoring a clinical trial in DR Congo to assess whether two existing antiviral treatments can improve survival. Ebola symptoms can appear two to 21 days after infection and may initially resemble flu or malaria. The disease can progress to vomiting, diarrhoea, organ failure and death, and spreads through contact with infected bodily fluids.

The Ebola outbreak in the Democratic Republic of Congo has surpassed 2,000 confirmed deaths, making it the fastest-spreading Ebola outbreak on record, according to the latest government data. As of Tuesday, authorities had recorded 4,381 confirmed cases and 2,011 deaths. The outbreak reached its first 1,000 deaths in roughly nine weeks, but the next 1,000 occurred in only about three weeks, indicating that transmission is accelerating faster than responders can contain it. The outbreak, declared on May 15, is now the second-largest Ebola outbreak in history, behind the 2014–2016 West Africa epidemic, which caused more than 28,000 cases and over 11,000 deaths. It has affected five Congolese provinces and spread into neighboring Uganda. The World Health Organization has classified it as a public health emergency of international concern. Response efforts have been hampered by rebel conflict, poor roads, remote and vulnerable communities, and work stoppages by health workers protesting unpaid wages. Aid organizations also report that many new infections are occurring outside the network of monitored contacts, making containment more difficult. A WHO official said responders are effectively “chasing the virus” because transmission is moving ahead of the response. The outbreak is particularly challenging because it is caused by the rare Bundibugyo virus, for which no vaccines or treatments have yet been approved. Clinical trials have begun in Ituri, the outbreak’s epicenter. The WHO believes the outbreak began in February, months before it was detected, with early cases misdiagnosed as malaria or typhoid and some initial testing aimed at a more common Ebola strain. The current outbreak is Congo’s 17th and largest Ebola outbreak since the virus was first identified there in 1976.

The World Health Organisation (WHO) has warned that an Ebola outbreak in eastern Democratic Republic of Congo (DRC) could become the deadliest in history if it continues at its current pace. WHO Director-General Tedros Adhanom Ghebreyesus said the outbreak is on track to surpass the 2014–2016 West African Ebola epidemic, which recorded at least 28,000 cases and more than 11,000 deaths. That earlier outbreak took approximately eight months to reach 1,000 deaths; the current outbreak has already killed more than 2,000 people among over 4,300 reported cases. The outbreak was officially declared on 15 May, although genetic sequencing indicates that it began months earlier, in February. It is spreading rapidly in Ituri and other affected provinces in eastern Congo, particularly in remote areas near South Sudan, Uganda and Rwanda. Conflict, poor infrastructure, under-equipped health centres and strikes by unpaid health workers are hampering surveillance and treatment. Misinformation and distrust of outsiders are also preventing some residents from seeking medical care. The outbreak is caused by the Bundibugyo species of Ebola virus, for which no approved vaccine or treatment currently exists. Two vaccines developed specifically for this virus are now being tested in humans, while clinical trials of two possible treatments began in Ituri in July. WHO also plans to assess whether an existing Ebola vaccine could offer protection. WHO officials expect the outbreak to peak within six months under a moderate scenario, but they warn that it could continue for nine to 12 months under a less favourable scenario. Researchers cited in a Nature Medicine study found that the virus likely passed from an infected animal to a human and is genetically distinct from strains involved in earlier Bundibugyo outbreaks in 2007 and 2012. The findings suggest this is a new spillover event rather than a continuation of previous outbreaks.

Congo’s Ebola outbreak has killed at least 2,011 people among 4,381 confirmed cases, making it the fastest-growing Ebola outbreak on record, according to newly published government data. The outbreak has spread through five eastern provinces, particularly Ituri, amid rebel conflict, poor roads, interrupted communications and work stoppages linked to payment disputes, all of which have hindered medical surveillance and treatment efforts. Although the outbreak was officially declared on May 15, health authorities say genetic sequencing indicates it began in February. The death toll reached 1,000 in approximately nine weeks but doubled in only about three more weeks, suggesting that the disease is spreading faster than health workers can identify and isolate patients. The outbreak’s case-fatality rate is 45.9 per cent, higher than the 39.6 per cent rate recorded during the 2014–2016 West African outbreak. The disease is caused by the relatively rare Bundibugyo virus, for which there are no approved vaccines or treatments. Clinical trials have begun in Ituri. Health experts say delayed reporting of symptoms, reliance on traditional treatment, misdiagnoses involving malaria and typhoid, and initial testing for the wrong Ebola strain have all slowed the response. The World Health Organization has warned that officials are struggling to keep pace with the virus. Insecurity, population displacement, trade, mining and restricted access have continued to facilitate movement across the region, despite limits on public gatherings and the closure of Ituri’s main airport. Experts say early case identification and treatment in secure facilities are essential, but difficult to achieve in the remote and conflict-affected area.
