WHO Issues First-Ever Comprehensive Guidelines for Ebola and Marburg as DRC Outbreak Deepens

The World Health Organization has for the first time published a comprehensive set of clinical management guidelines covering all known variants of Ebola and Marburg viruses, a landmark development that health experts say will fundamentally reshape how frontline medical workers respond to these deadly hemorrhagic diseases.

The timing of the release could not be more pressing. A severe outbreak of the Bundibugyo strain is currently tearing through the Democratic Republic of Congo, with health authorities having confirmed 837 cases and recorded 196 deaths. The scale of the crisis has lent particular urgency to the publication of the new guidance, spotlighting the devastating human cost these diseases continue to exact.

The outbreak has already spilled over DRC's borders. Uganda has confirmed 19 cases of the disease, with two of those patients losing their lives. Ugandan authorities traced each infection back to individuals who had traveled from the Democratic Republic of Congo, a development that has alarmed public health officials across East Africa and underscored how swiftly such outbreaks can cross borders.

Compounding the difficulty of the response is the absence of any approved vaccine or treatment specifically targeting the Bundibugyo strain. WHO cautions that even under an accelerated timeline, a vaccine could take up to nine months to become available — making the structured, evidence-backed supportive care outlined in the new guidelines the most powerful tool available to clinicians right now.

Central to the new guidelines are 16 evidence-based recommendations designed with practical application in mind for healthcare workers in outbreak settings. The recommendations address prioritized laboratory monitoring aimed at detecting treatable complications early, rapid oral and intravenous rehydration protocols, early administration of intravenous fluids and medications to manage shock, appropriately targeted antibiotic treatment for secondary bacterial infections, and carefully structured follow-up and survivor care. Together, they offer a step-by-step clinical approach grounded in hard-won field experience.

WHO Director-General Dr Tedros Adhanom Ghebreyesus summed up the stakes plainly, stating: "The current Bundibugyo virus outbreak is a stark reminder of the need for diligent, holistic and person-focused medical care." He further stressed that optimised supportive care has the power to reduce complications and should serve as the foundation upon which all clinical interventions are built.

The guidelines reflect lessons accumulated from a series of recent filovirus outbreaks and are intended to give health facilities — including those across East Africa — a clearer, evidence-driven framework for both preparing for and responding to future Ebola and Marburg threats.
