Eastern Congo faces a critical moment as it confronts a new Ebola outbreak while still bearing the scars of its deadliest epidemic in recorded history. Those who lived through the 2018-2020 crisis in cities like Beni are now sounding alarm bells about repeating the mistakes that allowed the virus to claim over 2,200 lives across more than 3,400 confirmed cases. Their testimonies reveal a sobering truth: the biological threat of Ebola pales in comparison to the social dysfunction that enabled its rapid transmission through communities gripped by fear, conspiracy theories, and profound distrust of authorities.

Vianney Kambale Kombi, who contracted Ebola during the earlier outbreak, carries vivid memories of a community paralysed by denial and magical thinking. Rather than accepting the disease as a biological reality, many in Beni attributed the illness to witchcraft or spiritual curses, a belief system that created a dangerous feedback loop of concealment and untreated infection. When people reject the existence of a threat, they inevitably fail to take protective measures, seek timely medical care, or comply with isolation protocols—precisely the behaviours needed to contain a highly contagious haemorrhagic fever. Kombi's recovery itself became an obstacle: neighbours and family members viewed survivors with suspicion rather than hope, making reintegration into normal social life agonising and prolonged.

The psychological and political dimensions of disease denial in eastern Congo deserve particular attention for regional observers. Bienfait Wanzire, another survivor, articulated how competing narratives fractured the community's ability to mount an effective collective response. Some viewed Ebola through a spiritual lens, while others interpreted it as a political fabrication timed to coincide with election campaigns—a conspiratorial frame that implicitly blamed authorities of manufacturing disease to consolidate power. This fragmentation of reality into competing truth claims reflected deeper anxieties about governance, foreign interference, and historical trauma in a region with legitimate grievances about medical exploitation and neglect. When people cannot agree on basic facts, coordinated public health action becomes nearly impossible.

Frontline health workers experienced the brunt of this mistrust. Dr Babah Mutuza Lusungu, a physician at Beni's Dieu Est Grand Medical Centre, lost his uncle and two professional colleagues while simultaneously battling community resistance to his testimony about the outbreak's reality. He described a climate of pervasive suspicion that poisoned relationships between patients, health authorities, international partners, and medical staff. This toxic environment transformed hospitals into feared institutions rather than sources of healing, driving people to seek alternative treatments or hide their symptoms entirely. The irony was brutal: those best positioned to save lives found themselves cast as agents of conspiracy, whether foreign or domestic.

Youth disengagement from response efforts represented another critical failure that survivors now emphasise must be corrected. Dr Lusungu warned that authorities cannot wait until case numbers explode to begin community education and mobilisation. Young people, who often command influence and credibility among their peers, were largely excluded from designing communication strategies or building grassroots acceptance of public health measures. This oversight proved costly, as rumours and misinformation spread unchecked through informal networks where official messaging held little sway. For the current Bundibugyo virus outbreak, which has recorded 550 confirmed cases, 101 deaths, and 19 recoveries as of early June, engaging youth leaders from the outset could represent the difference between containment and catastrophe.

The vaccine dimension adds another layer of complexity to Congo's predicament. While the 2018-2020 outbreak benefited from emergency deployment of proven Ebola vaccines, the current Bundibugyo outbreak lacks an approved vaccine, forcing reliance on older containment methods and community cooperation. Esperance Masinda, who worked for a UN children's agency during the previous crisis, contracted Ebola while caring for her infected husband, a medical doctor. She and her spouse both survived thanks to vaccination, yet their recovery paradoxically isolated them further. Community members warned them the vaccine itself would prove fatal, that they would not live five years, that the medication represented a death sentence masquerading as treatment. These narratives reveal how vaccine hesitancy in Congo is not merely the product of ignorance but rooted in historical medical racism and legitimate fears about experimentation on African populations.

Masinda's eventual community reacceptance offers a fragile hopeful note. As years passed and she and her husband remained healthy, the stigma gradually lifted and neighbours ceased viewing them as contaminated. She emphasises our shared humanity transcends disease designation, a message that could underpin more effective health communication strategies. Yet her experience also underscores the time-intensive process of rebuilding trust after it has been shattered. In a new outbreak spreading with each passing day, authorities cannot afford to wait years for suspicions to naturally dissipate.

The lessons coalesce around a central insight: defeating Ebola requires defeating the social conditions that allow it to flourish. Beni's position as a bustling commercial hub near borders with Uganda and Rwanda means the current outbreak poses regional risks extending far beyond Congo's borders. Misinformation spreads as readily across boundaries as the virus itself, potentially complicating responses in neighbouring countries. Malaysian observers monitoring regional disease surveillance systems should recognise that Congo's struggles with community buy-in and vaccine acceptance are not uniquely African problems but universal human challenges magnified by poverty, weak institutions, and justified historical cynicism.

Authorities in eastern Congo face an urgent imperative to fundamentally restructure their approach to disease communication and response. Rather than imposing top-down directives from distant capitals, effective strategies must be genuinely participatory, engaging community leaders, youth advocates, traditional healers, and religious figures as partners rather than obstacles. Information campaigns must address the specific concerns and worldviews of their audiences rather than simply repeating generic public health messages. Most critically, authorities must acknowledge and address the legitimate sources of community mistrust while building accountability mechanisms that reward transparency and punish deception.

The 550 confirmed cases of the Bundibugyo outbreak represent only the visible portion of transmission already occurring. For every detected case, invisible chains of infection likely extend through communities still gripped by denial and suspicion. The survivors who lived through 2018-2020 are offering Congo a roadmap for avoiding that outbreak's worst failures, but only if their hard-won wisdom is translated into concrete institutional change. Without this transformation, Congo risks not merely repeating past mistakes but compounding them with a less effective arsenal of medical tools. The window for learning from history and preventing catastrophe remains open but is rapidly closing.
