WHO Updates Ebola Measures as Congo Outbreak Reaches 60 Health Zones
The World Health Organization has updated its emergency recommendations as a Bundibugyo virus outbreak expands inside the Democratic Republic of the Congo, highlighting a central contrast: the danger is severe where transmission is occurring, but WHO still assesses the regional and global risk as low.
WHO rates the risk as very high in the Democratic Republic of the Congo, high in countries sharing land borders with it and low for the rest of Africa and the global level. The low global assessment reflects the absence of sustained transmission outside the Democratic Republic of the Congo—not the absence of imported cases or the possibility of further spread.
What changed on August 24
WHO’s second International Health Regulations emergency-committee meeting took place on August 18. After reviewing the outbreak, the WHO director-general issued updated temporary recommendations on August 24 for three groups of countries: the Democratic Republic of the Congo, countries with land borders adjoining it and all other countries.
For the Democratic Republic of the Congo, the recommendations provide more detailed guidance on surveillance, case detection, laboratory testing, infection prevention, clinical care, community engagement and health-worker protection. They also add or strengthen measures involving schools, mass gatherings, domestic mobility, road checkpoints and surveillance on inland waterways.
WHO also calls for daily reporting of suspected, probable and confirmed cases, 21-day monitoring of contacts after their last known exposure, safe and dignified burials, expanded testing capacity, protection and support for health workers, and information-sharing with neighboring countries when contacts cross borders.
The framework formalizes preparedness and coordination under the International Health Regulations. It does not impose a blanket international travel or trade ban. WHO’s recommendations say that suspension of flights or waterways routes and denial of entry to travelers from countries with community transmission are not recommended at this stage.
How large is the outbreak?
WHO’s latest detailed rapid risk assessment, covering data through August 13, recorded 4,566 confirmed cases and 2,128 deaths across six provinces and 54 health zones, a 47% crude case-fatality ratio.
The affected provinces are Ituri, North Kivu, South Kivu, Haut-Uélé, Tshopo and Bas-Uélé. Ituri remains the epicenter and has strong connections to Uganda and South Sudan through population movement, trade, mining and displacement.
Those WHO figures are not the same reporting snapshot as the newest national update. An Associated Press report published August 28, citing Congolese government figures, said the outbreak had reached 60 health zones, with 5,794 confirmed cases and 2,786 deaths. The totals differ because they cover different dates and reporting systems; the newer figures should not be presented as a direct correction to WHO’s August 13 assessment.
Why borders remain central
People move across the region’s formal and informal borders for work, trade, school, health care, family visits and refuge. That movement increases the chance that an infected person could reach a neighboring country before symptoms are recognized or contacts are identified.
WHO has documented imported cases in Uganda and France. It also reported that two patients diagnosed in the Democratic Republic of the Congo were subsequently treated in Germany. Sustained transmission has not been established outside the Democratic Republic of the Congo.
Uganda remains a particular preparedness focus because of its proximity to Ituri and its links to the affected area through trade, displacement and routine travel. WHO says Uganda’s monitoring and surveillance activities remain important because reintroduction remains possible while transmission continues across the border.
For travelers, aid groups and organizations operating in or near affected areas, the practical effect is stronger screening, information-sharing, contact follow-up and readiness measures—not an automatic shutdown of international travel.
A response constrained by insecurity and limited tools
WHO says there is currently no approved Bundibugyo-specific vaccine or therapeutic. Response teams therefore depend heavily on early detection, supportive care, infection prevention, contact tracing, safe burials and community cooperation.
The Democratic Republic of the Congo has begun vaccinating health workers and other frontline workers with Ervebo, a vaccine developed for a different Ebola virus. Its use should not be confused with an approved vaccine specifically for Bundibugyo virus. WHO-backed clinical trials are evaluating potential treatments, but investigational therapies are not the same as licensed standard treatment.
Operational conditions make the public-health measures harder to deliver. WHO and Africa CDC have highlighted insecurity, attacks affecting health facilities, infections among health workers, displacement, mistrust and funding gaps. The Associated Press also reported that a health-worker strike and intense population movement were complicating the response. These pressures can delay diagnosis, interrupt contact monitoring and reduce access to care.
What to watch next
The next indicators are the number of newly affected health zones, infections among health workers, additional imported cases, any sustained transmission outside the Democratic Republic of the Congo and whether international funding and response capacity expand.
The immediate humanitarian danger remains concentrated inside the Democratic Republic of the Congo, especially in Ituri and other affected provinces, even as the wider global risk assessment remains low. For neighboring countries, the priority is readiness: detecting imported cases quickly, tracing contacts across borders and keeping health systems prepared without disrupting essential movement and care.
