Global Outbreaks Expose Healthcare Distrust Crisis
The first half of 2026 has witnessed three significant disease outbreaks: Ebola, hantavirus, and diphtheria in Australia. Each outbreak has revealed critical weaknesses in disease detection, communication, and response systems. While each outbreak presents unique challenges, a common underlying factor is distrust in healthcare systems or a lack of reliable information, allowing misinformation to flourish with devastating consequences. Addressing this distrust is essential for improving future outbreak responses.
Ebola Outbreak in the Democratic Republic of the Congo
Distrust, rumors, and misinformation have consistently hindered Ebola control efforts, including the current outbreak in the Democratic Republic of the Congo (DRC). Community surveys have revealed misunderstandings about Ebola, including beliefs that the disease is not real, confusion about diagnostic methods, and low trust in healthcare providers. These issues impede case identification, discourage timely healthcare seeking, lead to case concealment, and undermine public health interventions. For instance, in late May, some DRC residents set fire to a tent operated by Médecins Sans Frontières for suspected and confirmed Ebola cases, resulting in 18 individuals leaving the facility. The trigger was an announcement banning large funeral wakes and gatherings, with authorities taking over burial management from families to reduce infection risk from contaminated bodies and belongings.
In 2014, the World Health Organization developed a safe and dignified burial protocol in response to past outbreaks, emphasizing minimal handling of remains and respect for cultural and religious concerns. The protocol required family agreement before any burial. For families to accept these practices, they must trust both the healthcare providers implementing the protocols and the institutions directing the response. This trust was clearly absent in the incidents at the Ebola treatment center and another facility where family members attempted to retrieve the body of a man suspected of dying from Ebola.
Hantavirus Outbreak on Cruise Ships
Misinformation thrives where trust is weak and communication is absent. Delayed transparent public health messaging allows rumors and speculation to fill information vacuums. This was evident in the recent cruise ship hantavirus outbreak. US-based public health experts noted that the US Centers for Disease Control (CDC) was less visible, slower to communicate publicly, and less internationally prominent compared to previous outbreaks. At the outbreak's onset, top CDC officials did not appear on TV shows or grant interviews about risks to the US public. Historically, the agency would lead coordination for such events. Instead, influencers and others filled the void by spreading misinformation on social media about the virus's pandemic potential, unproven treatments, and false links to vaccination.
Diphtheria Outbreak in Australia
The recent diphtheria outbreak in Australia exemplifies how information vacuums undermine outbreak responses. Warlpiri man Eugene Penhall told Guardian Australia that locals were frustrated by the lack of information about diphtheria, including its causes and prevention. They sought practical information relevant to daily life in communities with overcrowded housing and poor living standards. The challenges are complex, involving inequitable healthcare access in remote areas and dealing with a disease unfamiliar to many health workers and communities for decades. Unlike hantavirus, diphtheria is vaccine-preventable. For vaccination campaigns to succeed, health authorities must improve communication about the vaccine and explore local delivery methods to build and maintain trust.
Strategies to Restore Trust
Transparency in complex outbreak responses requires acknowledging what is known, providing clear explanations for decisions, and also acknowledging uncertainties, including policy drawbacks or scientific unknowns. As knowledge about a disease evolves, public health messages may change, and this should be communicated transparently without being seen as a reversal. Lessons from past events like the COVID-19 pandemic highlight that frequent press conferences, social media updates, and direct public engagement build trust. Different messengers and tailored formats are needed for diverse audiences. Upskilling local health staff, collaborating with community organizations, outreach workers, and local leaders can enhance communication, as these groups often face less skepticism than international agencies.
Community-driven action, such as the Social Mobilisation Action Consortium in Sierra Leone, has proven effective. This initiative engaged communities to take ownership of Ebola prevention, leading to behavior changes in safe burials, early treatment, and acceptance of survivors. It mobilized thousands of community mobilizers and trained religious leaders, partnering with over 30 radio stations. Since the 2014 outbreak, Sierra Leone has reported no Ebola cases. However, building trust during a crisis is difficult when emotional and financial stresses are high. Therefore, proactive efforts to build rapport and shared understanding among healthcare workers, stakeholders, community organizations, and the public are crucial before an outbreak occurs. This approach allows for identifying and addressing concerns, leading to better design, uptake, and trust in measures to control future outbreaks.
