Recurring Ebola outbreaks, particularly in the Democratic Republic of the Congo (DRC), serve as a stark reminder that global health security hinges not only on rapid response but crucially on building systemic resilience. The 2014-2016 West Africa Ebola epidemic, which claimed over 11,300 lives and cost billions, exposed profound weaknesses in global health systems and prompted a re-evaluation of pandemic preparedness strategies. A decade later, repeated outbreaks in the DRC, including the recent ones in 2018-2020 and ongoing concerns, highlight a persistent failure to establish truly resilient health systems, underscoring the urgent need for coordinated and sustainable global health reform.

Lessons learned from past outbreaks emphasize several key areas for strengthening resilience. Early detection and rapid response are critical, as demonstrated by the delays in identifying initial cases in Guinea in 2013, which allowed the virus to spread unchecked for months. Robust health systems with optimized patient management are essential, as overwhelmed healthcare facilities in the most affected countries struggled with shortages of trained staff, medical supplies, and financial resources. This had a devastating indirect impact, significantly setting back treatment for other critical diseases like malaria, HIV/AIDS, and tuberculosis [2, 14].

Community engagement remains a cornerstone of effective response and resilience. Challenges with community trust, stemming from historical neglect and the influx of foreign aid, exacerbated resistance to medical interventions in previous outbreaks. Traditional cultural practices also posed challenges, highlighting the need for culturally sensitive approaches [2, 14]. The post-Ebola era has seen efforts to build more resilient health systems, emphasizing the importance of infection prevention and control (IPC) knowledge and skills among health workers, recognizing their pivotal role in both normal operations and crisis situations [7].

Furthermore, building resilience requires ensuring rapid access to medical countermeasures, including broadening the manufacturing base for essential supplies like vaccines and therapeutics. The European Union, for example, is investing in strengthening vaccine manufacturing capacity in Africa through initiatives like Gavi's African Manufacturing Accelerator [1, 9]. The development and application of rapid diagnostic tests, experimental treatments, and vaccines have also been accelerated by past crises, leading to lasting impacts on infectious disease management and preparedness [2, 5].

The current Ebola outbreaks are not isolated humanitarian events but signal broader structural challenges. They underscore the need for sustained investment in public health systems, collaborative surveillance, laboratory capacity, and rapid response mechanisms, with a strong emphasis on community involvement [4]. The magnitude and speed of international responses to Ebola highlight a significant shift, moving beyond treating health emergencies as isolated medical issues to recognizing them as threats to economic stability, investment, and the availability of essential medical supplies. Integrating healthcare systems, enhancing information sharing, and facilitating resource allocation are crucial for effective crisis response. In nations like Mexico, strengthening healthcare resilience is now considered a strategic imperative, transcending its role as a mere public health goal [8].

Ultimately, the recurring threat of Ebola emphasizes that global health security is only as strong as the most fragile states. Building resilient health systems requires a commitment to collaborative surveillance, safe and scalable care, community protection, equitable access to countermeasures, and effective coordination. Prioritizing investments in research, community education, regional access to essential supplies, and transparent reporting is paramount to prevent future outbreaks from escalating into full-blown health emergencies [9].
