In recent years, the world has grappled with an insidious enemy that operates not with weapons and military might, but with whispers and carefully constructed narratives: disinformation. While false information, or what we often call “fake news,” has always existed, the COVID-19 pandemic shone a harsh spotlight on its capacity to wreak havoc on a global scale. We saw it everywhere – from wild conspiracy theories about the virus being a hoax, to claims that readily available “cures” like Ivermectin could miraculously heal the sick. This wasn’t just random misinformation; it was often highly organized, with a clear intent to erode our trust in the very institutions and scientific advancements designed to protect us. The terrifying reality is that this pattern isn’t unique to COVID-19. We’ve witnessed similar tactics during recent hantavirus outbreaks, where again, the virus was dismissed as fake or deliberately engineered. And in a chilling reminder of the human cost, furious community members in the Democratic Republic of Congo, fueled by misinformation and mistrust, attacked and even torched tents housing Ebola patients. This isn’t just about people being misinformed; it’s about a deliberate assault on our shared understanding of truth, with potentially devastating consequences for public health and societal stability. The speed and reach of artificial intelligence and social media platforms have acted as accelerants, allowing these deliberate distortions (disinformation) and inaccurate statements (misinformation) to spread like wildfire, instantly reaching countless individuals across the globe.
This rise of disinformation is deeply intertwined with growing geopolitical tensions, making health a surprising casualty in a world already struggling with division. We’ve seen Russian “bot farms” actively spreading false COVID-19 information, clearly aiming to undermine Western governments and their efforts to combat the pandemic. Conversely, some Western leaders have contributed to the problem by using divisive and inaccurate terms like “China virus” instead of the scientifically neutral “coronavirus,” fanning the flames of prejudice and distrust. Even within what’s often perceived as the wellness industry, there are parts of the “Big Wellness” sector that actively work to discredit science-based medicine. They promote their own products and alternative therapies, often by sowing doubt about established medical practices and creating a narrative that suggests mainstream healthcare is somehow flawed or untrustworthy. This isn’t just about selling products; it’s about shifting public perception away from proven science towards unverified claims, ultimately putting individual and public health at risk. The lines between genuine health advice, marketing, and outright deception have become dangerously blurred, leaving many individuals confused and vulnerable to harmful misinformation.
The implications of this “infodemic” extend far beyond individual health choices; it poses a direct and significant threat to the very foundations of democracy. Céline Jurgensen, France’s Ambassador to the UN in Geneva, aptly describes the rapid spread of false information and disinformation as a dual challenge, impacting both “health security and democratic resilience.” In the wake of the COVID-19 pandemic, she notes a concerning trend: “increased mistrust towards health authorities, questioning of vaccine policies, and weakening trust in science.” This isn’t a localized issue; it’s a global phenomenon that has “become broader” and “ideological,” sometimes even “institutionalised in its orchestration.” Many of these narratives are explicitly “anti-system, anti-science,” designed to create “broad mistrust in public authorities, international organisations including the UN, and researchers.” Helen Clark, former Prime Minister of New Zealand and chair of the vaccine platform Gavi, goes a step further, calling mis- and disinformation “an existential threat to public health,” representing a profound “crisis of trust.” She highlights the erosion of faith in institutions, science, and vaccines, along with increasing societal polarization. Alarmingly, she points out how “disinformation actors exploit and profit from what they do,” and how individuals are increasingly relying on “AI chatbots and search engines for health information,” often without critically evaluating the source or accuracy. Kemi Akinfaderin, Fòs Feminista’s chief global advocacy officer, echoes this sentiment, describing misinformation and disinformation as “anti-system, anti-multilateralism, and anti-democratic.” She emphasizes that the incredible advances we’ve made in areas like sexual reproductive health and rights, maternal health, and child health, which are primarily “driven by evidence,” are now under a “concentrated effort to erode that evidence.” She points to “concentrated strategic efforts by anti-rights and anti-gender actors, particularly, to undermine scientific evidence and to create distrust in the system,” demonstrating how these insidious tactics are used to roll back progress and further specific ideological agendas.
The impact of disinformation on health outcomes is profound and immediate. Robert Mardini, Director General of Geneva University Hospitals, starkly states that “misinformation and disinformation are no longer sitting at the periphery of our challenges, but very much at the core, front and centre of the daily humanitarian response, but also clinical realities.” These false narratives directly influence how patients interpret their symptoms, whether they seek necessary medical care, how diligently they adhere to prescribed treatments, and how entire communities respond to crucial public health recommendations. The examples are disturbingly common and demonstrate the breadth of this problem. Last year, when Pakistan introduced the HPV vaccine to protect against cervical cancer, Gavi research found that an astonishing 27% of top-ranked Facebook videos in Urdu related to the vaccine contained misinformation, compared to only 17% that supported it. During COVID-19, a fake letter, falsely attributed to a senior physician at the Geneva University Hospital, circulated widely, ludicrously claiming that the vaccine caused infertility – a baseless assertion that nonetheless sowed widespread fear. In another instance, national public health guidance was deliberately distorted and went global, falsely suggesting that Switzerland had declared vaccines dangerous. Kemi Akinfaderin has personally confronted harmful claims in Nigeria and Uganda that contraceptives cause infertility and cervical cancer, with some of these damaging narratives even being spread by women’s rights organizations themselves. Brazil’s Secretary of Health, Dr Mariângela Simão, highlighted her country’s ongoing struggle with vaccine hesitancy, a direct legacy of former President Jair Bolsonaro, who was a “denialist right of both the pandemic and of vaccines.” Prof Alexandra Calmy, who heads the HIV unit at the University of Geneva Hospital, recounted a chilling incident where, the day after US President Donald Trump suggested a link between paracetamol and autism in pregnant women, patients at her clinic refused essential pain relief, demonstrating the immediate and dangerous consequences of high-profile misinformation.
At its heart, this isn’t just a communication problem; it’s a profound crisis of trust. Robert Mardini wisely observes, “Misinformation is not primarily a communication challenge. It is a trust problem.” Dr Sopon Iamsirithaworn, Deputy Secretary of Thailand’s Ministry of Public Health, further emphasizes this, stating, “Trust must be treated as a strategic public asset.” He explains that people don’t simply follow health measures because they receive information; “What really matters is whether they trust the system and believe in the message they hear.” In Thailand, he notes, “trust doesn’t come from the centre alone. It is built at the community level with trusted people on the ground, including our village health volunteers who live in the community,” highlighting the crucial role of local, credible voices. The daunting truth is that traditional health authorities and governments are often no match for the sheer speed and massive scale at which chatbots and generative AI can churn out fake information. However, there are still tools and strategies available to dismantle at least some of this onslaught of fake news, demanding a multi-pronged approach that goes beyond simply correcting falsehoods.
Addressing this monumental challenge requires concerted action on several fronts, fundamentally rethinking how we interact with information and hold powerful platforms accountable. Helen Clark advocates for increased access to “quality health information,” a “much better understanding of the real impact of mis- and disinformation on health incomes,” and, critically, holding tech platforms accountable for their role in disseminating misinformation. She raises crucial questions: “What might regulators insist that they do to clean up their act and stop being the purveyors of the kind of mis and disinformation that is going to cost people’s lives and health?” France’s national strategy for combating health-related disinformation offers a potential blueprint for other nations, according to Céline Jurgensen. The European Union’s Digital Services Act represents another significant step, aiming to “strengthen the responsibility of digital platforms” in clamping down on the spread of illicit or misleading content. Beyond regulation, there’s a strong call to “strengthen regional and international ways that we share information, and to cooperate in early warnings.” Dr Mariângela Simão highlights Brazil’s unique approach within its National Health System, which legally mandates civil society participation, fostering a grassroots engagement that builds trust from the bottom up. Dr Sopon Iamsirithaworn stresses the urgency of “speedy responses to misinformation” and bolstering governments’ “social listening capacity” to truly understand what their citizens are hearing and thinking. Kemi Akinfaderin calls for empowering communities, particularly in the global South, to challenge the dangerous notion that being anti-science is somehow a form of decolonization. Ultimately, WHO Chief Scientist Sylvie Briand eloquently summarizes the path forward, emphasizing the need to “listen, connect, and communicate.” Her division is launching a movement called ‘Together for Science and Health,’ recognizing that collective action is essential. Robert Mardini concedes that misinformation spreads “faster than our collective ability to counter it,” but he offers a powerful vision: “We will not solve disinformation by correcting falsehood faster. We must build systemic resilience by strengthening scientific literacy, investing in transparency, reinforcing links between science and communities, and working through trusted international networks.” He also underscores the critical role of “supporting healthcare workers as trusted communicators,” recognizing them as “the most credible interface between science and society,” provided they receive the necessary time, training, and institutional backing. The fundamental question, he concludes, is not just how we fight misinformation, but “whether we create environments where it cannot easily take root and spread,” building a world where truth and trust can flourish.
