Ebola Outbreak Declared Emergency by WHO
ABUJA, Nigeria — The World Health Organization announced on Sunday that the Ebola outbreak in Congo and Uganda is a public health emergency of international concern.
A new outbreak was first identified in Ituri province, Congo, on Friday. By the next day, health officials were tracking 336 suspected cases and 88 fatalities, with the vast majority in Congo, though there are two cases in Uganda.
This outbreak is attributed to the Bundibugyo virus, a rare version of Ebola that poses challenges as there are no approved treatments or vaccines available.
Despite more than 20 previous outbreaks in both countries, with 17 occurring in Congo since the disease was discovered there in 1976, this marks only the third instance of the Bundibugyo virus being reported.
Understanding the WHO’s Declaration
The WHO indicated that this outbreak does not qualify as a pandemic, like COVID-19, and is not suggesting that nations close their borders.
Instead, the declaration aims to galvanize international support and resources, although past global reactions to similar declarations have varied. For instance, when mpox outbreaks were declared emergencies in 2024, there were criticisms regarding the slow delivery of essential supplies to affected regions.
Origin of the Outbreak
According to the Africa Centres for Disease Control and Prevention, the initial cases emerged in the Mongwalu health zone, a bustling mining area in Ituri. As patients sought medical assistance, cases spread to the Rwampara and Bunia health zones.
Ituri, located in a remote part of eastern Congo, faces logistical hurdles due to poor infrastructure, sitting over 1,000 kilometers from Kinshasa, the capital.
Health authorities have expressed concern about the outbreak’s proximity to Uganda and South Sudan. The main city of Bunia is close to the Ugandan border, and issues such as intense population movement and armed conflicts in the region, which have displaced many, add to the risk.
There are also challenges in tracing contacts, as local officials scramble to identify those who might have been exposed.
A Rare Strain of Ebola
The Bundibugyo virus, accountable for this outbreak, is distinct from the more common Ebola Zaire strain that has been prevalent in previous outbreaks except for one instance.
The virus was first noted during an outbreak in Uganda’s Bundibugyo district between 2007 and 2008, claiming 37 lives. The second occurrence was in 2012 in Isiro, Congo, resulting in 57 cases and 29 deaths.
The WHO explains that Ebola is caused by a group of viruses, with three known to lead to significant outbreaks: Ebola virus, Sudan virus, and Bundibugyo virus. Dr. Gabriel Nsakala, a public health expert involved in earlier Ebola responses, mentioned that while Congo has substantial experience in containing such outbreaks, the unique strain could complicate matters.
Efforts to Address the Outbreak
Immediately after the outbreak’s confirmation, the Africa CDC organized a high-level meeting with health authorities from Congo, Uganda, South Sudan, and other key partners. Their discussions revolved around urgent response strategies, cross-border coordination, and resource mobilization.
Dr. Jean Kaseya, the Africa CDC Director-General, indicated that measures such as deploying resources and teams, isolating high-risk individuals, and enhancing surveillance are underway.
Logistical Difficulties in Congo
As Africa’s second-largest country by land area, Congo often encounters logistical challenges in managing health crises, especially given the poor condition of roads and long distances involved.
Last year, during a brief outbreak, the WHO faced significant delays in providing vaccines, highlighting the systemic issues within the response mechanism. Funding remains a pressing concern; the WHO reported releasing $500,000 for the current outbreak response, while the Africa CDC announced mobilizing $2 million, which still falls short of the necessary funds.
Past U.S. funding cuts have also raised concerns about the capacity to respond to these health emergencies.
Transmission of Ebola
The Ebola virus is highly infectious and can jump from wildlife to humans. From there, it spreads among people through contact with bodily fluids like vomit, blood, or semen, and contaminated materials such as clothing or bedding.
This disease, though rare, can be extremely severe and often fatal, with symptoms including fever, vomiting, diarrhea, muscle pain, and in severe cases, internal and external bleeding.
The virus was first identified near the Ebola River in Congo back in 1976, with initial outbreaks occurring in remote villages close to tropical rainforests.
