A Médecins Sans Frontières staff member working on the Ebola response in the Democratic Republic of Congo has contracted the Bundibugyo virus and is being evacuated to the Netherlands for treatment, humanitarian and health officials said on Thursday.
The infected aid worker was transported to the Netherlands on a special medical flight and admitted directly into a high-level isolation unit at the Leiden University Medical Center, situated about 40 kilometers southwest of Amsterdam. Dutch health officials confirmed the patient’s arrival late Thursday, noting that specialized teams are managing the case under strict protocols designed for dangerous infectious diseases.
Medical personnel at the facility operate within secure units featuring double-door airlocks and dedicated intensive care rooms.
All precautionary measures are being taken to prevent transmission,
the hospital stated in its public briefing.

Leiden University Medical Center Admits Evacuated Aid Worker
The evacuation was executed under close coordination between health authorities in the Democratic Republic of Congo and the Netherlands. Doctors Without Borders, also known by its French acronym MSF, emphasized that every movement adheres to rigorous safety standards.
Dutch health authorities confirmed through correspondence with parliament that the staff member is placed in strict isolation
inside the Leiden facility. Officials from the aid organization declined to release further details regarding the patient’s current condition, citing strict medical confidentiality and privacy concerns.
Congo Records Its Largest Ebola Epidemic
Government figures released earlier in the week showed confirmed infections surging past 8,000 for the first time, reaching 8,067 cases alongside 3,901 deaths. A broader tally compiled by the National Institute of Public Health placed confirmed infections even higher at 8,224, with 3,982 deaths recorded since the epidemic began.
The aid worker’s diagnosis unfolds against the backdrop of Congo’s largest Ebola epidemic on record. Driven by the Bundibugyo strain, the outbreak has surpassed previous historical thresholds.
Risk Exposure and Containment Challenges Across Affected Provinces
MSF maintains active response operations across Ituri, North Kivu, Tshopo, and Haut-Uélé provinces. While response teams deploy advanced personal protective equipment and comprehensive training regimens, humanitarian leaders acknowledge the inherent dangers faced by frontline personnel.
According to data from public health briefings, nearly 80 percent of new infections are discovered among individuals who were not previously listed on contact tracing logs. Public health coordinators estimate that responders reach roughly 23 percent of expected contacts for known cases, even as authorities monitor more than 30,000 identified individuals.
Approximately 254 medical personnel have contracted the virus, resulting in 50 deaths among frontline health workers since the outbreak started. Across the wider region, international monitoring agencies and health ministries have recorded 8,245 confirmed cases, 3,984 deaths, and 2,140 recoveries spanning multiple affected nations.
Ebola transmits between people through direct contact with infected bodily fluids such as blood, sweat, vomit, or saliva. Initial clinical symptoms generally mirror flu-like manifestations including fever, intense headaches, and muscle aches, before potentially advancing toward severe internal and external bleeding.
The current emergency has outpaced the country’s 2018–2020 epidemic, ranking second historically only to the 2014–2016 West African outbreak that infected more than 28,600 people and killed over 11,000 across Guinea, Liberia, and Sierra Leone.
