2026 Ebola Outbreak in DRC and Uganda: GeoVax CEO Warns of Growing Global Preparedness and Vaccine Response Gaps

As the 2026 Ebola outbreak expands across the Democratic Republic of Congo and Uganda, global health leaders are warning that the conditions surrounding this event could make containment more difficult than in previous outbreaks. In this Q&A with GeoVax CEO David Dodd, Infection Control Today^® (ICT^®) explores the operational, logistical, and preparedness challenges posed by the Bundibugyo strain, including fragile healthcare infrastructure, cross-border migration, barriers to vaccine deployment, and declining global investment in infectious disease preparedness.

ICT: The current Ebola outbreak in the Democratic Republic of Congo appears to be spreading faster than initially expected, with cases now raising international concern. From your perspective, what specific warning signs suggest this outbreak could become more difficult to contain than previous Ebola events, and do you believe global health agencies are underestimating the current level of risk?

David Dodd: The current Ebola outbreak raises concern not simply because of the number of cases, but because of the environment in which transmission is occurring. Several warning signs suggest this outbreak could become more difficult to contain than prior Ebola events.

First, we are seeing transmission pressures occurring in regions with fragile health care infrastructure and limited surge capacity. When health care systems are already strained, delays in diagnosis, isolation, and supportive care become more likely, increasing the opportunity for further spread.

Second, population mobility is a major concern. Cross-border migration, displacement, informal travel routes, and urbanization create conditions where cases can move faster than traditional containment systems can respond. Ebola historically was often easier to contain when outbreaks were geographically isolated. That assumption is becoming less reliable.

Third, global fatigue around infectious disease preparedness is real. After COVID-19, many governments shifted focus away from sustained preparedness investments. Unfortunately, pathogens do not pause because political attention moves elsewhere.

I would not say global health agencies are ignoring the risk, but I do believe the world has become more reactive than proactive. The danger is not necessarily that Ebola becomes a global pandemic on the scale of COVID-19, but that repeated outbreaks expose systemic weaknesses in surveillance, rapid response coordination, vaccine access, and health care resilience. Those weaknesses can allow outbreaks to expand further before the world mobilizes an adequate response.

ICT: You’ve pointed to fragile health care systems, population displacement, and cross-border migration as major factors complicating outbreak response. How do these realities change the traditional containment model for Ebola, and what operational challenges do they create for surveillance, isolation, contact tracing, and vaccine deployment on the ground?

DD: Traditional Ebola containment models relied heavily on identifying cases quickly, isolating patients, tracing contacts, and limiting movement within relatively defined geographic areas. Today’s realities make every part of that model more difficult.

Population displacement and migration complicate contact tracing because individuals may cross borders or move between communities before symptoms are recognized. In areas affected by instability or conflict, public health teams may not even have reliable access to affected populations.

Health care infrastructure limitations also create major operational challenges. Diagnostic capacity may be limited, health care workers may lack adequate protective equipment, and rural clinics may not have sufficient infection prevention controls. When frontline health care facilities become transmission amplifiers rather than containment points, outbreaks can accelerate rapidly.

Another challenge is public trust. Effective outbreak control depends heavily on community cooperation. Misinformation, fear, political instability, or distrust of authorities can reduce adherence to isolation measures or vaccination campaigns.

From a vaccine deployment standpoint, logistics remain extremely difficult in unstable regions. Maintaining cold-chain integrity, transporting personnel safely, coordinating with local governments, and reaching remote populations all require significant operational infrastructure. Even highly effective vaccines have limited impact if they cannot be delivered rapidly and consistently to the right populations.

ICT: During COVID-19, many countries invested heavily in pandemic preparedness infrastructure, yet there are growing concerns that global vigilance has declined sharply in recent years. What lessons from both Ebola and COVID-19 do you believe governments still have not fully absorbed, particularly regarding rapid response capacity, international coordination, and sustained investment in infectious disease preparedness?

DD: One of the most important lessons from both Ebola and COVID-19 is that preparedness cannot be built during a crisis. Preparedness requires sustained investment before emergencies occur.

Unfortunately, governments often move through predictable cycles: crisis, emergency funding, temporary infrastructure expansion, then gradual disengagement once headlines fade. That cycle leaves countries vulnerable when the next outbreak emerges.

A second lesson is the importance of rapid-response manufacturing and supply chain resilience. COVID-19 exposed how dependent many nations remain on limited suppliers, overseas manufacturing, and fragile global logistics networks. The same concerns apply to vaccines, diagnostics, therapeutics, and protective equipment for high-consequence infectious diseases.

International coordination also remains inconsistent. Infectious diseases do not respect borders, yet response mechanisms are still often fragmented across agencies, governments, and funding organizations. Faster data sharing, coordinated regulatory pathways, and pre-established response frameworks are essential.

Finally, I do not believe the world has fully absorbed the importance of maintaining public trust. Scientific capability alone is insufficient if communication failures undermine confidence in public health measures. Effective preparedness requires not only technology and infrastructure, but also credible, transparent communication.

ICT: Rapid vaccine deployment is often described as one of the most powerful tools for stopping Ebola outbreaks. Can you explain how Ebola vaccination strategies work during an active outbreak, what barriers still exist to deploying vaccines quickly in unstable regions, and how delays in vaccination can alter the trajectory of transmission?

DD: Ebola vaccination strategies typically rely on what is often called “ring vaccination.” Once a confirmed case is identified, health care teams vaccinate the infected individual's close contacts, as well as the contacts of those contacts, creating a protective buffer intended to interrupt transmission chains.

This strategy can be highly effective when cases are identified rapidly, and contact-tracing systems function efficiently. However, timing is critical. Delays in identifying cases or deploying vaccines allow transmission networks to expand before protective immunity can be established.

The barriers to rapid deployment are often operational rather than scientific. Vaccines may exist but delivering them into unstable regions remains difficult. Challenges include transportation limitations, cold-chain requirements, security concerns, shortages of trained personnel, regulatory coordination, and community hesitancy.

In conflict zones or highly mobile populations, these barriers become even more significant. If vaccination campaigns cannot keep pace with transmission, containment becomes increasingly difficult.

The broader lesson is that outbreak response depends on preparedness infrastructure existing before an emergency occurs. Vaccines are extraordinarily important tools, but they must be supported by surveillance systems, logistics networks, trained health care workers, and coordinated public health operations.

ICT: Many infection preventionists and health care leaders in the US view Ebola as a distant regional threat rather than a realistic operational concern. In your view, what should hospitals, public health systems, and infection prevention programs in higher-resource countries be doing now to prepare for the possibility of imported Ebola cases or future high-consequence infectious disease outbreaks?

DD: Health care leaders in higher-resource countries should avoid viewing Ebola solely as a distant regional issue. Even when outbreaks remain geographically concentrated, global travel means imported cases are always possible.

Hospitals and public health systems should focus on readiness rather than panic. That includes maintaining protocols for the rapid identification and isolation of suspected high-consequence infectious disease cases, ensuring that health care workers receive regular training in infection prevention procedures, and maintaining adequate stocks of personal protective equipment.

Equally important is strengthening laboratory and surveillance capabilities. Rapid diagnostics, real-time information sharing, and coordinated communication between hospitals, public health agencies, and federal authorities are critical during the early stages of any imported case.

Preparedness also requires maintaining operational flexibility. The next major infectious disease threat may not look exactly like Ebola, COVID-19, or mpox. Systems must be adaptable enough to respond quickly to emerging pathogens with different transmission characteristics.

Finally, governments should recognize that biodefense and infectious disease preparedness are national security issues as much as public health issues. Sustained investment in vaccine platforms, domestic manufacturing capabilities, surveillance infrastructure, and rapid-response capacity should be viewed as strategic necessities, not temporary emergency expenditures.
