U.S. Policy Shift on Ebola Evacuations Raises Alarm Among Infectious Disease Experts
Key Insights
The U.S. is reportedly planning to send Americans exposed to or infected with Ebola to third-country facilities rather than repatriating them to specialized U.S. treatment centers.
Infectious disease physicians, including Ebola survivors and former CDC leaders, have written an open letter to Congress demanding transparency and oversight of the proposed policy.
Experts argue the U.S. already has a network of specialized biocontainment units and that safe repatriation was proven effective during the 2014–2016 West Africa epidemic.
The United States is reportedly planning to send Americans exposed to or infected with Ebola to facilities in third countries such as Kenya or those in the European Union, rather than repatriating them to specialized high-consequence infectious disease treatment centers within the United States. The policy shift, first reported by Helen Branswell in STAT, has drawn sharp criticism from infectious disease experts who argue it undermines both responder safety and global outbreak control efforts.
Krutika Kuppalli, M.D., an infectious diseases physician and former World Health Organization medical officer who served as medical director of an Ebola treatment unit in Sierra Leone during the 2014–2016 West Africa epidemic, warned that the assumption that the United States would bring exposed or ill responders home "now appears to be changing."
"At first glance, such a policy may seem practical. Why bring Americans potentially exposed to or infected with Ebola back to the United States when facilities could be established elsewhere?" Kuppalli wrote. "The answer is straightforward: because we have already shown that safe repatriation works."
Proven Capabilities Already Exist
Following the 2014–2016 West Africa Ebola epidemic, the United States invested heavily in a network of specialized biocontainment units. These facilities include highly trained multidisciplinary teams, specialized transport systems, advanced laboratory capabilities, and years of operational experience managing patients with dangerous infectious diseases.
"Those capabilities were not built overnight and cannot be recreated overnight," Kuppalli emphasized. During the West Africa epidemic, multiple Americans exposed to and infected with Ebola were safely evacuated to the United States and treated in specialized centers. Most survived, and critically, those evacuations did not result in secondary community transmission.
The current outbreak, which began in late April, is centered in the Democratic Republic of the Congo's politically unstable northeastern Ituri Province and has spread to Uganda. As of June 6, the disease had sickened 534 people and claimed 93 lives, according to data cited by the University of Colorado Anschutz School of Medicine.
A Different and More Challenging Virus
Daniel Pastula, M.D., MHS, professor of Neurology, Infectious Diseases, and Epidemiology at the University of Colorado Anschutz School of Medicine and Colorado School of Public Health, noted that the Bundibugyo virus driving the current outbreak presents distinct challenges. Unlike the Zaire virus responsible for the West African epidemic—which has a mortality rate of 60% to 90% but can be treated with two monoclonal antibodies (search) and prevented with a vaccine—the Bundibugyo strain has a mortality rate of 30% to 50% and currently has no approved treatment or vaccine.
"Viruses do not respect borders," Pastula said. "The longer an outbreak continues and the bigger it gets, it's very possible that someone who had contact with someone with Ebola could travel here. For our own best interests, it is better for the outbreak to end soon."
Concerns Over Responder Willingness and Resource Allocation
Kuppalli argued that the proposed policy could deter experienced clinicians from deploying to outbreak zones. "Outbreak response is difficult enough without asking responders to wonder whether they will have access to the best available care if they become ill," she wrote. "If experienced clinicians begin to view deployment as carrying greater personal risk, some will understandably choose not to go."
She also raised concerns about resource stewardship, noting that funds spent establishing ad hoc facilities overseas are resources not directed toward controlling the outbreak at its source. "The United States already maintains a network of specialized biocontainment units built for exactly these situations. Creating parallel capabilities overseas risks duplicating existing infrastructure while diverting attention and resources from the interventions most likely to bring the outbreak under control."
International Partnership Strains
The proposal has generated public concern and political controversy in Kenya, which has long served as a regional hub for public health and humanitarian response. Reports indicate that protests over the proposed plans turned deadly in Kenya this week.
"Many Kenyans are asking a reasonable question: Why should their country be asked to host facilities intended primarily for citizens of another nation when the United States already possesses a well-established network of specialized treatment centers capable of safely caring for patients with Ebola?" Kuppalli noted.
Call for Congressional Oversight
A group of physicians—including former Centers for Disease Control and Prevention (search) Chief Medical Officer Debra Houry, former CDC Principal Deputy Director Anne Schuchat, emergency medicine physician and Ebola survivor Craig Spencer, and Kuppalli—with support from the Infectious Diseases Society of America (search), have written an open letter to Congress calling for transparency, accountability, and oversight of any plans to quarantine, isolate, or treat Americans in third-country facilities.
The letter highlights critical questions regarding standards of care, medical evacuation capabilities, responder recruitment and retention, patient rights, and the potential diversion of resources from controlling outbreaks at their source.
The Fundamentals of Containment
Pastula emphasized that the basics of biodefense—isolation of infected individuals, contact tracing, quarantine and monitoring of close contacts, medical facilities with appropriate personal protective equipment, coordination between health partners, and robust vaccine and treatment development pipelines—remain essential to controlling the outbreak.
"It's incumbent on all of us to have an appropriate response and collectively work to eradicate outbreaks such as this one in a coordinated fashion," Pastula said.
The Ituri Province presents particularly difficult conditions, with ethnic clashes, heavy migration, struggles over resources, and misinformation about Ebola all undermining containment efforts. "You combine all of these factors, and you have the recipe for a disaster," Pastula said. "No medical condition is solely an individual medical condition. All involve public health and population health at some level."
Kuppalli concluded: "Ultimately, this debate is about far more than where a handful of Americans might receive care. It is about what kind of outbreak response system we want to build and whether the United States will continue to lead in global health emergencies or retreat from commitments it has long embraced."
